Alarm going off without setting

[Android Central Question]

My phone alarm goes off in the night somewhere between 3 am to 5 am. I have deleted all my alarms related to this time period. My phone automatically creates an alarm and then it goes off. I do not have this alarm set to go off. Please help with any idea to make it stop. The alarm has annoyed me completely. I am not able to sleep properly. This is really getting on my nerves.
