    Using a 3:00 PM alarm

    A afternoon alarm is useful as a reminder rather than a wake-up call — taking medication, leaving for a pickup, joining a call, or stopping work on time. Give it a label (e.g. "Pills" or "Leave now") so you know what it's for when it rings.

    Planning a nap instead? A 20-minute timer is the classic power nap; a 90-minute timer covers one full sleep cycle.

    3:00 PM is 15:00 in 24-hour time, or 1500 hours in military time.
