Trello: How do I change the due date time format to 24h?

fmjansen September 14, 2018

When setting a due date, the time is displayed in the 12h format (i.e. using AM and PM; shown in screenshot). How do I change this to the 24h format?

Hi @fmjansen


you can have the time displayed as 24h format by changing the language from English (US) to English (UK). This will also change the way dates are displayed, but if you're fine with that it will achieve what you want.


Let me know if this helps,

Ooh, even better! I didn’t even notice the date format before, but this is what I wanted. Thanks!

I have Russian set as my language, but the time is in 12h format. We use 24h format. Please change the time format for Russian to 24h or allow to customize the time/date format.

It seems a bit inflexible not being able to change the date format independently of the language. I'm sure there are plenty of US English people who'd prefer a yyyy-mm-dd date format, or Danish people who'd prefer the first day of the week being Monday.

I don't understand why there aren't more people complaining about this, it's an impediment to productivity to keep changing from AM to PM every time

Log out and back in again, and then you'll see the change.

TL;DR - Solution as of 2023 July 26 


  1. Click on Profile Picture > Manage Account
  2. In the Atlassian Acount page, select Account Preferences
  3. Change language to English (UK)
  4. Log out and log in

As this was already covered in previous replies above, I'll repeat that this is not a solution. It's a work-around.

Language should work independently from the time format.

Yeah, but it works. You can complain about the issue or you can just fix it. 

I repeated because there are still unaswered replies to threads stating that this is not working when it clearly do.

Jan Frederiksen July 26, 2023

Fair enough.

I was reacting mostly to the fact that this is still an actual issue (with or without a work-around available) from a leading company. And it rubs me the wrong way to call it a solution :-)

But thank you for the update, it's always nice when posts like these are followed up on.

I agree with Jan. I'm perplexed that a company like Atlassian cuts corners like this. Don't they want to be the perfect product? You really can't have it like this..
