If you would like to set up a one-time cronjob, i.e. cronjob that runs at a specific time once and never repeats, you can follow these instructions:
- Click Add a cron job or Edit existing cronjob
- Enter URL to your cron script.
- At When to call field, click Exact time button
- Select the exact time for Minute, Hour, Day, Month, and Year fields. Remember to select all weekdays value (they're all selected by default) as well as select desired Timezone value.
For example, if you want your cronjob to run only once at 5:00 AM, Feb 14, 2018, select Minute: 0, Hour: 5, Day: 14, Month: 2, Year: 2018.
- Click Save changes.
And that's it. You can click on the time pattern field e.g. 0 5 14 2 * 2018 in the example above, and it'll show the next execution time so you can confirm the time settings are correct.
