Questions answered

What to know before using the result.

Can I change the suggested wedding milestones?

Yes. The dates are a starting framework; supplier availability, venue rules and your event size should determine the final schedule.

When does the timeline begin?

The first default checkpoint is 12 months before the wedding, followed by 8, 6 and 3 month milestones and final confirmations.

What if my wedding is less than a year away?

Use the sequence as a priority list and move overdue items into the earliest practical planning window.
