Trying to figure out how long until 1:20 PM? Glance at your clock right now and count forward to 1:20 PM. If it is still morning or early afternoon, you subtract your current time from 1:20 PM. If 1:20 PM has already gone by today, the countdown points to 1:20 PM tomorrow instead.
People time this moment for all sorts of reasons: a lunch meeting, a school bell, a pickup, a live stream, or just curiosity about how much of the workday is left. This guide gives you a live countdown for your own clock, a full chart covering every hour of the day, and a calculator you can set to any starting time.
Quick answer
Right now it is your current time.
Time left until 1:20 PM: counting down live
Rule of thumb: if it’s before 1:20 PM, subtract your time from 1:20 PM. If it’s already past, add the remaining hours to midnight plus 1 hour 20 minutes for tomorrow.
- 1:20 PM equals 13:20 on the 24-hour clock and 1320 in military time.
- 1:20 PM sits 800 minutes (48,000 seconds) after midnight.
- If 1:20 PM has already passed today, the next one is exactly 24 hours after the last one, on tomorrow’s date.
- The countdown keeps shrinking every second, so it is only accurate at the exact moment you read it.
What Does 1:20 PM Mean?
1:20 PM sits in the early afternoon, twenty minutes after one o’clock. It falls between the lunch hour and mid-afternoon, a common slot for a short meeting, a class period or a quick errand.
Switch to the 24-hour clock and that same moment reads 13:20. Drop the colon for four-digit notation and you get 1320. Because it carries a PM label, 1:20 PM always sits twelve hours away from 1:20 AM, which lands in the dead of night.
| Format | Value |
|---|---|
| 12-hour clock | 1:20 PM |
| 24-hour clock | 13:20 |
| Military time | 1320 |
| Part of day | Early afternoon |
| Minutes after midnight | 800 |
| Minutes after 1:00 PM | 20 |
How Long Until 1:20 PM?
The wait to 1:20 PM shrinks all morning and shoots back up the moment the clock ticks past it. Here is what the countdown looks like from a handful of odd, everyday starting points:
| Current time | Time until 1:20 PM |
|---|---|
| 7:15 AM | 6 hours 5 minutes |
| 8:45 AM | 4 hours 35 minutes |
| 10:15 AM | 3 hours 5 minutes |
| 11:35 AM | 1 hour 45 minutes |
| 12:15 PM | 1 hour 5 minutes |
| 12:55 PM | 25 minutes |
| 1:08 PM | 12 minutes |
| 1:20 PM | 0 minutes — it’s now |
At exactly 1:20 PM the countdown bottoms out at zero. One tick later, today’s target is gone, and the timer resets to run toward 1:20 PM tomorrow instead.
How Do You Calculate the Time Until 1:20 PM?
You don’t need an app for this. Look at the current time, then work out how far it sits from 1:20 PM in two short hops: to the top of the hour, then on to 1:20.
Scenario 1 — Starting at 8:05 AM
Target: 1:20 PM. From 8:05 AM to 1:00 PM is 4 hours 55 minutes. From 1:00 PM to 1:20 PM is 20 more minutes. Add them: 4 hours 55 minutes + 20 minutes = 5 hours 15 minutes until 1:20 PM.
Scenario 2 — Starting at 11:50 AM
From 11:50 AM to noon is 10 minutes. From noon to 1:20 PM is 1 hour 20 minutes. Together that is 1 hour 30 minutes until 1:20 PM.
Scenario 3 — Starting at 1:16 PM
Both times share the same hour, so just subtract the minutes: 20 − 16 = 4 minutes until 1:20 PM.
Scenario 4 — Starting at 5:40 PM
1:20 PM has already gone by. From 5:40 PM to midnight is 6 hours 20 minutes. From midnight to 1:20 PM tomorrow is 13 hours 20 minutes. Total: 6 hours 20 minutes + 13 hours 20 minutes = 19 hours 40 minutes until the next 1:20 PM.
How Many Minutes Until 1:20 PM?
Since 1:20 PM is 800 minutes after midnight, you can find the remaining minutes by converting the current time into minutes after midnight too, then subtracting.
Take 12:40 PM as an example. That is 12 hours 40 minutes after midnight, or (12 × 60) + 40 = 760 minutes after midnight. Subtract that from 800: 800 − 760 = 40 minutes until 1:20 PM.
This trick works for any starting time and avoids fumbling with AM and PM, since every minute-after-midnight value is a plain, growing number.
How Many Seconds Until 1:20 PM?
Multiply the remaining minutes by 60 to get seconds. Using the 40-minute example above: 40 × 60 = 2,400 seconds until 1:20 PM.
The second count changes every single second, of course, which is why a live page like this one is more useful than a printed number — it recalculates the instant you look at it.

1:20 PM in 24-Hour Time
Converting 1:20 PM to the 24-hour clock takes one small step. Since the hour is 1 and the period is PM, add 12: 1 + 12 = 13. The minutes never change.
1:20 PM → add 12 to the hour → 13:20
That gives you 13:20, the format you’ll spot on timetables, boarding passes and most schedules outside the US.
What Is 1:20 PM in Military Time?
Strip the colon from 13:20 and pad it to four digits, and you land on 1320, read aloud as “thirteen twenty.”
| Standard time | 24-hour time | Military time |
|---|---|---|
| 1:00 PM | 13:00 | 1300 |
| 1:10 PM | 13:10 | 1310 |

| 2:00 PM | 14:00 | 1400 |
1:20 AM vs. 1:20 PM
Same numbers, two completely different moments. 1:20 AM sits deep in the night, while 1:20 PM sits in the early afternoon, a full twelve hours apart.

| 11:00 PM | 23:00 | 14h 20m |
Notice the pattern: the minutes portion of the wait is always 20, because the target itself lands 20 minutes past the hour. Once you spot that, you only need to track the hours.

What If 1:20 PM Has Already Passed?
If the clock reads later than 1:20 PM, today’s target is behind you, and the countdown quietly switches to tomorrow’s 1:20 PM.
Say it is 6:50 PM. From 6:50 PM to midnight is 5 hours 10 minutes. From midnight to 1:20 PM is 13 hours 20 minutes. Add them: 5 hours 10 minutes + 13 hours 20 minutes = 18 hours 30 minutes until the next 1:20 PM.
This next-day approach works no matter how far past 1:20 PM you are, even if it is 11:59 PM.
Why Use a Countdown to 1:20 PM?
A running countdown turns a fixed clock time into something you feel, not just read. People lean on a 1:20 PM countdown for things like:
- Afternoon meetings or client calls
- School or college afternoon sessions
- Shift changes and break schedules
- Lunch pickups or carpool times
- Live webinars or streamed events
- Appointment reminders
- Cooking or baking timers set for a specific clock time
- Deadline reminders for online forms
A countdown matters most when the exact gap changes your plans, such as deciding whether there is time for one more task before 1:20 PM arrives.

Common Mistakes When Calculating Until 1:20 PM
Mixing Up AM and PM
1:20 AM is the middle of the night, while 1:20 PM is early afternoon. Always double-check the label before you start subtracting.
Writing 0120 Instead of 1320
0120 is military time for 1:20 AM. The afternoon version is 1320, not 0120.
Forgetting to Add 12
When you convert 1:20 PM to 24-hour time, the hour becomes 13, not 1. Skipping the “add 12” step is the most common slip.
Counting the Wrong Direction After the Target Passes
Once 1:20 PM has gone by, count forward to tomorrow’s 1:20 PM, not backward to an earlier one.
Changing the Minutes by Mistake
The 20 minutes stay fixed through every conversion. If your converted time shows different minutes, recheck your math.
Forgetting the Date Rolls Over
After 1:20 PM passes, the next occurrence belongs to the following calendar day, which matters for reminders and logs.
Frequently Asked Questions
How long until 1:20 PM?
It depends on your current time. If it is earlier than 1:20 PM, subtract your time from the target. If it has already passed, the wait runs to 1:20 PM tomorrow. The live box at the top of this page shows the exact countdown for your clock.
What is 1:20 PM in 24-hour time?
Switching to the 24-hour clock, that moment becomes 13:20.
What is 1:20 PM in military time?
In four-digit military notation, that same instant is shown as 1320.
What does 1320 mean in regular time?
The code 1320 refers to 1:20 PM back on the standard 12-hour clock.
How many minutes after midnight does 1:20 PM fall?
1:20 PM is 800 minutes after midnight (13 hours × 60 + 20 minutes).
How many seconds are there in 20 minutes?
Multiply 20 by 60 and you get 1,200 seconds — the same span, just measured in a smaller unit.
What happens once 1:20 PM has already gone by today?
The target simply rolls to 1:20 PM tomorrow, exactly 24 hours after the one that passed.
Does 13:20 mean the same thing as 1:20 PM?
Yes, 13:20 and 1:20 PM name the identical instant — just written in two different clock formats.

1:20 AM converts to 0120 — a separate four-digit code from 1:20 PM’s 1320.
How can you work out the time left until 1:20 PM?
Compare your current time with 1:20 PM and find the gap in hours and minutes. If the target already passed today, measure the gap to tomorrow’s 1:20 PM instead.
Can I set a phone alarm for a countdown to 1:20 PM?
Yes. Most phone clock apps let you set an alarm for a specific clock time, so you can enter 1:20 PM directly instead of calculating the remaining minutes yourself.
Why does the countdown number change every second on this page?
Because the countdown measures the gap between right now and 1:20 PM, and “right now” moves forward every second, so the remaining time keeps shrinking.
Conclusion
Working out how long until 1:20 PM comes down to one comparison: is it before or after 1:20 PM right now? Before it, subtract your time from the target. After it, add the hours left in the day to 1 hour 20 minutes for tomorrow.
Remember that 1:20 PM = 13:20 = 1320, and it sits 800 minutes (48,000 seconds) after midnight. For an answer that updates itself, use the live box at the top of this page or the calculator above.
