Our Wedding Planning Timeline and Checklist Will Guide You Through Planning Your Big Day

12+ Months: Draft a Guest List

If deciding who's coming (and who isn't) threatens to either bankrupt you or start a war with your families, many wedding planners recommend scaling back and honing in on the people who really matter. "Look at extending invitations not as a social obligation, but as being surrounded by those you love and who love you," says Todd Fiscus of Todd Events. When couples are on the fence about someone, he suggests imagining you're hiring a car to take friends to dinner at a great restaurant followed by a night out dancing. Ask yourself whom you would most like to spend that kind of evening with instead of including "all the people you work with and everyone at your church."

12+ Months: Set a Budget

Before you begin any sort of planning, it's crucial to determine how much you're willing to spend. While tradition deems the bride's parents responsible for wedding costs, modern day celebrations rarely stick to that rule. Instead, sit both your parents and your groom's parents down and politely decide if they'll be contributing, and if so, how much and for what.

12+ Months: Find and Secure Your Venues

"Draw up your guest list before booking your venue," says David Stark of David Stark Design and Production in Brooklyn. "There's nothing worse than falling in love with a locale and wanting way more guests than it can accommodate." Every wedding venue has its pluses and minuses, so find a spot that's convenient, exciting, and cost-effective.

Throwing an outdoor fête? Make sure you love your rain plan as much as your alfresco vision so you don't spend your engagement stalking meteorologists. Bicoastal planner Lyndsey Hamilton of Lyndsey Hamilton Events suggests booking a tent six months ahead so you won't be scrambling last minute. You can always cancel it if the weather looks good; you may lose your deposit but will have gained peace of mind.

12+ Months: Set a Wedding Date

Once you love a venue, set a wedding date. Avoid holiday weekends, Stark says. "Travel is more expensive for guests, and you'll pay staffers overtime for working a holiday," he says.

12+ Months: Book a Planner, If Using

A wedding planner can help find and negotiate with the other vendors you'll want to start hiring now as well. Make sure that you interview your prospective wedding planner to ensure that you have the same vision in mind. You'll also want to get a feel for their communication style, and how they have planned other weddings at similar budgets to yours.

12+ Months: Put Together Your Wedding Party

Ask people who love and support you to be attendants. You don't need an even number of groomsmen and bridesmaids. Loved ones don't come in matched sets; your wedding party doesn't have to, either.

9+ Months: Begin Registering

People will send gifts starting with the first party thrown for you, be it an engagement celebration or a shower. Set up your wish list (ideally, at two national stores and one local) to make their lives easier.

9+ Months: Order Your Dress

It can take up to nine months for a gown you've ordered to be made; if you select one early, you'll avoid rush fees. Very short engagement? Don't panic. Purchase a sample from a bridal shop, or buy off of the rack from a store or resale website.

9+ Months: Book the Caterer, Photographer, and Band or DJ

If the venue doesn't provide food, you'll want to start looking into catering companies now. When hiring a photographer or videographer, ask to see an entire wedding he or she has shot, not just the highlights. Also, secure the band or DJ for your big day.

9+ Months: Help Your Guests

Consider booking a block of hotel rooms for out-of-towners to stay in. And while you're at it, begin to build your wedding website, where guests can find travel information and RSVP.

6 to 9 Months: Order Stationery

The first hint guests will have of your wedding's style is your invitations. Make sure they represent it well. Sending something too cutesy is confusing if you're having an elegant, formal wedding. "If the stationery is discordant, you might accidentally prepare people to dress inappropriately," says Clark. If you're using a calligrapher, now would also be the time to book his or her services.

6 to 9 Months: Send Save the Dates

Once your stationery has been ordered, send out save-the-dates. They're best for destination weddings or any other celebration that requires extra guest planning or travel booking, but most couples send them for any type of wedding—it just adds to the excitement building of the big day!

6 to 9 Months: Book the Florist

Do you want a florist who just deals in blooms or an event designer who handles flowers, lighting, and décor? Naturally, you'll want a bouquet and centerpieces (which should either be shorter than 14 inches or raised more than 24 to allow for conversation). But will you use flowers in other ways, such as for a cake topper or favors or to decorate a chuppah? Either way, choose blooms that are in season. If specific flowers are a big part of your dreams, plan your wedding around when they're available. "You're not going to get peonies in September," says Jeannie Savage of Details, Details in Los Angeles, California, unless you're willing to pay to have the late-spring buds imported.

It's helpful to bring your florist images of arrangements you love and lists of your favorite flowers and those that hold sentimental value to you (maybe you want to echo the ones your grandmother carried in her bouquet). If there are blooms you want that are hard to find or expensive, use them sparingly in arrangements or save them for your bouquet.

6 to 9 Months: Hire the Officiant

If you're getting married in your church, synagogue, mosque, or temple, you likely know the clergyperson who'll be performing your service. When a ceremony combines religions and cultures, a Unitarian minister is a good option. A judge or justice of the peace will serve if making it legal is what counts. And if you would like to be wed by a friend or relative, he or she can become ordained online (try themonastery.org). Whatever route you choose, call the city or county clerk's office where you'll be marrying to see if you need to complete any extra procedures.

6 to 9 Months: Order Bridesmaid Dresses

Your day-of dress isn't the only thing to think about. Now's the time to choose what your bridesmaids will be wearing, from color (solids or prints?) to style (uniform or mismatched?) to length (long, short, or something in between?). Make sure each 'maid has her dress ordered within this time frame as well.

6 to 9 Months: Plan Your Honeymoon

It may feel far away, but travel plans always require time. Figure out where you want to go, and get started booking based on where you're headed and when.

4 to 6 Months: Factor in Food and Music

Not all receptions need to involve a five-course dinner and dancing. Yours could be brunch, a cocktail affair, or an intimate family-style gathering. The few musts: The food, the cake, and the music ought to reflect you as a couple, work with the other elements of your celebration (a string quartet doesn't jibe with a barbecue picnic), and delight guests. So order your cake, determine your menu (and hold a tasting two weeks out), and discuss your music options between these months.

Also, consider how guests will be served: A series of stations is ideal for a cocktail reception, while plated service is appropriate for a black-tie one. (And it's always fun to use a family recipe and share the story behind it.) Then, be sure to feed your vendors and ask for some food to be boxed up for later when you're starving. This is also a good time to hire a lighting designer, if using. If not, ask your venue about options for illuminating the band, DJ, or dance floor.

4 to 6 Months: Devise a Reception Timeline

Copy ours below, or create your own play-by-play to keep things moving smoothly.

0:00 Cocktail hour starts.

1:00 The couple enter and have their first dance.

1:30 At a sit-down dinner, the first course is served. The host and best man offer toasts.

2:30 The main course is served.

3:00 The newlyweds dance with their folks; guests join in.

3:50 The cake is cut.

4:00 Cake and dessert are served.

4:45 The bouquet is tossed.

5:00 The bride and the groom depart.

4 to 6 Months: Book Rentals

We're talking tents, tables, linens, you name it. When it comes to tables, you can mix square and round shapes at your reception. The only caveat: If you're going for rectangular tables, separate them every 50 people (25 per side), suggests Stark. Any longer and guests may have to walk around to get to the dance floor or restroom. Staffers will have to do the same to serve, delaying dinner.

If you're having a seated dinner, guests feel awkward when they don't know where to sit. Designate their table or a specific spot with a place card. Organize escort cards by alphabetizing last names (instead of listing guests by table number) so people can find theirs quickly, says Kathryn Kalabokes, of Dream A Little Dream in San Francisco, California. Otherwise, it takes them much longer to figure out where to go, she says. Also make time to book any needed transportation, including limos or party buses for the day-of.

4 to 6 Months: Begin Dress Fittings

Now that the dress is ordered, you'll need a few extra appointments to ensure that it fits like a glove. Start now so you have plenty of time for alterations.

4 to 6 Months: Plan Your Rehearsal

Book any spaces and make dinner reservations for day-before prep. Be sure to also figure out your rehearsal dinner guest list, and send those invitations out now, as well.

2 to 6 Months: Mail Invitations

All invites should be sent at least six weeks ahead, allowing your guests adequate time to respond and ensuring that you'll get a reliable head count a week or two before the event. For destination or holiday weekend weddings, the earlier they're sent, the better.

2 to 6 Months: Plan the Service

When it comes to walking down (and back up) the aisle, you can stick to the standard order. The groom waits at the altar as the wedding party enters, then the ring bearer and flower girl. Next, the bride is escorted by her father or parents. Or, mix it up. You might ask a person of mutual importance to escort both of you, one on each arm; walk one behind the other with your respective parents; or proceed down the aisle together hand in hand.

Traditionally, the bride's guests sit to the left of the aisle and the groom's to the right (or the reverse for a Jewish wedding). Reserve the first rows for family, then have ushers escort guests to a spot on the groom's or bride's side of the aisle, or let attendees know it's open seating with a sign that says, "Have a seat—anywhere!"

2 to 6 Months: Personalize the Ceremony

Customize your service by choosing songs and readings, or by writing your vows. Look to poetry, literature, song lyrics, and even your own love letters for inspiration. Feel free to think outside the Canon-in-D processional, and pick songs that really speak to you, Kalabokes says. For her own wedding, she chose "I've Got You Babe" for everyone to walk in to, and Queen's "You're My Best Friend" for the recessional.

2 to 6 Months: Book the Hairstylist and Makeup Artist

Schedule hair appointments for three hours before and makeup appointments at least an hour before; you won't be harried, and attendees won't be kept waiting. Also, test-run a few different options beforehand. No bride wants an unsightly surprise the day of!

2 to 6 Months: Place Some Orders

By this time, flowers should be decided on, favors should be bought, and outfits for the groomsmen should be ordered.

2 Months: Get Buying (And Asking)

Order gifts for your wedding party, as well as any extras for the wedding day. These include everything from cake knives and toasting glasses to guest books and unity candles.

And while you're treating them, let them treat you, by asking your closest guests if they'd be willing to deliver a toast.

6 Weeks: More Essentials

Are you doing a garter toss? Buy the garter. Have your rings been bought? Get them now. Want a signature cocktail at the reception? Start concocting.

And make sure your venue has its loose ends tied. Power, for example, is a huge thing to check on. Is there enough for your performers and décor? Where are the outlets?

4 Weeks: Chart, Schedule, and Plan

By now, your ceremony should be finalized, but small details still need to be taken care of. Arrange seating charts, confirm who'll be reading and toasting, write your vows, and print your programs. Also, send your vendors a day-of schedule so they're on the same page.

4 Weeks: Secure Your Marriage License

Be sure to check with your local municipality—different states have different rules for how far in advance you must secure your marriage license, and you won't be official without it!

2 Weeks: Confirm Details

Make sure your photographer knows the shot list and your band or DJ knows the playlist. Whoever's decorating the reception site should be well informed, and transportation leaders should be assigned if lots of site-to-site guest travel is involved.

Also, run the final head count by your caterer. There's nothing worse than having too little food!

2 Weeks: Break in Your Shoes

Wear your wedding heels around the house—your feet will thank you later.

Week-Of: Use Those Vacation Days

Job permitting, "take a few days off before the wedding," says Karen Kaforey of Signature Events Nashville. "You need the time to wrap up details, greet traveling friends and family, go to appointments, and breathe!"

Details to Wrap Up

• Picking up your dress and the rings
• Putting together favors and welcome bags
• Confirming delivery and arrival times with the vendors, hairstylist, and makeup artist

Tasks to Assign

• A guest-gatherer for photos on wedding day
• A day-of point person for guest questions and concerns
• Someone to take wedding gifts home post-reception

Week-Of: Start Packing

Think like a Boy Scout, and be prepared. You'll need all of the following gear on the big day.

You Should Bring

• Your dress, shoes, undergarments, and jewelry
• The groom's and attendants' gifts (if you didn't give these tokens of appreciation the night before)
• Your vows, if self-penned, and the wedding bands to hand off to the best man

Your MOH Should Bring

• Ibuprofen
• Bobby pins
• A sewing kit
• Earring backs
• Buttons
• Krazy glue
• Deodorant
• Baby powder
• Stain remover

Day Before: Final Arrangements

Day-before tasks include everything from arranging tip envelopes (for certain vendors and waitstaff) to preparing snacks for the getting-ready rooms (unless they've been pre-ordered through your caterer).

To look your best on your special day, invest in a mani and pedi (you'll need the break, we promise!), and after confirming times and addresses with your transportation (limo, etc.) service, head over to your rehearsal dinner to practice, practice, practice.

Day-Of: Take Care of Yourself

Naturally, you'll have butterflies in your stomach. But these tactics will keep you smiling and glowing.

Hydrate: "It's not just an important day, it's one of the most 'talky' days of your life," Savage says. Sip water regularly as your wedding day approaches, and take it easy on the alcohol. And while a massage sounds relaxing, don't have one just before the wedding; it can be dehydrating.

Eat: Breakfast has never been more vital. Be a blushing—not fainting—bride.

Don't Rush: You can take your time, within reason. Allow up to 15 minutes for stragglers to find seats, but don't annoy guests with excessive primping.

Day-Of: Get Technical

Charge your phone (just in case!) and gather family and guests for pre-ceremony photos. For the best natural light, plan portraits using the Sun Seeker app.

Day-Of: Enjoy It!

Your monumental day will go by so fast. Take care to stay in the moment.

First, stay close to your new spouse. "Try to stick together the entire reception," Kaforey says. "Having shared moments of your wedding is so important to set off on your life as a couple."

Also, don't forget mom and dad. If you have a good relationship with your parents, build a memory by having a moment with them after you're dressed, Savage suggests. "It gets forgotten in the first look with the fiancé." The same reasoning goes for your siblings or a grandparent.
