Excel Formula

Experts - I am going mad and confused with the below formula.

Basically i have 6 dates in excel as columns. Each of these are some milestone dates. Date 1 cannot be blank. and if Date 2 is blank, subsequent dates also will be blank.

I need to find the sum of each dates & add it as total sum.

1. If date2 is blank, then display blank as result.
2. If date3 is blank, then display date2 - date1 as result
3. If date4 is blank, then display (date2-date1) + (date3-date2)
4. If date5 is blank, then display (date2-date1) + (date3-date2) + (date4-date3)
5. If date6 is blank, then display (date2-date1) + (date3-date2) + (date4-date3) + (date5-date4)
6. if no blank in any dates, then display (date2-date1) + (date3-date2) + (date4-date3) + (date5-date4) + (date6-date5).

Kindly help
