Ever needed to know what time it was several hours ago? It’s a more common question than you might think!
This article explains how to figure out what time it was 13 hours ago, whether you want to do the math yourself or use an online tool. So, let’s get started!
How to calculate time in the past
The principle is simple. If it’s 3:00 p.m. now, then two hours ago it was 1:00 p.m. You’re just subtracting the hours from the present time.
But what if you need to subtract so many hours that you end up in the previous day? That’s when things get a little trickier, but still manageable.
With the 24-hour clock system, the hours count up from 0 to 23. So, if you subtract too many hours, you simply loop back around and start counting from 23.

How to calculate 13 hours ago
Let’s say it’s 8:00 PM right now. To figure out what time it was 13 hours ago, you’d subtract 13 hours from 8:00 PM. That would be 7:00 AM today.
But what if it’s 6:00 AM now? Subtracting 13 hours means going back a day. In that case, 13 hours before 6:00 AM would be 5:00 PM yesterday.
The most important thing is to make sure you’re keeping track of AM and PM correctly!
