How it works

What you need

• Cron expression (five fields)

What you get

• Next run
• Copy or save the result

Good to know

Standard five-field cron as used by Unix cron. When both day of month and day of week are restricted, a day matching either one runs. Next runs use your device's clock and time zone; your server may use a different zone. Seconds, years and special characters such as L, W, # and ? are not supported.
