Formula to search, match value, search again, return SUM

Looking for a formula to do the following.

1. Search a range of cells, say A25 through Z25, for the word Monday. It will appear several times. Let's say Monday is in C3 and D4.
2. Each time Monday is found, OFFSET for the 6 rows directly below the word Monday.
3. Return the SUM the numbers in the OFFSET cells.

Thanks everyone!
