How many hours between 10:00 AM and 2:00 AM?

Answer: 16 hours

We convert both times into minutes from the start of the day, subtract, and if the result is negative we treat the end time as the next day (midnight crossing).

Readable form: 10:00 AM → 2:00 AM = 16 hours
End time is treated as the next day because it is earlier than the start time.

Detailed Math (Step-by-Step)

Full minute-based operation shown clearly.

Step 1: Convert both times to minutes

Start time 10:00 AM
Start in minutes 600 minutes from 00:00
End time 2:00 AM
End in minutes 120 minutes from 00:00
Minute formula: difference_minutes = end_minutes − start_minutes

Step 2: Subtract (and handle midnight crossing)

Raw subtraction 120 − 600 = -480
Midnight crossing Add 1440 minutes (24×60): -480 + 1440 = 960
Difference (minutes) 960 minutes
Convert to hours 960 ÷ 60 = 16 hours
Readable form: 16 hours
