Your alarms
No alarms are set.
Not a system alarm. It cannot wake a closed or sleeping device. Background tab throttling, muted audio, or browser suspension can delay or silence it. Use a device alarm for important reminders. A repeated local time follows the browser's daylight-saving rules. Alarms stay in this browser only.
