Which cron syntax does this support?

Standard 5-field cron: minute, hour, day-of-month, month, day-of-week. Supports * (any), N (literal), N-M (range), N/X (step), and lists like 1,5,15. Day-of-week 0 and 7 both mean Sunday.

What about Quartz, AWS Events, or Vixie cron extensions?

Some platforms add a seconds field (Quartz, AWS) or non-standard "L", "W", "?" tokens. This tool sticks to portable POSIX cron — if you're using a 6-field format, drop the seconds field for parsing here.

Why are next-run times shown in my local timezone?

Cron schedules are usually evaluated in the server's timezone. We show your browser's local time so you can sanity-check the cadence. Make sure your production environment is configured for the timezone you expect.
