The reference date of the Date Type data is 1900/01/01.
However, there are times when the data entered by mistake is data before the reference date.
I think that it is unnecessary for Date Type data because the data before the reference date is not subject to processing.
Therefore, when reading data with Data type node etc., if there is data before the reference date, please display a message notifying that.
