The function makes the assumption of a consistant number of seconds in every year.  This is not a true assumption.  Running the function and asking for the date 400 years ago

x=returnhistoricaldate(400);

returns the date of 01Mar1616

The below statement returns the correct date

y=as date(date mdy(month(today()),day(today()),Year(today())-400));

Jim,

As a quick development, making the assumption for data stored within the last 20 years would be fine.

I wrote this without the need to go back 400 years.

You are technically correct but for the purposes of this proof of concept 100% accuracy was not needed.

The script could be modified to use your idea described above.

Many Thanks.
