The wedding day timeline tool is to help you visualize how your wedding day will run.
A wedding day timeline, also known as a run sheet, is a document commonly used in the events industry to help everyone involved in the event understand how the day will run.
Around the 3 week mark from your wedding day, your venue coordinator and other vendors will most likely ask you for this document so they know when to be at the venue and can plan their schedules accordingly.
To create your timeline, the first thing Wedsites will ask you is when your ceremony will begin. If you don't know this yet, you can skip this and come back to it later.
If you're unsure about how to structure your wedding day, this resource has some great examples of what a typical wedding day looks like!
