24-hour time, you just subtract like normal maths, beta. From 9:20 to 13:05, duration is 3 hours 45 minutes. But I tell you, my own life... I calculate night-shift hours staring at the clock, and this numb wrist now makes even holding a pen to add time feel like a long calculation. So for me, the real maths is how many hours until my daughter’s voice note.
