AUTOMATION TOOL / 007

Cron expression builder.

Construct and verify a five-field cron schedule, understand what it means, and see exactly when it runs next.

BUILD THE SCHEDULE

This target supports CRON_TZ, so the expression stays in UTC and remains daylight-saving aware on the UTC server.

IMPLEMENTATION NOTE

Cron syntax and day-of-month/day-of-week behavior can vary between platforms. Confirm the expression against the scheduler that will actually run it. Traditional cron commonly evaluates day-of-month and day-of-week with OR behavior when both are restricted.
