Show upcoming occasions

First of all, thanks.
But, if you use "small" function, it will return the smallest value from all, and I need the smallest without the "out-of-date" values.
Secondly, I need the exercises' numbers to be changed automatically too.

See the attached file, I added a table for example. I assumed the table is correct for May 15th 2015.
