Notes
A cron expression has five fields — minute, hour, day-of-month, month, day-of-week — each accepting a number, * (every), */n (every n), a list (1,15) or a range (1-5). Day-of-week runs Sunday=0 to Saturday=6.
Note on timezone: plain cron runs in the server's local time. GitHub Actions cron always runs in UTC — convert your intended local time before setting it.
Other schedules: every minute · every 5 minutes · every 10 minutes · every 15 minutes · every 30 minutes · every hour · every 2 hours · every 6 hours · every 12 hours · every day at midnight
