What makes you think Stata can't handle dates prior to 1900? If you want to keep track of Charlemagne's coronation, you certainly can:
g date = mdy(var1, var2, var3)
clonevar disdate = date
format disdate %td
+------------------------------------------+
| var1 var2 var3 date disdate |
|------------------------------------------|
| 12 1 1900 -21580 01dec1900 |
| 6 12 1899 -22117 12jun1899 |
| 4 15 1898 -22540 15apr1898 |
| 3 20 1842 -43020 20mar1842 |
| 11 1 1789 -62151 01nov1789 |
| 7 4 1776 -67019 04jul1776 |
| 1 1 800 -423681 01jan0800 |
+------------------------------------------+
Stata may not be well suited for explorations in Roman history, as the first date that it can represent is 01jan0100 (see help date) but the Dark Ages are no problem.
