Ever need to figure out what time it will be later for scheduling a call, setting a reminder, or just plain curiosity? It happens to everyone.
This article breaks down the ways you can figure out exactly what time it will be 18 hours from now, including doing the math yourself and using handy online tools.
How to calculate the time 18 hours from now
If you want to figure out what time it will be 18 hours from now, you can use a simple formula: T2 = T1 + 18. In this formula, T1 is the current time, and T2 is the time 18 hours from now. This is simple addition, but you’ll need to pay attention to the time format and whether adding 18 hours rolls you over into the next day.
For example, if it’s 2:00 PM now, then T2 = 2 + 18 = 20:00, or 8:00 PM.
Handling date rollovers
If adding 18 hours pushes you past midnight, you’ll need to subtract 24 hours from the total to get the correct time for the next day.
Let’s say it’s 10:00 AM right now. Adding 18 hours gets you to 28:00. If you subtract 24, you get 4:00 AM the next day. So, 18 hours from 10:00 AM today is 4:00 AM tomorrow.
It’s important to note the date change so you don’t get mixed up about when the event is happening.
