Working out time differences is something we all do every day. Whether it’s calculating travel times or setting reminders, we’re constantly thinking about where we are in time and space. So, if you’re wondering “18 hours from now is what time?”, this article will show you how to figure it out.
The basics of time calculation
Calculating time changes is fairly straightforward, but it’s important to understand a few basic concepts.
AM and PM
Most of us are familiar with the terms AM and PM, but you may not know what they stand for. AM stands for ante meridiem, which means “before noon” in Latin. AM refers to the time between midnight and noon.
PM stands for post meridiem, which means “after noon” in Latin. PM refers to the time between noon and midnight.
12-hour vs. 24-hour clock
The 12-hour clock uses the numbers 1 through 12 to designate each hour of the day. To differentiate between morning and afternoon, we use AM and PM.
The 24-hour clock, sometimes called military time, uses the numbers 00 to 23 to designate each hour of the day. For example, 2 PM is 14:00 hours in the 24-hour clock system. The 24-hour clock eliminates any ambiguity about AM or PM.
How to calculate the time 18 hours from now
Okay, so you need to figure out what time it will be 18 hours from now. Here’s how to do it:
- Figure out what time it is right now.
- Add 18 hours to the current hour.
- If the hour you end up with is higher than 12, subtract 12 from it. Then, switch AM to PM or PM to AM. (That’s because once you hit 13:00 in military time, you loop back around to 1:00 PM.)
- If you go past midnight, remember that the date will change to the next day.
Let’s try a couple of examples.
If it’s 8:00 AM right now, what time will it be 18 hours from now? 8:00 AM plus 18 hours equals 2:00 AM the next day.
Here’s another one: If it’s 8:00 PM now, what time will it be in 18 hours? 8:00 PM plus 18 hours is 2:00 PM the next day.
Tips for Calculating Time
When figuring out what time it will be 18 hours from now, keep the following in mind:
- Start with the right time. An inaccurate starting time will throw off the entire calculation.
- Factor in time zones. If you’re trying to calculate the time in another geographical location, you’ll need to adjust for the time difference.
- Use online calculators. There are many free and easy-to-use time calculators available online. These tools can quickly provide the answer you need.
