Excel Date Formula + 3 Months - excel

I am looking to have a formula that takes the date that is manually input in a cell (E2) and automatically populates a date in the column next to it (F2) that is + 3 months from the date manually input in (E2).
eg. If (E2) has 03/11/2021 input manually then the formula in (F2) would populate 03/02/2021. image of part of the sheet

Is this what you are looking for?
=DATE(YEAR(A1),MONTH(A1)+X,DAY(A1))
where X = 3

One can use EDATE():
=EDATE(A1,3)
The second criteria is the number of Months to add.
EDATE will go to the number of months then try to equate the day. If the day exceeds the number of days in the target month it returns the last day of the target month.
For example =EDATE(DATE(2021,11,30),3) will return the 28th of February 2021.

What function do I need for getting year-to-date % increase over prior year?

I have an excel workbook for multiple restaurants that has sheets for every year labeled with their sales per month. I am attaching an example of one row of the sheet for the year 2020. I would like to have a cell at the end of each row that shows the % increase or decrease over the prior year up to the last month entered. It would be pulling the information for the results from the prior sheet. I don't know which function to use or how to get the function to only add the corresponding months to date from last year. For example, on the sheet for 2020, sales are listed through July but the sheet for 2019 has all 12 months listed. I would like to include a cell that gives me the year-to-date % through whatever current month it is.
Sheet for Year 2020
If you want to use only the columns filled in the current year in the percentage calculation, you can use following formula:
=SUM(B3:M3)/SUMPRODUCT(B2:M2*(B3:M3>0))-1
First count how many cells are blank in your current year using the
=COUNTBLANK()
Then sum up the year you are comparing to starting at january then going 12 - result of blankcells formula to the right.
=SUM(OFFSET(JANUARY_CELL_REF, 0, 0, 1, 12-COUNTBLANK(this_year)))
Then you just divide it by the results this year so far:
=result_So_far_this_year / SUM(OFFSET(JANUARY_CELL_REF, 0, 0, 1, 12-COUNTBLANK(this_year)))
Finally format is as a percent.

How to collect number of days from a month in excel

I have a column which will have some days from a month in dd-mm-yyyy format. What I need to get total number of days from each month mentioned in that column. The column might not contain all days from each month.
Example :
Column A :
2017-01-01
2017-01-02
2017-01-17
2017-01-27
2017-02-08
In above example, from 2017 Jan, I have 4 days and from Feb I have one day. I need this count for a IF statement to run in C column. ie, in C1 there will be an IF function which will check the month in A1 and count the total number of days for that specific month from A column. If that count is below a specific digit, I need to perform a formula otherwise a different one. This will repeat for all C cell
If this column contains all date from each month I can use Day function to get total days, but here how Can I collect it
This will work: =SUMPRODUCT(1*(MONTH($A1:$A5)=D1))
And an example of manipulating basing on the result:
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=D1))<3;"good";"bad")
Another one when row number represents a month (JAN in C1, FEB in C2...):
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=ROW()))<3;"good";"bad")
In your case:
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=ROW()))<10;function1();function2())
Array formula - use Ctrl+Shift+Enter:
=SUM((MONTH($A$1:$A$5)=MONTH(A1))*(YEAR($A$1:$A$5)=YEAR(A1)))

How to calculate the number of weeks between 2 date range in excel

I have a question here, I have 3 columns in excel, A1 is being the calendar date; column B1 has the fiscal_quarter_start_date ; and fiscal_quarter_end_date in column C1.
I am trying to find the number of week falling in between the A2 and A3. The issue here is I should consider the first sunday as the first week of the quarter. My fiscal year starts on Feb of every month.
The reason I am doing this calculation is to populate the count of weeks numbers of a quarter, where my first week starts from the first sunday of the quarter.
=ROUNDUP(MOD(IF(A13>=IF(DATE(YEAR($A13),2,1)=1,DATE(YEAR($A13),2,1),DATE(YEAR(A13),2,7-WEEKDAY(DATE(YEAR(A13),2,1),1)+2)),ROUNDUP((A13-IF(WEEKDAY(DATE(YEAR(A13),2,1),1)=1,DATE(YEAR($A13),2,1),DATE(YEAR($A13),2,7-WEEKDAY(DATE(YEAR($A13),2,1),1)+2))+1)/7,0),ROUNDUP((A13-IF(DATE(YEAR($A13)-1,2,1)=1,DATE(YEAR($A13)-1,2,1),DATE(YEAR($A13)-1,2,7-WEEKDAY(DATE(YEAR($A13)-1,2,1),1)+2))+1)/7,0)),13.01),0)
above is the formula i've got all the way. However rounding up with 13 is not a viable solution as its not necessary that it should have always have 13 weeks all the time.
For example: 5/1/16 should be week 1 As it is a begging of a q2 and 5/1/16 is the starting on Sunday. In this case using above formula result for the week is 13
Please help me..
You can use WEEKNUM to get the week number.
However you mentioned that your week wont end at the Saturday, but at the Sunday, so you have to do =WEEKNUM(<insert here where the date is>,2)
=WEEKNUM (serial_num, [return_type])
serial_num - A valid Excel date in serial number format.
return_type - [optional] The day the week begins. Default is 1.
Return_type can either be 1 or 2:
1 - Week begins on Sunday
2 - Week begins on Monday
or... read it here for counting weeks between 2 dates.
Enter this formula =(A2-A1)/7 into a blank cell, (A2 indicates the end date and A1 is the start date)
If you just want to get the whole weeks, please apply this INT function: =INT((A2-A1)/7)
Try it here, on sheet "week"
Hope it'll help.
Assuming that the Quarter start and end dates are in A3:A6 respectively then:
=IF(AND(C1>=$A3,C1<$A4),WEEKNUM(C1)-WEEKNUM($A3)+1,IF(AND(C1>=$A4,C1<$A5),WEEKNUM(C1)-WEEKNUM($A4)+1,IF(AND(C1>=$A5,C1<$A6),WEEKNUM(C1)-WEEKNUM($A5)+1,WEEKNUM(C1)-WEEKNUM($A6)+(IF(AND(C1>=DATE(YEAR(C1),1,1),C1<DATE(YEAR(C1),MONTH($A6),DAY($A6))),53,1)))))
This is checking whether the date in the cell above (C1) is between the quarter start and end dates, and checking the difference in weeks from the start date. To cover the anomoly for Q4 extending into the next year, the IF statement at the end adds 53 instead of 1 for the affected dates.
Edit #1
=WEEKNUM(A1)-WEEKNUM(B1)+IF(AND(A1>=DATE(YEAR(A1),1,1),A1<DATE(YEAR(A1),MONTH(B1),DAY(B1))),53,1)
This works for the A1:C1 format you mentioned in your comment. Obviously this relies on B1 and C1 being updated manually.
Edit #2
=WEEKNUM(C1)-WEEKNUM(B1)
If you are counting 05/01/2016 as week 1 then add 1 to the result. Take off the highest week number (default is counting from sunday or you can change to (C1,1) if you want to define it exactly) from the lowest week number. Reult is 13 which would match the manual calculation.
You will want to look at the previous edit for an example of the if formula you will need when the quarter ends in another year. to reverse the negative figure it will need to add 52 when the date is in the early part of the next year and 0 when it is not.
You can use the "hidden" function DATEDIF:
For example in A1 we write start date (01/05/2016), in B1 - end date (31/07/2016) and in C1 = DATEDIF(A1,B1,"d")/7 the result will be 13

Excel - how to get if a date is a specific day of the week?

I have a spreadsheet that tracks average file processing times over the course of a month. One of the macros and stats that we like to pull, is performance on Mondays (as the files are a little built up over the weekend). The spreadsheet is organized into columns by weekdays of the month:
The dates are formatted MM/DD/YYYY, so I would think Excel has a date function that it can determine weekday based on that date value.
Currently, I just have to manually tell the Macro which columns are Mondays, like so:
=AVERAGE(B20,G20,L20,Q20)
So, instead of manually, how would I get the average over the range of say, B20 to V20, only if the day of the week is Monday (the date cells are in row 1, so B1 to V1)?
To determine the weekday of a date in EXCEL use the =WEEKDAY() formula, which evaluates as 1 (Sunday) to 7 (Saturday)
e.g. If A1 contains 12/31/2016 (or 31/12/2016 if you're from where I'm from), the formual =WEEKDAY(A1) would evaluate to 7 (indicating that the last day of 2016 was a Saturday)
To apply this formula to your problem: (assuming that the dates are in row 1 and the values are in row 2)
insert a new row to hold the WEEKDAY() value (say, row 2)
in cell A2 type in =WEEKDAY(A1)
copy this formula as far right as necessary (to include all your dates)
Your average for Mondays is calculated as =AVERAGEIF(2:2, 2, 3:3)
Possibly, you can add a column called [Day Of The Week] and use the following formula to display the day.
TEXT(B4,"dddd")
Then add an 'If'statement to your result cell.
simply
=SUMPRODUCT((MOD(B1:V1,7)=2)*B20:V20)/SUMPRODUCT((MOD(B1:V1,7)=2)*1)
should give the average of all values from B20 to V20 if the corresponding cell in row 1 is a monday.
the first part sums the values of all mondays and the second part counts them (sum / count = average) ;)
If you have any questions, just ask.
If your date is in A1, you can use =Text(A1,"dddd") to determine the day of the week (it will return the name, "Monday", "Tuesday", etc.) so then you could do perhaps:
=If(text(A1,"dddd")="Monday",[do whatever],[do whatever]) (may need a helper row/column to hold the text of the weekday)
(Or use AverageIf() and use the Text() idea.)

Find last digits with IF

I have lots of cells in the spreadsheet that contains the whole year, date and stock prices, but I only need the dates from 25th of the last month till the 5th of this month.How can I write a function to do that? For example if the cells are like this in the column:
19900101
19900102
19900103
19900104
19900105
.
.
19900125
19900126
19900127
19900128
19900129
19900130
19900131
I want it to show only days (1,2,3,4,5,25,26,27,28,29,30,31) with the date format.
The date shows in the text format and I've tried format cell to change it but it doesn't work.
For a slightly different approach, assuming you want to return the A2 value only if it represents a date in the last 5 or first 5 days of any month you can use this formula in B2
=IF(DAY(TEXT(A2,"0000-00-00")+5)<11,A2,"")
TEXT function converts your data to a real date then if you add 5 days to that date then any date that was originally in the last 5 or first 5 of the month will now be in the first 10 days of the month.....so it's sufficient to check that the day is < 11. That will pick up 27th to 31st of a 31 day month, 26th to 30th of a 30 day month etc.
you could use a formula and then filter by rows with data...
As an example (given it's difficult to discern if you always want the first 5 and last 5 of a month or what....)
=IF(RIGHT(A2,2)*1<=2,A2,IF(RIGHT(A2,2)*1>=29,A2,""))
Based on all the edits and comments, these should be the function you need.
=IF(OR(A7-A2>5,MOD(A2,100)<=5),DATE(LEFT(A2,4),MID(A2,5,2),RIGHT(A2,2)),"")
You should place it in cell B2 and then do all the desired filtering, as explained in xQbert's answer.
