Hello 12Tania,

It's awesome to hear that you've upgraded to QuickBooks Desktop 2020. I hope you're enjoying all the new features the program has to offer. I'll include a link of what those are at the end of this response so you can take a look at them all.

Like with previous versions of the program, QuickBooks Desktop's date format is based on the date format of your computer. If you're not liking the date format you're seeing, check your Windows settings to make sure you have the one you want selected. Keep in mind that if you have the program installed on multiple computers that you'll want to make sure they're each using the same date format to keep things uniform.

That should get you on your way! Here's the article I mentioned: What's new in QuickBooks Desktop 2020

Enjoy the rest of your day!
