Almost every couple builds this the wrong way round. They start at the top with "hair at nine" and work down, and by lunchtime the whole thing has drifted forty minutes and nobody knows it yet. The ceremony start is the one time on the entire day that cannot move, so that is the one you put down first and build out from.
Everything here is a starting point, not a verdict. Change a length and everything after it moves. Nudge a single row and everything after that moves with it.
The songs are not in here, the timing is. This page says the first dance happens at 6:40 so the kitchen and the photographer know. Which song plays lives on your Music Run Sheet over in The Whole Damn Day, and that is the page you hand to whoever runs the sound. Two pages, two jobs.
Why this starts an hour before the ceremony and not at breakfast
Because nobody can hand you your morning. It depends on how many people are in hair and makeup, whether you are getting ready at the venue or forty minutes away, and whether you are doing a first look. Vendors are just as spread out. Some walk in ninety minutes before the ceremony and some are there at seven in the morning. Any template that claims to know all that is guessing, and a wrong time on a printed schedule is worse than no time at all.
So build the front of your day yourself with Add a row at the top, and put your vendor arrivals in as you confirm them. Three things that will keep it honest:
Hair and makeup runs long. Always. Take the artist's per-person estimate, multiply by how many people, then add one more full slot on the end. That extra slot is the one you will use.
Double your travel time, then add fifteen minutes. The fifteen is for the part where nobody can find the bouquet, the rings, or one groomsman.
Count backward, not forward. Start from the first row below and work back toward breakfast. If you build down from when you wake up, every delay lands on the ceremony.
Looking for which song plays for the first dance? That is a music cue and it lives on your run sheet. Build it in The Whole Damn Day and hand that page to whoever runs the sound.
