Difference between DateValue and CDate in VBA

Question

I am new to VBA and I am working on a module to read in data from a spreadsheet and calculate values based on dates from the spreadsheet. I read in the variables as a String

Answer 1

CDate will convert a number or text to a date.

CDate(41035) 'Converts to a date of 5/6/2012
CDate("1/15/2014") 'Converts to a date of 1/15/2014

DateValue will convert date in text format (only) to a date.

DateValue("1/15/2014") 'Converts to a date of 1/15/2014
DateValue(41035) 'Throws a mismatch error
