How to Write Time in English for Academic Papers: Hours, Minutes, and Seconds

When writing an academic paper, it's essential to use clear and concise language, especially when expressing time. Here's how to write time involving hours, minutes, and seconds in English for your academic papers:

Formal Expression (24-hour clock):

• Use numerals separated by colons.* Example: 13:20:05

Formal Expression (12-hour clock):

• Use numerals separated by colons.* Add 'AM' or 'PM' to indicate morning or afternoon/evening.* Example: 1:20:05 PM

Therefore, 13:20:05 can be written as '13:20:05' or '1:20:05 PM' in your English academic papers.
