Daily Flag hangs a single United Nations member on the plate from 00:00 UTC until the next midnight UTC. The country is not random per visitor. A short hash of the date string YYYY-MM-DD picks an index in the 193-member list, so Lagos and Lisbon see the same cloth. If you open the page at 23:50 UTC and again at 00:10, you should expect a new plate, not a streak trick based on your local calendar.
You get five looks. Type a country name — the field offers the full membership as you type — and log it. A hit closes the day; five misses close it the other way. Feedback names the capital and region when you finish. The share block is plain text: date, country, how many looks, a drill streak counted in UTC days, and the URL. No colored glyph grid, no parody of another game’s copy, no demand that you post anything.
Streaks live in localStorage next to the log for that UTC date. Clear the site data and they are gone. There is no login to protect them, and Flag Drill will not email you a reminder. Territories stay out of the daily pool so the worldwide plate is always a UN member. If you want dependencies, use the other quizzes and flip the territories toggle there.
Treat it as a metronome, not as a personality score. Geography trivia is practice. Come back tomorrow because the hash will have moved, not because a calendar app guilted you. When you want volume after the daily plate, the twelve-question flag quiz and the full-world pass are in the header. Flags still come from flagcdn.com; the membership file is local to this Worker.
