Bug with Odd and Even week .ics exports

[onx001]

Describe the bug

The ICS exports do not account for recess weeks when calculating odd and even weeks in Google calendar

To Reproduce

Steps to reproduce the behavior:

1. Add odd/even week slots to timetable
2. Export timetable as .ics file
3. Import it on gcal
4. View slots on ics file after recess weeks
5. See error in allocating odd/even weeks

Expected behavior

Odd/even week calculation is supposed to exclude the recess week and continue as per normal

Screenshots

Here google saves it as weekly

Here it double counts after week 11 due to weeks 12 and 13 not being specified

Worsened problems on GCal android

Great catch, and thanks for creating the issue! I can reproduce this

update saturday: nvm, seems to work fine on gcal for me? I feel like I've experienced this before though, but if it works for you too let's close this for now until we figure it out

Edit: problem has been refined to a specific case for further review and testing. Appears to be a problem with 1. Defining Odd/Even weeks in website/src/utils/ical.ts
Possible solution: CSV export format for android google calendar users due to weird ics input reformatting with gcal on android.
Update: currently working with modifying ICS export format to be more robust
