How to Add Holidays to Outlook Calendar

Outlook supports adding country-specific holiday calendars from a built-in list. The flow differs between Outlook on desktop and Outlook on the web.

Step-by-step

  1. Outlook on the web: Calendar → Add calendar → Holidays → tick the countries you want.
  2. Classic Outlook (desktop): File → Options → Calendar → Add Holidays. Pick countries from the list and click OK.
  3. New Outlook (Windows): Calendar → + Add calendar → Holidays.
  4. Mobile: not directly supported — sync the holidays from the web/desktop and they appear on mobile automatically.

Religious holiday calendars

Outlook offers Christian, Jewish, Muslim, Orthodox, and Hindu religious calendars in addition to country-based ones. Each adds events as a separate read-only category you can show or hide individually.

Remove holidays you no longer want

In classic Outlook, deletion is annoying — the events sit in your main calendar. Switch to a list view, sort by Category = Holiday, select all, and delete. New Outlook lets you simply untick the holiday sub-calendar.
