[antlr-interest] Resolving ambiguity with dates and division operations

The problem is that the parser needs to be able parse formulas that
could contain math operations and/or operations with dates. The dates
are specified in the format "mm/dd/yyyy" or "mm/dd/yy", e.g.
"04/15/2003".

How would one go about writing rules to be able to distinguish dates
from math expressions containing several division operations, i.e.
04/15/2003 should be April 15, 2003 and not 4 divided by 15 divided by
2003?

Thanks
