#### date calculation issues

```I need a formula that will calculate future dates for me. If I were to insert
todays date,(as an example) 13-june-2005 into excel, I need it to calculate 6
weeks, 6 months, 1 year, 2 years, 3 years and 4 years ahead of the date
specified. On top of this, the future dates cannot land on a weekend or a
holiday.  I am aware of the WORKDAY function but don't know how to use it. My
excel experience with formula's is limited. Very basic steps is required.

So long as you are going to use the ATP, then the EDATE function is the
simplest way of adding months to your initial date.  It takes care of the
problem that can occur when adding six months and not having the resultant
month have enough days.  Or adding years to 29 Feb 2004.

To use the WORKDAY function so as to avoid falling on a weekend or holiday, you
need to have a range, which you may name Holidays, that contains a list of all
the Holiday dates.  You then subtract 1 from the calculated date, and add 1
workday to that result.  The result will be the first non-holiday, non-weekend
after your computed date.  (If you want the day before, then add 1 to the
calculated date and subtract 1 workday).

A2:	Initial Date
B2:	=workday(A2+42-1,1,Holidays)    	(6 weeks)
C2:	=workday(edate(A2,6)-1,1,Holidays)	(6 months)
D2:	=workday(edate(A2,12)-1,1,Holidays)	(1 year or 12 months)
E2:	=workday(edate(A2,24)-1,1,Holidays)	(2 years or 24 months)
F2:	=workday(edate(A2,36)-1,1,Holidays)	(3 years or 36 months)
G2:	=workday(edate(A2,48)-1,1,Holidays)	(4 years or 48 months)

This should get you started.  Let me know how it works out.

Calculate Years/Months Between Dates and then Average
We are using the formula =DATEDIF(A1,NOW(),"y") & "." & DATEDIF(A1,NOW(),"ym") to calculate the years and months from an employee hire date. Is there an easy way to average the years and months for a group of employees with the results of that formula? You could use: =AVERAGE(A1:A10*1) Array-entered, meaning press ctrl-shift-enter. But you could also just change your current formula to: =1*(DATEDIF(A1,NOW(),"y") & "." & DATEDIF(A1,NOW(),"ym")) Then just use: =AVERAGE(A1:A10) which is *not* array-entered. ...

Calculated Fields 04-18-07
We're helping someone with a relatively basic requirement for CRM, but they've thrown two awkward ones into the mix. The first of which is a desire to use some custom fields on an entity which are then automatically totalled. e.g. when they do a quote each item on the quote (free entry) has a custom field for the cost to the organisation of providing the service. On the main quote screen/report they need these to be totalled, in the same way that the built-in sell-price fields are. Is this possible without reaching for Visual Studio?

How to sort by name then date?
I would like to look through all the emails to a particular person. If I click on the "To" column I can see all the emails to a particular person (actually there is a problem with that which I will mention next) but they seem to be in random order. Is there a way to have them sorted by date? (i.e. by name first, then by date). Actually, sorting on the "To" column does not get all the emails sent to a given email address. Because Outlook uses the "display as" field. It will often give different "display as" names to the same email address. C...

Concatenate including a date so that the date appears as a date
When I try to join the contents of several cells, one of which is a date and time obtained from =now(), the date and time part appears as a number. How can I make it appear as a date and time? I have tried changing the cell formats - probably there is a combination that works but I haven't found it. I also tried copying the original date cell to another cell and changing the latter cell's format and concatenating using that latter cell, but still no success. Use the TEXT function. For example, =TEXT(NOW(),"mmmm d, yyyy") would give January 6, 2010 "dd...
