I don't know about that one, but there's at least one which tries to line up stardates with different Gregorian date references in the canon, rather than adhering to the "XX000.0 is New Year's Day" rule which tends to result in the crews of the Enterprise and Voyager facing down Borg when they should be getting drunk.I don't know how it works, but there are several sites like this one that can calculate a stardate for you. The odd thing is, when I've used that on Stardates from the books, they always end up off by couple months. I think it was that one, I've used a couple different sites in the past.
