Wondering how long until 1:20 PM? The exact answer depends on your current time. To find the remaining time, compare the current time with the target of 1:20 PM and calculate the difference in hours and minutes.
A countdown to 1:20 PM can be useful for appointments, classes, meetings, work schedules, lunch plans, reminders, or other daily activities. If 1:20 PM has already passed, the next target is 1:20 PM on the following day.
What Does 1:20 PM Mean?
1:20 PM is an afternoon time on the standard 12-hour clock. It means 20 minutes after 1 PM.
On a 24-hour clock, 1:20 PM is written as 13:20. In four-digit military-time notation, it is written as 1320.
| Time Format | 1:20 PM |
| 12-hour clock | 1:20 PM |
| 24-hour clock | 13:20 |
| Military time | 1320 |
| Time of day | Afternoon |
| Minutes after midnight | 800 |
| Minutes after 1 PM | 20 |
The AM or PM designation is important because 1:20 AM and 1:20 PM occur 12 hours apart.
How Long Until 1:20 PM?
The exact countdown to 1:20 PM changes throughout the day. If the current time is earlier than 1:20 PM, subtract the current time from the target.
Here are some common examples:
| Current Time | Time Until 1:20 PM |
| 9:00 AM | 4 hours 20 minutes |
| 10:00 AM | 3 hours 20 minutes |
| 11:00 AM | 2 hours 20 minutes |
| 12:00 PM | 1 hour 20 minutes |
| 12:30 PM | 50 minutes |
| 1:00 PM | 20 minutes |
| 1:05 PM | 15 minutes |
| 1:10 PM | 10 minutes |
| 1:15 PM | 5 minutes |
| 1:20 PM | 0 minutes |
At exactly 1:20 PM, the countdown reaches zero.
If the current time is later than 1:20 PM, today’s target has already passed, so you need to calculate the time remaining until 1:20 PM tomorrow.
How Do You Calculate the Time Until 1:20 PM?
Calculating the time difference manually is simple.
First, check the current time. Then subtract it from 1:20 PM if the target has not yet arrived.
Example 1: Current Time Is 10:00 AM
Target time: 1:20 PM
From 10:00 AM to 1:00 PM = 3 hours.
From 1:00 PM to 1:20 PM = 20 minutes.
Therefore:
3 hours + 20 minutes = 3 hours 20 minutes
So, if it is 10:00 AM, there are 3 hours and 20 minutes until 1:20 PM.
Example 2: Current Time Is 12:30 PM
The target is 1:20 PM.
From 12:30 PM to 1:00 PM = 30 minutes.
From 1:00 PM to 1:20 PM = 20 minutes.
Therefore:
30 + 20 = 50 minutes
There are 50 minutes until 1:20 PM.
Example 3: Current Time Is 1:10 PM
Both times are within the same hour, so subtract the minutes:
20 − 10 = 10 minutes
Therefore, there are 10 minutes until 1:20 PM.
Example 4: Current Time Is 2:00 PM
1:20 PM has already passed.
From 2:00 PM to midnight = 10 hours.
From midnight to 1:20 PM = 13 hours 20 minutes.
Total:
10 hours + 13 hours 20 minutes = 23 hours 20 minutes
So, at 2:00 PM, the next 1:20 PM is 23 hours and 20 minutes away.
How Many Minutes Until 1:20 PM?
Converting the target into total minutes is another useful way to calculate the time difference.
1:20 PM is 13 hours and 20 minutes after midnight.
13 hours × 60 = 780 minutes
780 + 20 = 800 minutes
Therefore, 1:20 PM is 800 minutes after midnight.
For example, at exactly 12:00 PM:
1:20 PM = 800 minutes after midnight
12:00 PM = 720 minutes after midnight
800 − 720 = 80 minutes
So, at noon, there are 80 minutes until 1:20 PM, which is 1 hour and 20 minutes.
How Many Seconds Until 1:20 PM?
There are 60 seconds in every minute.
Since 1:20 PM is 800 minutes after midnight:
800 × 60 = 48,000 seconds
Therefore, 1:20 PM occurs 48,000 seconds after midnight.
The actual number of seconds remaining until 1:20 PM depends on the current time and changes continuously.
For example, at exactly 1:00 PM, there are 20 minutes remaining:
20 × 60 = 1,200 seconds
So, at 1:00 PM, there are 1,200 seconds until 1:20 PM.
1:20 PM in 24-Hour Time
1:20 PM is 13:20 in the 24-hour clock.
To convert 1:20 PM:
- Identify the hour as 1.
- The time is PM, and the hour is not 12.
- Add 12 to the hour.
- 1 + 12 = 13.
- Keep the minutes unchanged at 20.
The result is:
1:20 PM = 13:20
The minutes remain the same during the conversion.
What Is 1:20 PM in Military Time?
In four-digit military-time notation, 1:20 PM is 1320.
The conversion is:
1:20 PM → 13:20 → 1320
It is commonly read as “thirteen twenty.”
| Standard Time | 24-Hour Time | Military Time |
| 1:00 PM | 13:00 | 1300 |
| 1:05 PM | 13:05 | 1305 |
| 1:10 PM | 13:10 | 1310 |
| 1:15 PM | 13:15 | 1315 |
| 1:20 PM | 13:20 | 1320 |
| 1:25 PM | 13:25 | 1325 |
| 1:30 PM | 13:30 | 1330 |
| 1:40 PM | 13:40 | 1340 |
| 1:50 PM | 13:50 | 1350 |
This format is useful when reading schedules, transportation timetables, workplace records, or other systems that use the 24-hour clock.

1:20 AM vs. 1:20 PM
The two times have the same hour and minute but occur at completely different parts of the day.
| Feature | 1:20 AM | 1:20 PM |
| Period | Early morning | Afternoon |
| 24-hour format | 01:20 | 13:20 |
| Military time | 0120 | 1320 |
| Minutes after midnight | 80 | 800 |
| Difference between them | 12 hours earlier | 12 hours later |
Remembering the AM/PM difference is essential when setting a countdown or scheduling an event.
How Far Is 1:20 PM From Other Common Times?
Knowing the difference from nearby times can help with quick mental calculations.
| Starting Time | Difference to 1:20 PM |
| 9:00 AM | 4 hours 20 minutes |
| 9:30 AM | 3 hours 50 minutes |
| 10:00 AM | 3 hours 20 minutes |
| 10:30 AM | 2 hours 50 minutes |
| 11:00 AM | 2 hours 20 minutes |
| 11:30 AM | 1 hour 50 minutes |
| 12:00 PM | 1 hour 20 minutes |
| 12:30 PM | 50 minutes |
| 1:00 PM | 20 minutes |
| 1:10 PM | 10 minutes |
| 1:15 PM | 5 minutes |
This quick reference makes it easy to estimate the countdown without doing a full calculation every time.
What If 1:20 PM Has Already Passed?
If the current time is later than 1:20 PM, today’s 1:20 PM has already occurred.
For example, if it is 4:00 PM, the next target is 1:20 PM tomorrow.
From 4:00 PM to midnight = 8 hours.
From midnight to 1:20 PM = 13 hours 20 minutes.
Therefore:
8 hours + 13 hours 20 minutes = 21 hours 20 minutes
So, at 4:00 PM, the next 1:20 PM is 21 hours and 20 minutes away.
The same next-day method works regardless of how much later the current time is.
Why Use a Countdown to 1:20 PM?
A countdown can help you stay aware of how much time remains before an important event.
You might use a 1:20 PM countdown for:
- Meetings and appointments
- School or college classes
- Work schedules
- Lunch or break times
- Travel plans
- Daily reminders
- Personal activities
- Online events
A countdown is especially useful when the exact number of hours and minutes matters rather than simply knowing the current time.

Common Mistakes When Calculating Until 1:20 PM
Several simple mistakes can produce the wrong countdown.
- Forgetting PM: 1:20 PM is an afternoon time, while 1:20 AM is early morning.
- Using 0120 instead of 1320: 0120 represents 1:20 AM, not 1:20 PM.
- Forgetting to add 12: When converting 1:20 PM to 24-hour time, 12 must be added to the hour.
- Counting backward after the target passes: If it is already after 1:20 PM, calculate toward tomorrow’s 1:20 PM.
- Changing the minutes during conversion: The 20 minutes remain unchanged when converting to 24-hour time.
- Ignoring the date: After 1:20 PM has passed, the next occurrence is on the following day.
Checking the AM/PM period first is the easiest way to avoid these errors.
Conclusion
Knowing how long until 1:20 PM is a straightforward time-difference calculation. If the current time is earlier than 1:20 PM, subtract it from the target. If 1:20 PM has already passed, calculate the time remaining until tomorrow’s 1:20 PM.
For quick reference, remember that 1:20 PM = 13:20 = 1320. It is 800 minutes after midnight, while the exact countdown changes continuously as the current time moves closer to the target.
