Step 1
On the My calendars page, select a calendar you wish disable alarms for.
Click Edit.
How do I disable alarms?
Alarms can be disabled either by having the iOS Calendar application remove them, or by disabling them at WebCal.Guru. This process shows how they are disabled from the subscription at WebCal.Guru.
Note that disabling the alarms can be done with any device.
Step 2
Click the tab Alarms and set both alarm settings to None.
Step 3
Click Save.
The new settings take effect the next time your application downloads the calendar data, usually within a day or so.
