Hi,

I have this sheet with almost all formulas of sumproduct. Calculations
based on start/end dates.
It takes quite some time calculating all the formulas.
Do expand the columns to see the sumproduct formulas.

Here I would like to have some macro to run after I mention dates and
calculate all the results.

Thx.
