Check a schedule to see what it means and when it runs next.
How to read cron
Five fields: minute (0–59), hour (0–23), day of month (1–31), month (1–12), day of week (0–7; 0 and 7 mean Sunday). A star matches any value, a comma lists values, a dash defines a range, and a slash sets a step within a field.
For example, */15 * * * * runs at minutes 00, 15, 30 and 45 of every hour. */40 runs at 00 and 40: it is not a continuous 40-minute interval.
What the checker covers
This tool accepts five-field Unix cron. Seconds, Quartz, @reboot, H, L and # are outside its supported syntax. UTC offsets change during daylight saving transitions; skipped or repeated local hours may be handled differently by your scheduler. Check its behavior separately.
A valid schedule does not prove that the command ran. Tickwatch waits for job signals and alerts on missed runs, failures or excessive duration.
