I need a UDF that, given a date, returns the date of the Monday of that week.
For example, if the input was a value between 6/20/2005 and 6/26/2005, the
function would return 6/20/2005. If the input was 6/27/2005 the UDF should
return 6/27/2005.

All I can think of is a massive VLOOKUP table. There has got to be a
cleaner way.

Thank you in advance
