How to Calculate Hours & Time Duration

⏱️ Time Duration Calculation

To calculate duration between two times: subtract start time from end time, then subtract break time.

Example: Start 9:00 AM, End 5:00 PM, Break 60 min = 7 work hours

➕ Adding / ➖ Subtracting Time

Total = (H1±H2) + (M1±M2)/60 + (S1±S2)/3600

Example: 2h30 + 1h45 = 4h15 | 5h00 - 2h30 = 2h30

🔄 Converting Time to Decimal

Decimal Hours = Hours + Minutes/60 + Seconds/3600
