I am building a template to auto populate budget value by straight line based on task start/end date criteria. some tasks could give me correct duration distribution, but some don't. I am looking for If function, which could give me correct monthly allocation budget. Here is an example of what I am trying to achieve. task 0110 duration is from 09/15/07 to 05/24/08, duration month is 8. budget $34,465supposed to be allocated to 8 month starting from Sept, 07. but my if logic return 9 month instead.
I have two columns with dates (and times) in that I am trying to define how many days, hrs and mins have elapsed i.e. A1 has 12/12/06 21:00, B1 has 17/12/06 21:00. C1 has B1-A1 and is custom formatted to show as dd"days" hh"hrs" mm"mins". In this case it will therefore show as 5days 0hrs 0mins. Which is correct.
However, if more than 1month has elapsed then the format m"m" d"days" h"hrs" m"mins" does not work. For example 17/03/06 03:00 to 20/12/06 07:00 shows as 10m 4days 4hrs 00min, which it clearly isn't.
I know the reason it does this is because it calculates the difference between the two times and adds that to it's 0 value, which in my format is 01/01/1900 00:00. therefore when it adds 277days (the answer) it becomes 04/10/1900 04:00, so my formatting is just calling the month value ('10') and the day value ('4').
I understand the reason it does this, 277 days on from 01/01/1900 is indeed Oct 4th, but 277 days on from 17/03/06 is not 10months and 4 days as there are different length months in between. It also seems to add a month on, possibly because the format for 'months' is between 1 & 12 and therefore cannot begin at 0?
Does anyone know if it's possible to force excel to work out the correct number of months and days have elapsed between two dates and not apply it to 01/01/1900? Or any other possible solution, maybe with a different custom format?
I want to display the percentage of occupancy for each month for condo rentals.
I have columns with dates that represent bookings throughout the year. check in and check out dates to be more precise. (A1 and B1 for example) and I have columns with months Jan, Feb, etc. (C1, D1, etc. for example)
The problem I run in to is that I can calculate the number of days between the dates and the fraction of the year (*12 to get a monthly value, but I fail to understand how I can break that up so that I can populate each month with a correct percentage of the total term.
E.g. A1=1-jan-2014 and B1=20-jan-2014 is an easy one because it only covers 1 month: formula: =(YEARFRAC(A1,B1,3))*12 gives me 62,47% which I could just use as is for that month.
So far so good, but when the period covers more than one month or when the months overlaps, I don't know how to break the outcome up into the appropriate months to display the correct percentage for each month in its own column.
e.g. A1=1-jan-2014 and B1=20-Mar-2014 gives me a result of 253% with the same formula. 100% for November, 100% for December and 63% for January, which I could somehow formulate to break up over different Months.
But then it gets more tricky. What if the booking starts on a day other than the 1st of the Month?
e.g. A1=5-jan-2014 and B1=20-Mar-2014 The result of the formula (243%) is correct, but isn't sufficient to put the correct percentages for each month in their respective column.
What formula(s) should I use to break down the percentages to match the correct fraction of each individual month?
I attached an example of what I have so far for your review : test.xlsx
I need to be able to calculate age in months, and round whatever remainder to the middle of the month (.5). I am calculating z-scores and percentiles for in a childhood obesity project. The DoB and Date of measurements must be converted to read anything from 142.0 to 142.9 as 142.5.
This value will be used to look up the the appropriate LMS (Box Cox, Median, and Standard Deviation) in another excel table. I have to be able to compute age in months so 142.5, 143.5, 144.5, 144.5 etc. It is just not rounding off to the nearest half month.
I was asked by a colleague how they could put a persons date of birth in one cell, todays date in another, and return their age in years and months. Accuracy to within a month. This is what I gave them.
=TRUNC((B1-A1)/365.25)&" Years "& ROUND(((B1-A1)/365.25-TRUNC((B1-A1)/365.25))*12,0)&" Months"
Date entered Name Date of Birth (DOB) Occurrences of Name + DOB this Month Occurrences of Name + DOB within last 3 Months Occurrences of Name + DOB within last 6 Months
I can manage the occurrences this month but haven't a clue how to calculate the 3 and 6 months ones. I have attached a sheet.
I'm trying to make a formula that will calculate the average of the previous 12months. The goal is to tie the formula to a reference cell that contains a date. Each time the date is changed by a user the calculation will be updated accordingly. Here is the CSE formula that I thought would work:
I've also attached a sample file to illustrate the problem. The 'range' portion ($C$5,(COUNT(C5:$C$53)-1)[/b]of the Offset function was setup simply to get the 12 months which preceeded the reference date.
Start date: 12/04/2004 End date: 12/04/2006 The formula should give the answer to 24 months
Example 2 Start date: 12/04/2004 End date: 13/04/2006 The formula should give the answer to 25 months
When I use function =(YEAR(A4)-YEAR(A3))*12+MONTH(A4)-MONTH(A3), it does not show 25 months for "Example 2" as it is still within the same month "April"
finding a formula to calculate the number of months between two dates. I've attached an Excel spreadsheet with sample data. Some are in the future, and some are in the past.
I was wondering if this can be done we have a monthly award program so if a date was entered for that drive on this month it would = no if blank =yes but needs to reset each month?
=IF(AND('Driver'!A51:A1000)="",IF('Driver'!A51:A1000>='Driver Bonus'!A3,"YES","NO")) This brings back a #value! error
=IF(AND('Driver'!A51<=A3,'Driver'!A51>=A3),"NO","YES") this works but only for that cell i need to also recognize cells A51:A1000
=IF(MAX(INDIRECT("'"&A8&"'!A51:A1000"))<A3+1,IF(MAX(INDIRECT("'"&A8&"'!A51:A1000"))<>A3,"YES","NO")) this also works but only for 1 day
The issue is i want years and months between two dates which are not in computer language. Date like 2008/12 and 2010/01. File is attached for you reference
I have a table with model numbers as column A, and Row 1 contains dates, each columns contains net sales, my question is there any simple way to group all dates into months and years, i have tried using a pivot and it doesnt work correctly Screenshot (1).png
I would like a formula (if it is possible) that will list which months occur between two dates;
i.e Start Date (Cell ref A2) = 01/01/2010 (in the dd/mm/yyy format) End Date (A3) = 02/05/2010
In cells D2:O2 I have the months Jan-Dec. In cells D3:O3 I would like a "Yes" to appear if the above month occurs between the dates in A2 & A3. In this example would like a "Yes" to appear in cells D3, E3, F3, G3 & H3 but not in the other 'Months' appropriate cells.
say C2= 22/02/2007. in cell C4 When I use this formula =TODAY()-C2 to get the difference between today and a past date the result the formula give is 07/05/1900 i would like to receive the difference in Months between the past date and today? I.E. HOW MANY MONTHS IN BETWEEN
I have a large sheet of daily river flows and precipitation amounts, over 40+ years.
I want to calculate the average flows in each month of each year (ie 11/1968, 12/1968, 1/1969 etc). Dates are in Col A, flows in Col D.
How to average a particular month over all years like so:
{=AVERAGE(IF(MONTH(A2:A15282)=1,D2:D15282))}
But I don't know how to average per month of each year, or how to make a formula that will allow me to quickly calculate the averages of 100s of months.
I wrote code that works just fine, however, I realized there were parts of the data I was using that had 0's in it for holiday.
Bottom line, this is code that calculated the weighted average of prices for 12 months (12 rows across) and Drows across. I'm trying to use the "do while is empty" approach but can't get the syntax to work. Here's the code
Code: For r = 1 To drows Totwavg = 0 Tothours = 0 priceavg = 0
I am using the following formula to calculate years months and days in Excell 2007 =DATEDIF(C7,D7,"y") & " yrs, " & DATEDIF(C7,D7,"ym") & " mths, " & DATEDIF(C7,D7,"md") & " days"
I have a problem again with one of Date Dif function " =DATEDIF(I5|J5|"m") " in attached file i have this function applied to calculate number of months in between two given dates but it seems this function is not working properly or i am missing some info in this to make it run properly. How to fix this function or give me a proper one which can solve my problem to calculate accurate months between these dates in attached file...
