Standard 5-field cron only (minute hour day-of-month month day-of-week). Runs entirely in your browser.

Field reference

A cron expression has five space-separated fields, in this order: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, where 0 is Sunday). Each field accepts * (every value), a single number, a range like 1-5, a comma-separated list like 1,15,30, or a step like */15.
