Short answer: Take the current time, subtract 1 hour, then subtract 30 minutes. If the minutes go negative, borrow an hour and add 60.
Quick Example
If it’s 2:15 PM now, 1 hour and 30 minutes ago it was 12:45 PM.
| Current Time | 1 Hour 30 Minutes Ago |
|---|---|
| 9:00 AM | 7:30 AM |
| 12:15 PM | 10:45 AM |
| 1:00 AM | 11:30 PM (previous day) |
Same Question, Different Words
“1 hour 30 minutes ago” and “90 minutes ago” mean the same thing. Both subtract the same span from your current time.
Crossing Midnight or AM/PM
When the current time is early morning, subtracting 90 minutes can push you into yesterday. For example, 12:20 AM minus 90 minutes lands at 10:50 PM the day before. Watch for that date change.
