I am trying to calculate the average difference between two columns in excel. The columns contain a planned and an actual date, I would like to get the average difference but only for planned dates within the last three months.
Example:
Planned Start Date | Actual Start Date
21/09/2013 | 25/09/2013
10/07/2014 | 16/07/2014
01/06/2014 | 30/06/2014
The formula should only take line 2 & 3 (line 1 is older than 3 months), look at the difference in days for each applicable line (line 2: 6 days, line 3: 29 days) and then show the average ( 17.5 days) of all applicable lines.
Does anybody have a formula for this? Excel really isn't my strong suit...
Assume your data is in A2:B4 then try this array formula
=AVERAGE(IF(TODAY()-A2:A4<=90,B2:B4-A2:A4))
It assumes each month is 30 days (hence the 90)
Press CTRL + SHIFT + ENTER to enter the formula as an array formula
Based on your example I get a result of 17.5 days.

I have a question related to EXCEL:
Since I have the following prices for different period, how can I compute in an automatic way, for example the price between 10 June - 15 July ?
EDIT--> Expected output:
50€+50€ (10-11 june) + 58€x13 (period 12 june - 25 June) + 75€x13 (period 26 june - 9 July) + 92€x5 (period 10 july-15july) = 2289€
This is the same pictures with the cells in excel, please do not consider the "Price of period", but only the daily price
You could do this with a (lengthy) calculation:
Consider:
A8 Contains the from date (10-06-2021)
B8 Contains the from date (17-07-2021)
=(MIN($B$8,D3)-MAX($A$8,C3)+1)*C5+(MIN($B$8,F3)-MAX($A$8,E3)+1)*E5+(MIN($B$8,H3)-MAX($A$8,G3)+1)*G5+(MIN($B$8,J3)-MAX($A$8,I3)+1)*I5
This will consider a period from 10-06 - 11-06 a period of 2 days. And also 12-06 - 25-06 a period of 14 days, and so on.
The result is: 2514.00
One method would be to create a lookup table and use a formula.
Given your data, your lookup table might as shown below:
I NAME'd it: priceTable
You can then use the formula:
=SUM(VLOOKUP(SEQUENCE(End-Start+1,,Start,1),priceTable,2))
If, for some reason, you cannot easily create priceTable, you can create it with a formula (depending on your version of Excel):
=INDEX($C$4:$I$6,{1,3},{1;3;5;7})
Note: All of the formulas assume your dates are real dates and not strings.
If your version of Excel does not have the SEQUENCE function, you can replace it with:
=SUM(VLOOKUP(ROW(INDEX($A:$A,Start):INDEX($A:$A,End)),priceTable,2))

Date | Time | Table | Checkin Time | Bill Number ..| .. |
7/1/2018 **18:03:48** **6** **18:03:48** **4332**
7/1/2018 18:11:23 **6** **18:03:48** **4332**
7/1/2018 18:23:10 **6** **18:03:48** **4332**
7/1/2018 19:24:11 8 19:24:11 4333
7/1/2018 19:56:17 8 19:24:11 4333
7/1/2018 20:31:11 *6 20:31:11 4332*
I need to calculate Checkin Time which is 1st time of table number and bill number.
For example See one customer checkin at 18:03:48 with table number 6
His Bill number is 4332 .
So for table number 6 and Bill number 4332 chekin time will be 1st time
which is 18:03:48.
So I applied the formula:
=IF(AND(E3=E2,C3=C2,A3=A2),D2,MIN(OFFSET(E3,0,-3,MATCH(0,(E3:E$35470=E3)*(C3:C$35470=C3)*(A3:A$35470=A3),0)-1,1)))
But the value changes at 6th row .
It's giving 20:31:11 as checkin time .
It should be 18:03:48 because the 6th row table number and bill number is same as 1st one.
So How do I make it possible, to calculate the checkin time as per 1st time who have same bill and table number , no matter which row .
Here is the excel file I have uploaded to Google drive.
Here is the screenshot.
Edit:- Formula by #jeeped work, But as the log is of 30 days
The data keeps repeating the other day too.
Can it be done by giving some unique date value ?
If you don't have the newer MINIFS and MAXIFS, use AGGREGATE to achieve the same result.
=AGGREGATE(15, 7, ((A$2:A$7)+(B$2:B$7))/((C$2:C$7=C2)*(E$2:E$7=E2)), 1)
Format the result any way you want; as date and time, time only, etc.
You can make use of an array formula combining INDEX+MATCH to return the earliest time value that matches your conditions first. In cell D2, enter the following:
=INDEX($B$2:$B$7,MATCH(1,($C$2:$C$7=C2)*($E$2:$E$7=E2),0))
When returning, be sure to press CONTROL+SHIFT+ENTER instead of just ENTER to make sure the formula calculates correctly.
#Jeeped's answer is spot on, here is an adjustment for the formula to work over multiple days that have the same table numbers and bill numbers:
=AGGREGATE(15, 7, ((A$2:A$13)+(B$2:B$13))/((C$2:C$13=C2)*(E$2:E$13=E2)*(A$2:A$13=A2)), 1)
All I did was add this extra conditional argument, that checks if the "Date" is the same:
*(A$2:A$13=A2)
I need to make week number based on given date.
Today 28-08-18
Week .....
30-07-18 1
06-08-18 2
13-08-18 3
20-08-18 4
27-08-18 5
03-09-18 6
10-09-18 7
17-09-18 8
24-09-18 9
01-10-18 10
08-10-18 11
15-10-18 12
22-10-18 13
29-10-18 14
I want the cell next to "week" to be based on today's date.
Assuming 30-07-18 is located # A1. in B1, type in :
=WEEKNUM(A1,2)-WEEKNUM($A$1,2)+1
and drag it down. Glad that you'd tried. ( :
All the best.
Start by inserting a date in any cell, that will be the first week.
Create a function that calculates the difference between its adjacent
cell and the first and divides it by 7. Voilà you've got the week number. You can round it if you want.
The formula is as follows: Floor((First date - Current date)/7).

Good luck,
Alex
Your base date (BD) may not be the start of the week (SOW), so the general solution could be
calculate the SOW from your base date: SOW = BD - WEEKDAY(BD)+2
calculate the distance DI from given date (GD) to SOW: DI = GD - SOW
convert distance into weeknumber W = INT(DI/7)
EDIT:
SOW = IF(WEEKDAY(BD)=1;BD-6;BD-WEEKDAY(BD)+2)
this is to cover cases where BD is a Sunday and SOW should be the Monday before (not after)
I’m trying to compare a measure as of today through the same day and month for the prior 4 years (e.g. through June 6 of 2016, 2015, 2014, etc.).
For each year, I decided to count the number of days since the beginning of the year, and sum my values through that number of days for each year.
To identify whether a date should be included in the year to date comparison, I used the formula where my date is in cell A1:
=IF((A1-DATE(YEAR(A1),1,1)+1)<=(TODAY()-DATE(YEAR(TODAY()),1,1)+1),1,0)
I’m looking for a way around the issue of the extra day added to leap years. In other words, after February 28th, the day count will always be off by one in a leap year, and trying to use Februrary 29th in a non-leap year will return an error.
I’d like to adjust this formula, but I’m open to using a different function & formula if it gets me the right results.
you can check any information about February, 29th. If an error occurs, you know its no leap year. Catch that error with =IFERROR(;).
Assuming a table structure like this:
A:Date | B:Value
----------------------
01/01/2016 | 0
01/01/2015 | 1
01/01/2014 | 2
01/01/2013 | 3
01/01/2012 | 4
Formula
To - for example - calculate the average of the previous four (excluding the current) years on January 1st (today is 01/01/2016):
=SUMPRODUCT(
(MONTH(A:A)=MONTH(compare))*
(DAY(A:A)=DAY(compare))*
(YEAR(A:A)>YEAR(compare)-5)*
(YEAR(A:A)<YEAR(compare))*
(B:B)
) / (
SUMPRODUCT(
(MONTH(A:A)=MONTH(compare))*
(DAY(A:A)=DAY(compare))*
(YEAR(A:A)>YEAR(compare)-5)*
(YEAR(A:A)<YEAR(compare))*
1
)
)
Result
For the above example, the result is 2.5
Explanation
To select only those rows representing the same month and day:
(MONTH(A:A)=MONTH(compare))*(DAY(A:A)=DAY(compare))
To select only those values from the previous 4 years (excluding the current):
(YEAR(A:A)>YEAR(compare)-5)*(YEAR(A:A)<YEAR(compare))*
The actual values we are interested in:
(B:B)
Divide by 4 for the average over the last four years. This assumes there is no missing data which might be an issue. You could use another SUMPRODUCT (replace B:B with 1) to count the number of resulting rows and divide by that number to handles this case. This seems to be rather slow, but it works.
Note
For performance reason you should not use A:A (a full column) in the formula, just use the actual range you need, which will likely be much faster.
I have xls file in following format
Name 1 2 3 4
John 09:00-21:00 09:00-21:00
Amy 21:00-09:00 09:00-21:00
Where 1,2,3,4 and so on represent days of current month,
09:00-21:00 - working hours.
I want to calculate salary based on the following conditions:
09:00-21:00 - 10$/hour
21:00-00:00 - 15$/hour
00:00-03:00 - 20$/hour
etc.
and so on (every hour can have it's own cost, for example 03:00-04:00 - 20$/hour, 04:00-05:00 - 19$/hour, etc.)
How can i accomplish this using only Excel (functions or VBA)?
P.S. Easy way: export to csv and process in python/php/etc.
Here is a non-VBA solution. It's a pretty nasty formula, but it works. I am sure it could be made even easier to use and understand with some more ingenuity:
Assuming the spreadsheet is set up like this:
Enter this formula in cell G1 and drag down for your data set:
=IF(ISBLANK(B2),"",IF(LEFT(B2,2)<MID(B2,FIND("-",B2)+1,2),SUMIFS($P$2:$P$24,$Q$2:$Q$24,">="&LEFT(B2,2),$Q$2:$Q$24,"<="&MID(B2,FIND("-",B2)+1,2)),SUMIF($Q$2:$Q$24,"<="&MID(B2,FIND("-",B2)+1,2),$P$2:$P$24)+SUMIF($Q$2:$Q$24,">="&LEFT(B2,2),$P$2:$P$24)))
To explain the formula in detail:
IF(ISBLANK(B2),"" will return a empty string if there is no time for a given person / day combination.
LEFT(B2,2) extracts the start-time into an hour.
Mid(B2,Find("-",B2)+1,2) extracts the end-time into an hour.
IF(LEFT(B2,2)<MID(B2,FIND("-",B2)+1,2) will check if the start-time is less than the end-time (meaning no over-night work). If the start-time is less than the end-time, it will use this formula to calculate the total cost per hour: SUMIFS($P$2:$P$24,$Q$2:$Q$24,">="&LEFT(B3,2),$Q$2:$Q$24,"<="&MID(B3,FIND("-",B3)+1,2))
If the start-time is higher than the end-time (meaning overnight work), it will use this formula to calculate: SUMIF($Q$2:$Q$24,"<="&MID(B3,FIND("-",B3)+1,2),$P$2:$P$24)+SUMIF($Q$2:$Q$24,">="&LEFT(B3,2),$P$2:$P$24)
The use of the Find("-",[cell]) splits the start-and- end times into values excel can use to do math against the Time / Cost table.
The formula in column Q of the Time / Cost table is =VALUE(MID(O2,FIND("-",O2)+1,2)) and turns the ending hour to consider the cost into a value Excel can use to add, instead of having the text from your original source format.
Do this in VBA! It is native to excel and is easy to learn. Functionally, I would loop through the table, write a function to calculate the dollars earned based on the info given. If you want your results to be live updating (like a formula in excel) you can write a user defined function. A helpful function might be an HoursIntersect function, as below:
Public Function HoursIntersect(Period1Start As Date, Period1End As Date, _
Period2Start As Date, Period2End As Date) _
As Double
Dim result As Double
' Check if the ends are greater than the starts. If they are, assume we are rolling over to
' a new day
If Period1End < Period1Start Then Period1End = Period1End + 1
If Period2End < Period2Start Then Period2End = Period2End + 1
With WorksheetFunction
result = .Min(Period1End, Period2End) - .Max(Period1Start, Period2Start)
HoursIntersect = .Max(result, 0) * 24
End With
End Function
Then you can determine the start and end time by splitting the value on the "-" character. Then multiply each payment schedule by the hours worked within that time:
DollarsEarned = DollarsEarned + 20 * HoursIntersect(StartTime, EndTime, #00:00:00#, #03:00:00#)
DollarsEarned = DollarsEarned + 10 * HoursIntersect(StartTime, EndTime, #09:00:00#, #21:00:00#)
DollarsEarned = DollarsEarned + 15 * HoursIntersect(StartTime, EndTime, #21:00:00#, #00:00:00#)
I have a method that uses nothing but formulas. First create a lookup table which contains every hour and rate in say columns K & L, something like this:
K L
08:00 15
09:00 10
10:00 10
11:00 10
12:00 10
13:00 10
14:00 10
15:00 10
16:00 10
17:00 10
18:00 10
19:00 10
20:00 10
21:00 15
22:00 15
23:00 15
Make sure you enter the hours as text by entering a single quote before the digits.
Then if your hours were in cell B2 you could then use this formula to calculate the total:
=SUM(INDIRECT("L"&MATCH(LEFT(B2,5),K2:K40,0)&":L"&MATCH(RIGHT(B2,5),K2:K40,0)))
All the formula is doing is getting the left and right text of your work time, using MATCH to find their positions in the lookup table which is used to create a range address which is then passed to SUM via the INDIRECT function.
If you need to worry about minutes all you need to do is create a bigger lookup table which holds every minute of the day. You may need to add some extra logic if your work days span midnight.
