Wondering how long until 1:20? The exact answer depends on your current time and whether you mean 1:20 AM or 1:20 PM. A countdown changes continuously as the clock moves closer to the target time.
In this guide, you will learn how to calculate the time remaining until 1:20, convert 1:20 AM and 1:20 PM into 24-hour and military time, and understand the difference between the two. You can also use the simple examples and tables below to calculate the countdown quickly.
How Long Until 1:20 AM?
The time until 1:20 AM depends on the current time. If it is before 1:20 AM, count forward to that time. If 1:20 AM has already passed, the next 1:20 AM will be tomorrow.
For example:
| Current Time | Time Until 1:20 AM |
| 12:00 AM | 1 hour 20 minutes |
| 12:30 AM | 50 minutes |
| 1:00 AM | 20 minutes |
| 1:10 AM | 10 minutes |
| 1:20 AM | 0 minutes |
| 2:00 AM | 23 hours 20 minutes until tomorrow |
This is why a live countdown is useful: the exact hours, minutes, and seconds depend on the current local time.
How Long Until 1:20 PM?
1:20 PM is 13:20 on the 24-hour clock. To find the remaining time, compare the current time with 1:20 PM.
For example:
| Current Time | Time Until 1:20 PM |
| 11:00 AM | 2 hours 20 minutes |
| 12:00 PM | 1 hour 20 minutes |
| 12:30 PM | 50 minutes |
| 1:00 PM | 20 minutes |
| 1:10 PM | 10 minutes |
| 1:20 PM | 0 minutes |
| 2:00 PM | 23 hours 20 minutes until tomorrow |
If the current time is after 1:20 PM, the countdown normally points to the next day’s 1:20 PM.
What Time Is 1:20 in 24-Hour Format?
There are two possible 24-hour representations because 1:20 can refer to either AM or PM.
| 12-Hour Time | 24-Hour Format | Military Time |
| 1:20 AM | 01:20 | 0120 |
| 1:20 PM | 13:20 | 1320 |
The important difference is the hour. 1:20 AM becomes 01:20, while 1:20 PM becomes 13:20.
The minutes remain 20 in both conversions.
What Is 1:20 AM in Military Time?
1:20 AM in military time is 0120.
In standard 24-hour format, it is written as 01:20. The leading zero is used because the hour is between midnight and 9:59 AM.
The conversion is simple:
1:20 AM → 01:20 → 0120
This represents 1 hour and 20 minutes after midnight.
What Is 1:20 PM in Military Time?
1:20 PM in military time is 1320.
In 24-hour clock notation, it is 13:20. For afternoon times from 1:00 PM through 11:59 PM, add 12 to the hour.
For 1:20 PM:
1 + 12 = 13
Therefore:
1:20 PM → 13:20 → 1320
How Many Hours Until 1:20?
The number of hours until 1:20 changes depending on the current time.
If you are counting toward 1:20 PM, some simple examples are:
- 10:20 AM → 3 hours
- 11:20 AM → 2 hours
- 12:20 PM → 1 hour
- 12:50 PM → 30 minutes
- 1:00 PM → 20 minutes
The same method works for 1:20 AM. Always identify the correct AM or PM period before calculating.
How Many Minutes Until 1:20?
To calculate minutes until 1:20, convert both times into minutes and subtract.
For example, from 12:00 PM to 1:20 PM:
- 12:00 PM = 720 minutes after midnight
- 1:20 PM = 800 minutes after midnight
- 800 − 720 = 80 minutes
So, there are 80 minutes from 12:00 PM until 1:20 PM.
Another example is 1:00 PM to 1:20 PM:
20 minutes
This simple conversion is useful when a countdown is displayed only in total minutes.
How Many Seconds Until 1:20?
You can convert the remaining time into seconds by multiplying minutes by 60.
For example, 20 minutes equals:
20 × 60 = 1,200 seconds
Therefore, if it is exactly 1:00 PM, there are 1,200 seconds until 1:20 PM.
A live countdown may show a slightly different number because seconds continue passing while you are viewing it.
How to Calculate How Long Until 1:20
You can calculate the countdown manually in a few steps.
- Check your current local time.
- Decide whether you mean 1:20 AM or 1:20 PM.
- Compare the current time with the target.
- Subtract the current time from 1:20.
- If 1:20 has already passed, calculate toward the next day’s 1:20.
For example, suppose the current time is 12:35 PM and your target is 1:20 PM.
From 12:35 PM to 1:00 PM = 25 minutes.
From 1:00 PM to 1:20 PM = 20 minutes.
So:
25 + 20 = 45 minutes
There are 45 minutes until 1:20 PM.

What If 1:20 Has Already Passed?
If your target time has already passed, the next occurrence is usually tomorrow.
For example, if it is 3:00 PM today, today’s 1:20 PM has already passed. You therefore count forward to 1:20 PM tomorrow.
The same rule applies to 1:20 AM. If it is 5:00 AM, the next 1:20 AM occurs the following day.
This prevents a negative countdown and gives you the correct waiting period.
1:20 AM vs. 1:20 PM
The difference between these two times is important because they occur 12 hours apart.
| Feature | 1:20 AM | 1:20 PM |
| Time of day | Early morning | Afternoon |
| 24-hour format | 01:20 | 13:20 |
| Military time | 0120 | 1320 |
| Minutes after midnight | 80 | 800 |
| 12-hour notation | 1:20 AM | 1:20 PM |
If someone simply says “1:20”, the context may be necessary to determine whether they mean morning or afternoon.
Is 1:20 AM Morning?
Yes. 1:20 AM is early morning.
AM covers the period from midnight through the morning until just before noon. Since 1:20 AM occurs shortly after midnight, it is generally considered early morning.
Is 1:20 PM Afternoon?
Yes. 1:20 PM is afternoon.
PM begins at noon and continues until midnight. Therefore, 1:20 PM is an afternoon time, shortly after noon.
Why Does the Time Zone Matter?
A countdown to 1:20 depends on the time zone in which the countdown is being calculated.
For example, 1:20 PM in Pakistan does not occur at the same moment as 1:20 PM in New York or London. Each location has its own local clock.
When using an online countdown, check that the tool is using your intended local time zone. Otherwise, the displayed remaining time may not match the clock you are looking at.

Common Mistakes When Calculating Until 1:20
A few simple mistakes can produce an incorrect countdown:
- Forgetting to specify AM or PM.
- Treating 1:20 PM as 01:20 instead of 13:20.
- Forgetting that 12:00 AM is midnight.
- Forgetting that 12:00 PM is noon.
- Continuing to count toward today’s target after it has already passed.
- Ignoring the local time zone.
- Rounding a live countdown instead of accounting for minutes and seconds.
Using the 24-hour clock can make calculations easier because AM and PM confusion is removed.
How Does a 1:20 Countdown Timer Work?
A countdown timer compares the current local time with the selected target time. It then displays the difference in hours, minutes, and seconds.
For example, if the target is 1:20 PM and the current time is 1:00 PM, the timer begins at approximately 20 minutes. As every second passes, the remaining value decreases.
When the countdown reaches zero, the target time has arrived.
Conclusion
Knowing how long until 1:20 is simple once you identify whether the target is 1:20 AM or 1:20 PM. The exact countdown changes with the current time, while the standard conversions remain fixed: 1:20 AM is 01:20 or 0120, and 1:20 PM is 13:20 or 1320.
For accurate results, always check your current local time, account for your time zone, and remember that a target that has already passed will normally refer to the next day’s occurrence.
