Why does my S5 beep every hour on the :07 and :31 minutes.

[AC Question]

This just started a few days ago. Every hour during the :07 and :31 minutes on my phone, there is a beep like no other notification I have. It doesn't happen right when the clock changes to the minute stated, but during that minute. NFC is off, and I can't see any notification it could be.

Help!
