Why use a Cron Explainer?
Cron expressions like */15 8-18 * * 1-5 are powerful but notorious for being hard to read at a glance. Even experienced developers often need to double-check their logic to ensure scripts don't run at the wrong times.
This tool takes the guesswork out by breaking down the string into human-readable text and calculating exactly when it will execute next based on your local system time.
Features
- Plain English Translation: Automatically translates complex scheduling rules into understandable text.
- Next Executions Preview: Calculates the precise dates and times for the next 5 runs so you can verify it behaves as expected.
