Summation Blaze has always used a four-digit year format. Whatever display format you use, you can always enter the year component using 2 or 4 digits.
Summation can display dates in a multitude of formats.
Depending on the display format used, you have quite a bit of latitude in the method in which you may enter dates. This is sometimes referred to as a pivot point. For instructions on how to specify a larger 21-Century default range, click here .
