Calculate Time To Respond from Dates

B

I am creating a spreadsheet that records:

Date Correspondence Received
Date Correspondence Answered

I want to add a new column that totals the days taken to do this.
Fairly simple on the face of it! However, I don't want to include
weekends in this total. Ideally, I'd like to be able to exclude public
holidays too - perhaps by having a list where I enter such dates and
they are then excluded from the calculation, but this may be a step too
far for my meagre skills...

Any ideas?

Regards,

Baldy

Try Networkdays

NETWORKDAYS(start_date,end_date,holidays)

Important Dates should be entered by using the DATE function, or a
results of other formulas or functions. For example, us
DATE(2008,5,23) for the 23rd day of May, 2008. Problems can occur i
dates are entered as text.

Start_date is a date that represents the start date.

End_date is a date that represents the end date.

Holidays is an optional range of one or more dates to exclude fro
the working calendar, such as state and federal holidays and floatin
holidays. The list can be either a range of cells that contains th
dates or an array constant of the serial numbers that represent th
dates.

Remarks

Microsoft Excel stores dates as sequential serial numbers so they ca
be used in calculations. By default, January 1, 1900 is serial numbe
1, and January 1, 2008 is serial number 39448 because it is 39,448 day
after January 1, 1900. Microsoft Excel for the Macintosh uses
different date system as its default.
If any argument is not a valid date, NETWORKDAYS returns the #VALUE
error value
