Does anyone have any suggestions on how to determine the value within lists?
For example,
[1]
There is a given date in cell A1, 06-Jun without concerning year, I would
like to determine the value within column C, it should return 6 in cell A2,
because 06-Jun is equal to or larger than 05-Jun and less than 21-Jun.
[2]
There is a given date in cell A1, 05-Jun without concerning year, I would
like to determine the value within column C, it should return 6 in cell A2,
because 05-Jun is equal to or larger than 05-Jun and less than 21-Jun.
[3]
There is a given date in cell A1, 07-Mar without concerning year, I would
like to determine the value within column C, it should return 24 in cell A2,
because 07-Mar is equal to or larger than 05-Mar and less than 21-Mar.

Does anyone have any suggestions on how to do it in Excel?
Thanks in advance for any suggestions
Eric
