How to use this calculator
Enter minute, hour, day-of-month, month and weekday fields. Choose a starting instant, search range and repeated-time policy.
Supports lists, ranges, steps and English month or weekday abbreviations. Restricted day-of-month and weekday fields combine with OR; when either starts with a wildcard they combine with AND. Search is strictly after the entered instant and covers at most 366 calendar dates.
A worked example

Will this run my scheduled task?
No. This is a schedule preview. Scheduler dialects and daylight-saving policies vary; compare the supported syntax and repeat policy with your scheduler.
Which calendar and years are supported?
Each result states its calendar, time scale, precision and supported range. Batch converters accept up to 100 nonempty input lines and retain invalid rows. Copy, CSV and print include the calculation rules. Calendar downloads appear when a result contains dated events. Calculations run in your browser; no reminders or jobs are scheduled.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
