Flag Calendar
Know when to fly the flag
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New in 1.1: the United States, Australia, New Zealand and Canada. Every flag day with its hoisting time, mast height and a link to the regulation behind it.
People fly the flag on different days, and in different ways. Norway hoists at eight in summer and nine in winter, later still north of the Arctic Circle. Lithuania lowers the flag a third of the way, not half.
Flag Calendar carries the rule as each country wrote it: the days, the hoisting and lowering times for your date and place, and whether the flag flies at full mast, half or one third.
The app carries more than 50 countries and territories and more than 600 flag days. Almost every one is taken from the government's own regulation and linked back to it. Where a state publishes no flag-day instrument at all, the app says so plainly instead of leaving a gap.
FREE
- Your country's flag days for the year ahead
- Hoisting and lowering times worked out for your date and place
- Full mast, half mast and one third, exactly as the rule says
FULL ATLAS (one-time unlock)
- The background to every day and the rule that governs it
- Reminders the evening before and on the morning itself
- A link to the regulation behind each day
- Home screen widgets and an Apple Watch app
Movable days are computed, not guessed. Easter, midsummer, Advent and the weekday rules are worked out from the same definitions the authorities use, so the dates hold for any year.
Everything runs on your device. No account, no network, no tracking, no ads.
Fly it right.
