Frequently asked questions

What does the cron expression "0 6 * * *" mean?

"0 6 * * *" is a Unix cron expression that means: At 06:00 AM. It contains 5 fields — Minute (0), Hour (6), Day of Month (*), Month (*), Day of Week (*) — and works in any scheduler that accepts the Unix cron format.

How does "0 6 * * *" behave in UTC versus local time?

The classic cron daemon interprets every field in the machine's local timezone (from /etc/timezone or the TZ environment variable). If the server runs in UTC the schedule fires in UTC; otherwise shift the hours accordingly. Modern cronie also supports CRON_TZ to pin a single job to UTC.

What happens if the machine is offline when "0 6 * * *" is due?

Classic cron does not catch up missed runs: if the server is down at the fire time, that execution is skipped until the next match. Guard the command with an idempotency check, or use anacron or a scheduler with missed-run handling when catch-up behavior matters.

About the “0 6 * * *” schedule

0 6 * * * is the Unix cron way to say “At 06:00 AM”. The simulator above evaluates it entirely in your browser — the timeline, the next-run table, and the timezone switcher all run client-side, so you can paste production schedules without them ever leaving your machine.

Every page in this directory follows the same structure: a plain-English translation, a per-field breakdown, platform-specific snippets, and a timezone-aware simulator. Move between the related intervals below to compare dialects, and validate one final time in the simulator with your own timezone before shipping.
