A timeline is important because it keeps the day moving smoothly as well as helps everyone be on the same page. Timelines can vary based on many factors such as, if you're doing a 1st look or not, your ceremony time and length, order of reception events and much more. Below I will show you an example timeline with how much time should be allowed for each part of the day. This will include buffer time in case the timeline falls behind at any time of the day.
