Full operation shown in minutes (most reliable).
Step 1: Convert start time to minutes
| Start time | 8 PM (20:00) |
|---|---|
| Start minutes | 1200 minutes after 00:00 |
| Add minutes | 23 × 60 = 1380 minutes |
| Total minutes | 2580 |
Step 2: Split into days + time-of-day
| Minutes per day | 1440 |
|---|---|
| Days added | 1 (because 2580 ÷ 1440) |
| Remainder minutes | 1140 (2580 mod 1440) |
| Result time | 7 PM (19:00) |
Final: 23 hours after 8 PM is 7 PM.
