Sources and last check
Times, offsets and sun positions on this page are computed live from the IANA timezone database and the NOAA solar algorithm, so they do not depend on the review dates below.
- Public holidays for 120 countries, 2025-2028
- Source: date-holidays, generated by scripts/build-holidays.mjs. Last checked, reviewed every 12 months.
Not covered:Public holidays only, including statutory substitute days; regional and observance days are excluded. 21 of our countries are not in the dataset and have no calendar. Regenerate on every date-holidays upgrade: the 25 July build silently lacked Korea's substitute days because the installed package predated them. Known upstream gap: El Salvador — the source lists 8 public days where Nager.Date confirms ~20, and files New Year's Day as an observance; we publish what the source holds rather than invent, and the weekly Nager run tracks the gap. - Working hours and weekend days for 55 countries

Not covered:A national convention, not any given employer. Countries not listed fall back to a nine-to-five, Monday to Friday default, and pages say so rather than implying we checked.
