Ever need to quickly figure out what time it will be 8 hours from now? Whether you’re scheduling a meeting, setting a reminder, or just planning your day, it’s a common calculation.
This article will walk you through the easiest ways to determine what time it will be exactly 8 hours from now.
How to calculate what time it will be 8 hours from now
Calculating a future time is a simple task. Here’s how to do it.
Start with the current time
To know what time it will be 8 hours from now, you need to know what time it is right now. Seems obvious, but it’s the most important first step.
Add the hours
Add 8 to the “hour” part of the current time. So, if it’s 2:00 p.m. now, add 8 to 2.
The result is 10:00 p.m. Eight hours from 2:00 p.m. is 10:00 p.m.
AM/PM Considerations
Calculating a time that’s eight hours from now can get a little tricky when you cross over from AM to PM, or from one day to the next.
Understanding AM and PM
A quick refresher: AM stands for ante meridiem, which means “before noon” in Latin. PM stands for post meridiem, or “after noon.” So, AM refers to the time from midnight to noon, and PM is noon to midnight.
Adjusting for AM/PM Transitions
If adding eight hours pushes you past 12 o’clock, you’ll need to subtract 12 and switch from AM to PM, or vice versa. For instance, if it’s 8:00 PM now, adding eight hours gives you 16:00. Take away 12, and you get 4:00 AM.
Day Rollover
Don’t forget about the day rolling over when your calculation crosses midnight. If you add eight hours to 8:00 PM, it will be 4:00 AM the next day.
How do you convert to 24-hour time?
The 24-hour clock system, sometimes called “military time,” shows all 24 hours in a day using the numbers 00:00 to 23:59.
To convert from standard time to military time, add 12 to any PM hour. So, 3:00 PM becomes 15:00. All AM times stay the same.
Frequently Asked Questions
How many days is 99999 hours from now?
Okay, let’s break that down. There are 24 hours in a day. So, to find out how many days 99999 hours is, you’d divide 99999 by 24. That gives you approximately 4166.625 days. So, it’s a little over 4166 and a half days from now. That’s a long way off!
Is 7AM to 3PM 8 hours?
Yes, 7AM to 3PM is an 8-hour stretch. If you start counting at 7AM, then 8AM, 9AM, 10AM, 11AM, 12PM, 1PM, 2PM, and finally 3PM, you’ll see that you counted eight hours total. So, that classic 9-to-5 workday is more like a 7-to-3, right?
How much is 9 hours from now?
That depends on what time it is right now! If it’s noon, then 9 hours from now would be 9 PM. If it’s 6 PM, then 9 hours from now would be 3 AM the next day. Just add 9 to the current hour, and if you go past 12, remember to loop back around and add a “PM” or “AM” as needed. And don’t forget to factor in daylight savings time!
Putting It All Together
Calculating the time eight hours from now is as simple as adding eight hours to the current time. Remember to switch from AM to PM (or vice versa) if you cross the noon or midnight mark, and be aware of whether the date will change.
Being able to quickly figure out the time eight hours in the future can be useful in all sorts of situations.
