Full operation shown in minutes (most reliable).
Step 1: Convert start time to minutes
| Start time | 1 AM (01:00) |
|---|---|
| Start minutes | 60 minutes after 00:00 |
| Add minutes | 48 × 60 = 2880 minutes |
| Total minutes | 2940 |
Step 2: Split into days + time-of-day
| Minutes per day | 1440 |
|---|---|
| Days added | 2 (because 2940 ÷ 1440) |
| Remainder minutes | 60 (2940 mod 1440) |
| Result time | 1 AM (01:00) |
Final: 48 hours after 1 AM is 1 AM.
