Dil,
Few date Macros are available with 'Easytreive addons' (which ofcourse are paid ones  ).
If you are lucky enough  , those may be installed at your shop  . |

Other?
You can use the programming function of EZT to calculate the difference between two dates. A small table of the number of days in each month would be a good starting point. The complexity increases if you have large multi-year spans and you really want a high degree of accuracy as you need to account for leap years. |

If the date is Julian the calc may be a bit more simple.
you can use DATECONV to change format. |
