Is there an alarm clock with a production calendar?

Question

Google Calendar

I would like to finally solve the issue of the alarm clock for the classic five-day period.
Task: 1 Integrate an alarm
clock with a production calendar (holidays, days off, shifts of working days) - automated input / annual manual
update this feature. Example: built-in Xaiomi alarm clock before MIUI 8 (but it is tied to the Chinese calendar).
2 Forward integration through google calendar. Example: uploading a ical factory calendar, setting up notifications on it in Calendar Event Reminder or Alarm Calendar Plus (Suddenly, the problem turned out to be in finding a shared google Factory calendar / imported ical factory calendar).
Who solved this problem and how? I'll be happy to hear your ideas!
