    Is your cron job actually running?

    Add one line to the end of your job and Upwatch alerts you the moment a scheduled run is missed: heartbeat monitoring for backups, reports and scripts.

    Cron syntax in one minute

    A standard cron expression has five fields separated by spaces. A job runs whenever all of them match the current time:

    FieldAllowed valuesNotes
    Minute0–59
    Hour0–2324-hour clock
    Day of month1–31
    Month1–12 or JAN–DEC
    Day of week0–7 or SUN–SAT0 and 7 are both Sunday

    Special characters

    *Every value. * in the hour field means every hour.
    ,A list of values. 1,15 in day of month means the 1st and the 15th.
    -A range. 1-5 in day of week means Monday to Friday.
    /A step. */10 in minutes means every 10 minutes; 9-17/2 in hours means 9, 11, 13, 15 and 17.
    @dailyShortcuts: @yearly, @monthly, @weekly, @daily, @hourly and @reboot (once at startup).

    Good to know

    If both day of month and day of week are restricted, most cron implementations run the job when either matches. 0 0 1 * 1 runs on the 1st of the month and on every Monday. Cron uses the server's local timezone unless your system says otherwise, so check the UTC view above if your server runs in UTC.
