Frequently asked questions
Quick answers for developers landing here from search.
What cron format do you support?
This explainer works with standard five-field crons (minute, hour, day of month, month, day of week). Advanced syntax like year fields isn't currently supported.
How are next run times calculated?
We simulate the schedule in UTC and shift results to the timezone you choose, listing the next five runs so you can double-check deployments.
Does the tool execute the cron?
No. It simply analyses the expression locally, so you can share the explanation without running anything on a server.
