Sources for the 2027 holiday dates

Every date on this site comes from the law or official publication named below. All entries were last updated on 2026-10-12. Links are given only to a few official sites; the other publishers are named in words so you can find them yourself.

The dates and .ics files are generated with automation from these sources; they are not presented as human-curated. This is not an official government product and has no government affiliation. No warranty: dates may change by government decree, so check the official source before relying on them.
