how to compare dates...
i am trying to make a excel search engine for my file index so that a user can find a file based on the date of letter

PROBLEM
I am not able to compare date entered by the user with my existing database.. as the dates take some wierd form of get converted to the five digit excel format if formatted as text or general.... i want to have a wildcard or partial search.. so if the user enter Jan he gets all files of Jan month irrespective of month.. or if he enters Jan 18 he should be able to get all files made in Jan 2018 irrespective of date..
