Before you start
A written task can still be missed when it has no due date or useful reminder.
Open the task for editing
In Tasks, tap Sign the school trip form. Check the description, assigned person and current due date, then choose Edit.

Choose the due date
Choose Today, Tomorrow or Date. The example uses 21 September 2026; if it is already selected, keep it. This Android form does not offer a separate due-time field.

Choose reminders and lead times
Open More settings and enable Reminders. Tap Remind Before Due to expand the options, scrolling if needed. Select 1h and 1d for one hour and one day before the due date. Leave Repeat reminders on No repeat if you only want those lead times.

Save and check the settings
Tap Done, then Save in the main form. Reopen the task with Edit. Check its date, assigned person and saved lead times in the More settings summary.

All done
Open the task, choose Edit and set its date. In More settings, enable Reminders and expand Remind Before Due to choose lead times. Use Done, then Save in the main form to keep the settings.
