If there are date fields on your sheet, the Event Calendar on your user homepage lists up to 10 upcoming entries that are entered with date information as events.
Clicking the name of the event will take you to the form page of the related entry.
Clicking the Show calendar button will open a calendar report listed with these events.
You may make configurations to the events shown on the calendar by hovering on the event name and clicking on the gear icon next to it:
Hide this type of events: Hide the events that are from the same date field on that sheet.
Set a short name for this sheet: Set up a short display name for the sheet of the events that are from the same date field.
If you would like to change the field value of the Event shown on the calendar, you would need to configure the title field of your sheet.
