Calculating days in a month
Hello,
Hope someone can help. A1 = Start date B1=End Date eg A1 = 1st Jan B1=4th April C1=Days in Jan D1=Days in Feb E1=Days in Mar etc until Dec. Therefore for the above example C1 would = 31days D1 = 28days E1 = 31days and F1 = 4 days. I have been playing around with IF and DATEDIF but I'm getting nowhere. Any help would be much appreciated. |
C1: =DAY(DATE(YEAR(A1),MONTH(A1)+1,0))

Hi Bob
Wow, thanks for the quick response. I was really after a formaula that would take into account partial months. Therefore if Start Date = 15 Jan, End Date= 4th Apr Jan=17 days, Feb=28days Mar= 31day and Apr=4 days, May=0, Jun=0 etc. This is for when campaigns ran in a year, and which months it ran in. Andy.

Are you looking for a more variable formula, or will the start and end dates
always span 4 months? -- HTH RP (remove nothere from the email address if mailing direct) "STFC" wrote in message ... Hi Bob Wow, thanks for the quick response.

Sorry I haven't been that clear have I.
Yes a more variable formula - the campaigns can run for anything from a week to a year.

Okay, another shot.
Assuming that the start date is in A1, end date is in B1, and the campaign days are in C1:C12 In C1: =DATE(YEAR(A$1),MONTH(A$1)+1,1)-A1 Select all C2:C11 cells together, then enter this array formula into the formula bar (commit with Ctrlo-Shift-Enter) =IF(ROW(INDIRECT("2:100"))=MONTH($B$1),DAY($B$1),D AY(DATE(YEAR(A$1),MONTH(A$ 1)+ROW(INDIRECT("2:100")),0))*(MONTH($B$1)=ROW(IN DIRECT("2:100")))) -- HTH RP (remove nothere from the email address if mailing direct) "STFC" wrote in message ...

You can actually do it all inj one formula,
Select C1:C12, and enter this formula, again as an array formula =IF(ROW(INDIRECT("1:100"))=MONTH($A$1),DATE(YEAR(A $1),MONTH(A$1)+1,1)-A1,IF( ROW(INDIRECT("1:100"))=MONTH($B$1),DAY($B$1),DAY(D ATE(YEAR(A$1),MONTH(A$1)+R OW(INDIRECT("1:100")),0))*(MONTH($B$1)=ROW(INDIRE CT("1:100"))))) -- HTH RP (remove nothere from the email address if mailing direct) "Bob Phillips" wrote in message ...

Actually, this can be clarified as you are only running for up to one year
:-), and there is a problem with the formula. It works okay if the campaign starts in Jan, but any other month fails.

Hi Bob,
This is v impressive. I have some learning to do. This is close to working, but if the start date = 2nd Feb then Jan should have 0 days. As start dates and end dates could be any dates in the year. Also a campaign could just run in 1 month eg 8th Jan - 15th Jan which =8 days. Also is it possible to do the array where C1:N1 return the results. I feel I'm being a bit cheeky now, but thanks for all the help.

Can't resist another go, as it is still not right
=IF(ROW(INDIRECT(MONTH($A$1)&":"&MONTH($A$1)+11))= MONTH($A$1),DATE(YEAR(A$1) ,MONTH(A$1)+1,1)-A1,IF(ROW(INDIRECT(MONTH($A$1)&":"&MONTH($A$1)+11) )=MONTH($ B$1)+(YEAR($B$1)-YEAR($A$1))*12,DAY($B$1),DAY(DATE(YEAR(A$1),MONTH( A$1)+ROW( INDIRECT("1:12")),0))*(MONTH($B$1)+(YEAR($B$1)-YEAR($A$1))*12=ROW(INDIRECT( MONTH($A$1)&":"&MONTH($A$1)+11))))) This works in all cases I can see except where the campaign starts and ends in the same month. Getting a bit messy though. -- HTH RP (remove nothere from the email address if mailing direct) "Bob Phillips" wrote in message ...

I have done it so that C1 contains the month the campaign starts in, so Jan
is in C12 (that is next year). I spotted the same month problem in my last post, but it can be fixed, as long as the campaign doesn't go over a year). To use C1:N1, use this formula =IF((MONTH($A$1)=MONTH($B$1))*(MONTH($A$1)=COLUMN( INDIRECT(MONTH($A$1)&":"&M ONTH($A$1)+11))),$B$1-$A$1,IF(COLUMN(INDIRECT(MONTH($A$1)&":"&MONTH($A$1 )+11 ))=MONTH($A$1),DATE(YEAR(A$1),MONTH(A$1)+1,1)-A1,IF(COLUMN(INDIRECT(MONTH($A $1)&":"&MONTH($A$1)+11))=MONTH($B$1)+(YEAR($B$1)-YEAR($A$1))*12,DAY($B$1),DA Y(DATE(YEAR(A$1),MONTH($A$1)+COLUMN(INDIRECT("1:12 ")),0))*(MONTH($B$1)+(YEAR ($B$1)-YEAR($A$1))*12=COLUMN(INDIRECT(MONTH($A$1)&":"&MO NTH($A$1)+11)))))) -- HTH RP (remove nothere from the email address if mailing direct) "STFC" wrote in message ...

Hi Bob,
First time using this site, will definitely use it again. I'm quite glad I was right in thinking this wasn't easy to solve. The formula is v v impressive. The only problem is trying to get a campaign that starts in Mar to return 0 for Jan and Feb. Would it be easier to have 12 separate formulas for C1:N1 to induvidually workout if they had days running in that month? Thanks again for all your help, much appreciated.

Hi STFC (sorry, don't know your name)
As long as the start date and end date are in the same year, and start month will be less than end month, we can simplify the formula and get it the way you want =IF(AND(COLUMN(A1)MONTH($A$1),COLUMN(A1)<MONTH($B $1)),DAY(DATE(YEAR($A$1),C OLUMN(A1)+1,0)),IF(COLUMN(A1)=MONTH($A$1),DAY(DATE (YEAR($A$1),COLUMN(A1)+1,0 ))-DAY($A$1),IF(COLUMN(A1)=MONTH($B$1),DAY($B$1),0))) This is NOT an array formula, so just commit with Enter. -- HTH RP (remove nothere from the email address if mailing direct) "STFC" wrote in message ...

Here's another approach that will simplify the formulas. In C1:N1 put the
dates of the first of the months, i.e. Jan 1, 2005 through Dec 1, 2005. In C2:N2, put the last day of each month, i.e. Jan 31, 2005, Feb 28, 2005, ... Dec 31, 2005. (do that with a formula or literals). Then, with the start date in A3 and the end date in B3, put this formula in C3 =MAX(MIN($B3,C$2)-MAX($A3,C$1),-1)+1 and copy it across through N3 and down for as many rows as you need.

This is even closer now. The campign includes the day it satrts on. Using your formaula. Start date: 1st Jan End Date: 1st Feb returns 30days for Jan. For Feb: 24th 25th 26th 27th 28th = 5 days.

approaching it this way. Thanks. "Myrna Larson" wrote: Here's another approach that will simplify the formulas. In C1:N1 put the dates of the first of the months, i.e. Jan 1, 2005 through Dec 1, 2005. In C2:N2, put the last day of each month, i.e. Jan 31, 2005, Feb 28, 2005, ... Dec 31, 2005.

Hi Bob, This is v impressive. I have some learning to do. This is close to working, but if the start date = 2nd Feb then Jan should have 0 days. As start dates and end dates could be any dates in the year. Also a campaign could just run in 1 month eg 8th Jan - 15th Jan which =8 days. Also is it possible to do the array where C1:N1 return the results. I feel I'm being a bit cheeky now, but thanks for all the help.

Yes, I think this kind of formula is much easier to maintain. If you don't
like the "clutter", you can format C1:N1 as "mmm-yy" and hide row 2 (or vice-versa).

"Myrna Larson" wrote: Here's another approach that will simplify the formulas. In C1:N1 put the dates of the first of the months, i.e. Jan 1, 2005 through Dec 1, 2005. In C2:N2, put the last day of each month, i.e. Jan 31, 2005, Feb 28, 2005, ... Dec 31, 2005. (do that with a formula or literals). Then, with the start date in A3 and the end date in B3, put this formula in C3 =MAX(MIN($B3,C$2)-MAX($A3,C$1),-1)+1 and copy it across through N3 and down for as many rows as you need.

And eg 24th Feb to 10 Mar would return 4 days in Feb and not 5. This is making a lot more sense now though - thanks.

Hi Bob, First time using this site, will definitely use it again. I'm quite glad I was right in thinking this wasn't easy to solve. The formula is v v impressive. The only problem is trying to get a campaign that starts in Mar to return 0 for Jan and Feb. Would it be easier to have 12 separate formulas for C1:N1 to induvidually workout if they had days running in that month? Thanks again for all your help, much appreciated.
