Change the low date range regional setting.

[genesearcher]

In genealogy I need to list the 4-digit year. I'm trying to create a
spreadsheet that sorts on date. The low end of the date range in regional
settings is 1930. I need to push this back to make excel recognize the older
dates. How do I do it?

Enter a 4 digit year when you enter the data.

But excel doesn't see dates before January 1, 1900.

John Walkenbach has an addin you may want to get if you're dealing with dates
before 1900.
