Hi there, 

QuickBooks Online helps you organize your business finances in a clear, easy-to-use way. Having the option to read the dates in a way that makes sense to you is very important. Many people prefer the format MM/DD/YYYY, which is most commonly used in Canada. I'll help explain how you can change your date format in QuickBooks Online. 

Here's what you'll do: 

1. Click the Gear icon. 

2. Select Account and Settings. 

3. Click Advanced. 
4. Scroll down to the Other preferences section and click the small Pencil icon. 

5. Change the date format. 

6. Click Done. 

Simple as that! I hope this gets you back to business. 

Cheers!
