What a cron translator does
A translator starts from an expression you already have — `0 9 * * 1` — and says what it means. CronGPT does the opposite: English in, expression out.
How to read the five fields
Minute, hour, day of month, month, day of week. `0 9 * * 1` is minute 0, hour 9, every day of month, every month, weekday 1 (Monday).
Common gotchas
If both day-of-month and day-of-week are set, Unix ORs them. 0 and 7 are Sunday. Crontab uses the machine clock; CronFox production uses the service clock.
When to use the other tools
Validator checks syntax. Calculator lists many upcoming times in another timezone. CronGPT writes a new expression from English.
Same format on CronFox
HTTP tasks store this Unix 5-field string on cron_expression_1. Deploy saves a 24-hour browser draft, then opens New Task after you choose a collection.
