Daily flag challenge

The daily flag changes at midnight in your own time zone, and everyone gets the same flag on the same calendar date. Easy and Hard follow separate schedules, so the two flags on a given day are unrelated.

There are 57 flags in the Easy set and 140 in the Hard set. Each set is shuffled once per year and then played in order, so within a year every flag in a set comes up before any flag repeats. Easy therefore cycles roughly every 8 weeks, and Hard about every 5 months.

Only the flag is on a daily schedule. The outline challenge picks a new country each time you start it, and Geo Sort has its own daily set of eight countries.
