Please vote for this issue if you agree that Team Calendars should have an option to repeat events on weekdays: https://jira.atlassian.com/browse/CONFSERVER-65483
Microsoft Outlook has an option to repeat calendar events on weekdays. For example, repeat an event on the first/second/last weekday of each month.

Confluence Team Calendars only has the option to repeat events on specific days (M, T, W, Th, F, S, Su) or "Day" (example: first day of each month), but no option to repeat on the first working day/weekday of each month.

Allowing the dropdown option to repeat events by weekday in Team Calendars is essential, in my opinion. I hope that if we get enough votes, this feature can be implemented in Team Calendars soon. Thank you for your help!
