About this calendar data
Source attribution: Open-Source Python-Holidays Library. The calendar snapshot used to build this page is dated 2026-10-11. Holiday dates, names, categories, and regional rules can change; verify important dates with official local sources.
Bridge-Day marks estimated dates and separates public holidays from other listed observances. Non-public entries remain visible for context and do not count as days off in the optimizer by default.
