Function for counting days between 2 dates for specific year

Hi,

I know the workday function can count days between 2 dates. But is there a way to count days only in a specific year.

Example:
6/10/16 - 3/21/17 How can I use a function to count only the number of days in 2016.

Thank you for any help you can provide.

Best,

Eric

Hi Glenn thanks for the response.

That is useful if all the rows in my column have the 2nd date in 2017. But some end in 2016 like 6/10/16 - 9/15/16. The function above would inflate the days in 2016. That's what I'm trying to solve, so the 2nd date is relevant. I didn't originally explain that well. I'm trying to drag this function down for a lot of rows.

Thank you both that did it.
