Excel overriding date format

[DaveH440]

For years I've been entering dates on a spreadsheet in the format yyyy/mm/dd. Now Excel has gotten "smart" and reverses them to dd/mm/yyyy.  I can now only correct new entries by laboriously customizing each entry. There must be some way to universally reset the format to my original form. But how?

Change the way your dates are displayed in Windows date and time settings. Excel uses that to decide how to display them.

Thanks for your response, But MS doesn't seem to offer the date option "yyyy/mm'dd"/ Meanwhile, I have solved my problem by switching the format of my date column to "text". Then I can enter dates in any format I want.
Thanks again,
