Date field format does not match system settings

1Password has had problems with date formatting for input and display since v8 first came out years ago, with little progress in that time. They fix date related problems in one area, and introduce new issues elsewhere.

I don't know whether its the same for you, but for me, whilst entering a date, the format is mm/dd/yyyy but then when not editing, the same date switches to dd/mm/yyyy format as it should be for my locale.

I know dealing with dates can be complicated in programming in general, but this has been going on for years, and is a fundamental aspect of the app, yet remains unfixed after all this time.

They've even recently added an expiration date field to items in the beta, but this suffers from the same ancient date formatting bugs as other date fields. You'd think they'd fix the date formatting functionality first, before introducing new date related features that just highlight these bugs.

Hello @pepijnve! 👋

I'm sorry that 1Password for Mac doesn't match the date format that you have set for macOS itself when editing an item. This is a known issue that our development team is aware of and is working on a fix for. 

Keep an eye on our release notes which will mention a fix as soon as it is released: https://releases.1password.com/

I'm not sure why this is marked as solved as I live in a locale that uses DD-MM-YYYY; but I set my OS to YYYY-MM-DD (because that's the CORRECT way to format dates - I'm opinionated that way, but ISO8601 is a common way to deal with this). I really don't understand why I see dates formatted in ways that I don't want or use anywhere in my system.  Please prioritise fixing this,  it isn't just a preference but errors get made and then there are consequences. My child's passport application was held up because of this bug (month and date transposed led to secondary questioning). Again - this isn't a cutesy thing but a real operability bug. As a 10+ year customer I really really want to see this fixed. The whole world isn't using the same date system and that the ISO standard isn't working correctly is a bit of a shocker to me after all these years. Sorry that I'm venting; but this isn't just a preference - it causes people problems.

Yeah, this is really annoying, using the American format is really confusing and leads to actual issues (missed expirations and similar). Date format should follow Regional Settings i Windows or be possible to chose in Settings.

And also, it should not follow language. I speak Swedish but live in Finland so I want the Finnish date format (dd.mm.yyyy), not the Swedish (yyyy.mm.dd), but at least that is better than American.

this is still not working. Why is this marked as solved?
American format is so annoying, causing a lot of problems.

I am still seeing this as reported. As a power user an additional suggestion is that I would always prefer typing in a date in iso8601 format with flexible or absent separators over the interactive pop ups that force protracted interaction scrolling for (literally) years :).

@1P_Dave i can grab screen caps for the edit date format flip of you like. Just let me know

Same issue here, I’m glad there is a fix on the way. My details if it helps:

• macOS 15.5, 1Password macOS 8.10.78
• Date format set to DD/MM/YYYY
• I believe the computer language is set to English (UK), though either my browser or OS might have been English (US) when registering to 1Password years ago, which might have led to this issue.

I’m also encountering this for passports’ expiry fields, where getting this wrong isn’t an option. So it’d be great if in addition to showing the date in my expected format, there was a way to unambigously "double check" by seeing the month name spelled out, or the ISO 8601 formatted date.

@thibaudcolas, @muonzoo, @pepijnve, @bendap, @klindberg, and @snozdop 

Thank you for your patience. Our developers are testing a fix in the latest beta version of the 1Password desktop app. Would you mind temporary switching to the beta version to see if the fix resolves the issues that you're seeing:

• Install a beta release of the 1Password app

If you still see the issue with Beta 8.10.80-18 (or later) can you post screenshot of what you see in the 1Password app and your current operating system region/date settings?
