About this tool

Text to Cron Generator reads a schedule written the way a person would say it and produces the matching 5-field crontab expression (minute, hour, day of month, month, day of week). It is the reverse of a cron explainer: instead of taking a cron string and describing it, this tool takes a sentence like "every weekday at 9am" or "on the 1st of every month at midnight" and writes the cron for you. The parser is deliberately deterministic rather than a fuzzy language model. It recognizes a defined vocabulary of scheduling phrases and reports exactly which parts it understood, so the output is never a silent guess. The recognized phrases cover what people actually write: frequency (every minute, every 5 or 10 or 15 or 30 minutes, every hour, hourly, every 2 or 6 or 12 hours, daily, weekly, monthly, yearly), time of day (at 9am, at 9:30am, at 17:00, at noon, at midnight, and lists such as at 9am and 5pm), days of the week (every day, every weekday, every weekend, on Monday, on Mondays and Fridays, Mon-Fri, Monday to Thursday), days of the month (on the 1st, on the 15th, on day 1 and 15, and the last day of the month), and months (in January, in Jan and Jul). When a day, weekday, or month is specified without a time, it defaults to midnight so the job fires once on the matching day rather than every minute, which matches how most people read a schedule. Times of day take precedence over an interval reset, so "every hour at :30" keeps minute 30. Phrases that cannot map to a standard crontab, such as sub-minute timing or the last-day operator, are flagged with a clear note rather than producing a misleading expression. Every field is shown with a plain-English meaning in the breakdown table, and you can copy the cron with one click. Everything runs locally in your browser, so the text you type is never uploaded or stored.
