Wedding planning timeline and checklist
Wedding planning usually starts 6–12 months before the wedding. Popular venues and dates fill up fast, so book the venue first, then lock in photography, jewelry and the honeymoon, and finish with invitations and details last.
| Time remaining | Key tasks |
|---|---|
| 6+ months | Book venue, set budget, family meeting, start home search |
| 3–6 months | Book photography & attire, jewelry, honeymoon, invitation design |
| 1–3 months | Wedding shoot, send invitations, guest list, buy furnishings |
| 2–4 weeks | Rehearsal, finalize program & speeches, prepare favors, move-in prep |
| Within 1 week | Final checks, beauty & skincare, confirm rings & attire, day-of logistics |
This timeline is a typical flow; the order and timing can shift with your wedding size (intimate, small wedding, hotel) and personal situation. To plan your budget alongside it, use the wedding budget calculator; for home funds, use the newlywed funds calculator.
Frequently Asked Questions (FAQ)
How is the D-day counted?
The wedding D-day is the difference in days between today and your wedding date. If the wedding is 30 days away it shows D-30, the wedding day itself is D-day, and after the wedding it shows D+number. This calculator counts dates only, ignoring time of day.
How many months ahead does wedding planning usually start?
To secure a venue and popular dates, planning usually starts 6–12 months before the wedding. Venues are often booked 6+ months ahead; photography, jewelry and the honeymoon 3–6 months ahead; invitations and details 1–2 months ahead; and rehearsals and final checks 1–2 weeks ahead.
Do I have to do the checklist exactly at those times?
No. The checklist is a reference guide organizing the typical wedding planning flow by stage. The order and timing can change with your wedding size and personal situation, so adjust it to your own schedule.
