Does your timetable have any sort of repeating structure, or is it entirely ad-hoc? Gibbon let’s you define the structure of a day, using Timetable Columns, then add those days to your timetable using Timetable Days. These timetable days are then associated with a specific date. So, even though many schools use the timetable days for days of the week, you could use these Timetable Days for any of your days that have the same structure.
Otherwise, if your timetable changes too frequently, then the timetable in Gibbon is likely to be too rigid for your needs. Another option is is you use Google single-sign-on, which enables integrating school and personal calendars into the timetable, which would allow you to change the Google calendar events as often as you need.
Hi Islam, it may help to share a visual of your timetable, if you’re able to, since there are many ways to approach constructing a timetable in Gibbon, this may help us give you some suggestions. Thanks!
