Unfortunately you just have to try each format it might be. If you give an example format, strptime will attempt to parse it for you as discussed here.

The code will end up looking like:

import datetime    

POSSIBLE_DATE_FORMATS = ['%m/%d/%Y', '%Y/%m/%d', etc...] # all the formats the date might be in

for date_format in POSSIBLE_DATE_FORMATS :
    try:
        parsed_date = datetime.strptime(raw_string_date, date_format) # try to get the date
        break # if correct format, don't test any other formats
    except ValueError:
        pass # if incorrect format, keep trying other formats
