FAQ

How many fields is this cron?

The standard five (minute, hour, day, month, weekday), which works with crontab, Vercel Cron and most CI schedulers.

How are weekdays written?

0 and 7 both mean Sunday, 1 to 6 are Monday through Saturday, and abbreviations like MON and TUE also work.

Does it support */5?

Yes. Steps, ranges and lists (for example 1-5 or 1,15) are all parsed and described.
