Time (12h AM/PM)
24 hour time format HH:MM
If you’re working with time formats, converting between the 12-hour clock (AM/PM) and the 24-hour clock (00:00-23:59) becomes essential. The 12-hour format uses AM (“ante meridiem” – before midday) and PM (“post meridiem” – after midday). The 24-hour format starts at midnight (00:00) and runs through the day to 23:59 before the next midnight.
🔄 How to Convert from 12-Hour to 24-Hour
Here’s the simple rule:
For times from 1:00 AM to 11:59 AM, the hour remains the same in 24-hour format.
12:00 AM (midnight) becomes 00:00.
12:00 PM (noon) remains 12:00.
For any time from 1:00 PM to 11:59 PM, add 12 to the hour to get the 24-hour equivalent.
Example: 3:00 PM + 12 = 15:00
Example: 9:45 PM + 12 = 21:45
🕰 Why This Matters
The 24-hour clock avoids ambiguity between morning and evening times—there is no need for AM or PM. This makes it widely used in travel timetables, hospitals, data logs, military and other professional settings. Understanding how to switch between formats ensures you can interpret schedules, logs and digital displays correctly.
Whether you’re filling out forms, reading transportation schedules, managing international meetings or using time-tracking software, this conversion gives you clarity and avoids mistakes.
