Accuracy matters
We welcome clear corrections supported by an official source. Reports are reviewed against the applicable authority, jurisdiction and year before a calendar is changed.
How corrections are handled
We verify the claim, update the affected page when warranted, and review related calendars that may use the same date. Material corrections should identify the country or region, holiday, year and supporting source.
