How to Use
Paste any 5-field cron expression and read exactly what it means plus the immediate next run times, computed second by second from right now.
Steps
Enter a cron expression such as */5 9 * * 1-5.
Optionally set how many future runs to list, and a start instant.
Click Parse and read the field breakdown plus the next run times.
Supported syntax
The five standard fields: minute, hour, day-of-month, month, day-of-week.
Stars, step values such as */15, ranges such as 9-17 and lists such as 1,5.
Month and weekday names are accepted, for example jan, dec, mon and sun.
When both day fields are restricted the OR rule applies, as cron specifies.
Features
Next run times are searched minute by minute so nothing is skipped.
Month and weekday names make schedules easy to read and write.
All computation happens locally, nothing is sent anywhere.
