FAQ
What format does this support?
Standard 5-field cron: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, where 0 is Sunday). It does not support the optional seconds or year fields.
Does it support ranges and steps?
Yes. You can use * (any), ranges like 1-5, lists like 1,3,5, and steps like */5 or 1-10/2.
What timezone are the execution times in?
All times shown are in your local browser timezone.
Does it support named days/months (MON, JAN)?
Not currently — use numeric values. 0=Sunday, 1=Monday, etc. for weekdays; 1=January, etc. for months.
Is this the same as crontab?
Yes — this parses standard Unix crontab syntax. If your cron implementation adds a seconds field or year field, strip those before pasting.
