# Schedule a task for a Duaer digital employee

In Duaer, a digital employee task can run hourly, daily, weekly, monthly, or on a cron expression. A custom cron shows a readable sentence and the next run time.
## Add a schedule

1. Open the digital employee.
2. Under Schedules, select Add schedule.
3. Enter a name and the task objective.
4. Under Schedule, pick a frequency: Hourly, Daily, Weekly, Monthly, or Custom (cron).
5. Pick a timezone. The list is the same one digital organization settings use. Save.

## A readable line for a custom cron <a href="#custom-cron" id="custom-cron"></a>

When the frequency is Custom (cron) and the expression is valid, Duaer shows a sentence next to the next run time, for example every day at 9:00 AM. The summary looks like “readable sentence · Next execution …”.

An invalid expression shows “This schedule isn't valid”, hides the sentence, and cannot be saved. There is no separate switch. When an existing task is paused, the summary says execution is paused and does not pretend a next run is coming.
## Questions

### Where does Duaer show the cron sentence for a digital employee?

On the task, set Schedule to Custom (cron). When the expression is valid, the sentence appears beside the next run time.

### What happens with an invalid cron in Duaer?

The form says the schedule is not valid, hides the readable sentence, and does not save the task.
