How human readable cron translation works

CronWave reads each field of the expression, works out which values match, and builds a sentence from them. 0 9 * * 1-5 becomes "Every weekday at 9:00 AM" rather than a list of field values. Because the same engine also powers the other tools, the sentence always agrees with the next-run times shown elsewhere.

Some expressions do not summarise neatly. When day-of-month and day-of-week are both restricted, or a step does not divide evenly, the text spells out the exact values instead of rounding them into something that sounds nice but is wrong.

Frequently asked questions

It is a plain-language translation of a cron expression, such as turning 0 9 * * 1-5 into "every weekday at 9:00 AM".
It is good for reviews, documentation and tickets. Before you deploy, also check the platform syntax and the time zone with the validator.
Cron describes which calendar values match, not intent. Expressions that restrict both day-of-month and day-of-week, or that use unusual steps, cannot always be summed up in one natural sentence, so the tool spells them out.
