Planning around public holidays
What is an observed or substitute holiday?
When a holiday falls on a weekend, local rules may move the day off to a weekday. The list identifies observed or substitute dates. Check your employer’s or school’s schedule before making plans.
Can I put these holidays on a printable calendar?
Open the 2021 calendar for this country and region. Add personal dates, choose week, month or year, then customize your paper size, orientation and layout in Print settings.
Where do the holiday dates come from?
We use Vacanza holidays (MIT) to calculate dates from country and regional rules. Where available, we check dates against published government schedules, including GOV.UK bank holidays and the US federal holiday schedule. A calculated date follows a rule; it is not a guarantee of an official day off. Dates marked “To be confirmed” may change. Employers, schools and local authorities can follow different schedules.
Dates calculated using the published holiday rules; one-off or local changes may not yet be included.
