72 hours = 3 days = 4,320 minutes = 259,200 seconds
Divide hours by 24 to get days: 72 ÷ 24 = 3. So a "72-hour" deadline that starts on Monday at 9 AM ends on Thursday at 9 AM. In business days it can be longer: 72 hours starting Friday morning ends Monday morning, which most offices would count as one working day.
