placing a group in maintenance schedule

Question

Hi all,

I would like to place a group of servers in Maintenance mode on multiple dates that follow no specific / defined order (such as the 1st Monday of every week).

how can I go about implementing the same? do I have to create multiple schedules or is there some kind of workaround?

for reference the dates I would like to place the group in maintenance are:

1. Good Friday: Sadly, every year a different date (but always the last Friday before Easer)
   i. 2023: 7 April
   ii. 2024: 29 March
   iii. 2025: 18 April
   iv. 2026: 3 April
   v. 2027: 26 March
   vi. 2028: 14 April
   vii. 2029: 30 March
   viii. 2030: 19 April
2. Easter: Sadly, every year different dates (but always on a Sunday and Monday). Below focusing only on the Mondays as these servers are already (to be) scheduled for Maintenance Mode every weekend (sat sun).
   i. 2023: 10 April
   ii. 2024: 1 April
   iii. 2025: 21 April
   iv. 2026: 6 April
   v. 2027: 29 March
   vi. 2028: 17 April
   vii. 2029: 2 April
   viii. 2030: 22 April
3. Ascension Day: Sadly, every year different dates (but always on a Thursday).
   i. 2023: 18 May
   ii. 2024: 9 May
   iii. 2025: 29 May
   iv. 2026: 14 May
   v. 2027: 6 May
   vi. 2028: 25 May
   vii. 2029: 10 May
   viii. 2030: 30 May
4. Whit Monday: Sadly, every year different dates (but always on a Monday).
   i. 2023: 29 May
   ii. 2024: 20 May
   iii. 2025: 9 June
   iv. 2026: 25 May
   v. 2027: 17 May
   vi. 2028: 5 June
   vii. 2029: 21 May
   viii. 2030: 10 June

Your assistance is greatly appreciated :).
