Google Calendar - Public Holiday Calendars

calendarID from cal.csv can be used at path param in https://developers.google.com/calendar/v3/reference/calendars/get https://developers.google.com/calendar/v3/reference/events/list

cal.csv

Yes, it does. Just replace the language at the start of the calendar id based on ISO 639 (https://en.wikipedia.org/wiki/List_of_ISO_639_language_codes). For example, this is the link to Slovak holidays in Slovak:

https://calendar.google.com/calendar/ical/sk.slovak.official%23holiday%40group.v.calendar.google.com/public/basic.ics

i updated this json with format with ISO identify name and calender id ,

Does Google Calendar support other languages in this API list?

sure why not just need fetch like proper api url with your Google calender api key (google api console)
https://www.googleapis.com/calendar/v3/calendars/${calendarId}/events?key=${API_KEY}&timeMin=${start}T00:00:00Z&timeMax=${end}T23:59:59Z&singleEvents=true&orderBy=startTime

I wonder how to get other observances, seems to enabling/disabling them in Google settings doesn't affect ics link

@sermelipharo to get other observances just remove ".official" from the calendar name. For example en.usa.official#holiday@group.v.calendar.google.com becomes en.usa#holiday@group.v.calendar.google.com and now includes all observances and not just official holidays.

This is a very useful collection for developers working with Google Calendar holiday data. It could also be helpful for creating tools related to calendrier de grossesse and date-based planning. Thanks for sharing the calendar IDs and ICS format!
