Build expressions and inspect upcoming runs in your time zone.

Open tool

Put it to work

For 09:00 on weekdays, use 0 9 * * 1-5 with Asia/Seoul selected.

From input to output

  1. Open Cron schedule and load the example.
  2. Read the format notes, choose your options, and replace the example with your input. Start with test data instead of sensitive information.
  3. Run the tool and inspect the result and status. If an error appears, correct the input format and run it again.
  4. Copy the output or download a file. Generated and converted results are not saved automatically.

Scheduling weekday mornings

Set minute to 0, hour to 9, day and month to *, and weekday to 1-5 for Monday through Friday at 09:00. If your scheduler uses UTC, the same expression could mean 18:00 in Korea. Match the tool’s time zone to your real scheduler. In regions using daylight saving, a local time may be missing or repeated on transition days; inspect runs around those dates.

Example input

Details that matter

Format and meaning

Use five-field Unix Cron: minute, hour, day of month, month, weekday. Seconds and Quartz syntax are not supported.

Using it correctly

When both day-of-month and weekday are restricted, either matching field selects a day.

Common pitfalls

This tool calculates schedules; it does not schedule or execute jobs.

Supported scope and limits

Next 10 runs; numeric fields and *, /, -, , syntax

Split inputs that exceed the limit. If a format or algorithm is unsupported, choose a tool that matches your requirements instead of silently changing the format.
