I have some calculations that are strongly dependent on "this week", "next week", etc.
Let's say I have a date (Column A). I can use WEEKNUM((A1), 2) in Column B to get the week number.
In Column C, I can enter this formula to check if the event is this week or next week.
=IF(B1=WEEKNUM((TODAY()),2),"this week",IF(B1=WEEKNUM((TODAY()+7),2),"next week","way in the future"))
This all works great until I have events that cross into next year. So December 31, 2019, will be week 53 and December 31, 2020, will be week 53.
This is an issue because I need a way to account that December 31, 2020 happens later than December 31, 2019.
How do I account for change in years in this formula?
Update:
Adding YEAR as an additional condition will allow me to compare if the date HAS a different year but it still won't let me dynamically calculate, this week, next week.
In this second example, I set two dates and set my computer time as December 31 2019. The result is that instead of reporting 1/1/2020 as "next week" the formula returns "way in the future" which is incorrect.
Is there basically a way to subtract or add weeks using serial week number since epoch time?
Eh, I think I figured it out. Instead of comparing week numbers, we extract the Monday of each week and perform a similar comparison like before. Except we now have the entire date instead of just the week number.
=IF(A2-MOD(A2-2,7)=TODAY()-MOD(TODAY()-2,7),"this week",IF(A2-MOD(A2-2,7)=TODAY()-MOD(TODAY()-2,7)+7,"next week","way in the future"))

Working on a formula that will take a date and translate it to the format FYxxPxxWx.
For example. Input the date of 03/22/20 and the formula will give you FY20P06W4 which is correct.
However if you input 02/02/20 the formula will give you FY20P05W2. The correct output would be FY20P05W1. This issue also rears its head with the date 09/29/19. It gives you FY20P12W5. The correct output would be FY20P1W1.
Something else weird happens when you put in the date 04/5/20 you get FY21P07W2 when it should be FY20P07W2.
The formula is
=CONCATENATE("FY",RIGHT(YEAR(DATE(YEAR(D5),MONTH(D5)+(10-1),1)),2),"P",TEXT(CHOOSE(MONTH(D5),4,5,6,7,8,9,10,11,12,1,2,3),"0#"),"W",WEEKNUM(D5,1)-WEEKNUM(DATE(YEAR(D5),MONTH(D5),1),1)+1)
I think this issue is caused by the strange weeks where the the month ends and another begins throwing off the formula.
I do have a formula that calculates the years fiscal year start date
=(DATE(YEAR(TODAY())-1,10,1)-(WEEKDAY(DATE(YEAR(TODAY())-1,10,1),1)))+1
This outputs 09/29/19 as the start date of the Fiscal year as its the same week as 10/1/19 which is the first month of the fiscal year. IF that makes sense.
The separate formulas are
For FY and grabs only last two digits of year
RIGHT(YEAR(DATE(YEAR(D5),MONTH(D5)+(10-1),1)),2)
For Period (gives me a two digit Period
TEXT(CHOOSE(MONTH(D5),4,5,6,7,8,9,10,11,12,1,2,3),"0#")
For Week
WEEKNUM(D5,1)-WEEKNUM(DATE(YEAR(D5),MONTH(D5),1),1)+1)
I believe I have a solution for you. Discussion to follow, but here's the full formula:
=CONCAT("FY",RIGHT(YEAR(D5+91+WEEKDAY(DATE(YEAR(D5),10,1))),2),"P",TEXT(IF(MONTH(D5+(7-WEEKDAY(D5)))<>MONTH(D5),IF(MONTH(D5)=9,1,CHOOSE(MONTH(D5),5,6,7,8,9,10,11,12,1,2,3,4)),CHOOSE(MONTH(D5),4,5,6,7,8,9,10,11,12,1,2,3)),"0#"),"W",ROUNDUP(((D5-IF(MONTH(D5+(7-WEEKDAY(D5)))<>MONTH(D5),DATE(YEAR(D5),MONTH(D5)+1,1)-WEEKDAY(DATE(YEAR(D5),MONTH(D5)+1,1))+1,DATE(YEAR(D5),MONTH(D5),1)-WEEKDAY(DATE(YEAR(D5),MONTH(D5),1))+1))/7)+0.01,0))
One issue is that this still calculates 2/2/2020 the way you said was incorrect. When I verify it against a calendar, though, it seems that FY20P05W02 should be correct. If the week that includes the first of the month begins a new pay period, that would mean 2/1/2020, falling on a Saturday, would be the last day of fiscal week 1. That would make 2/2/2020 the first day of fiscal week 2.
To calculate fiscal year, I used RIGHT(YEAR(D5+91+WEEKDAY(DATE(YEAR(D5),10,1))),2). Since you can count on there always being 91 days from the beginning of October to the end of December, it helps with this calculation. In your formula, you had MONTH(D5)+(10-1), which would push you 9 months out past the month in D5. This explains why your result for 4/5/2020 was off by a year.
Fiscal period was a bit trickier, requiring a couple nested IF statements. I used IF(MONTH(D5+(7-WEEKDAY(D5)))<>MONTH(D5) first to account for days at the end of the month that would fall into the next fiscal period, then IF(MONTH(D5)=9 to account for the few days at the end of September that might fall into the next fiscal year. Days at the end of September would default to 1, days at the end of a month that are included in the next fiscal period use the first CHOOSE function (they need the next month's number), and everything else gets the CHOOSE function as you wrote it.
The fiscal week took a bit more, but in the end I evaluated the beginning of the current fiscal month and subtracted it from the date in D5, then divided by 7 and added 0.01 so that even numbers would round up correctly.
I tested this out over a few years of dates and it seemed to be functioning correctly, but let me know if you have questions or issues.
One thing to consider when using WEEKNUM is that you'll have a week that is counted twice at the beginning of the year unless you use option 21 or ISOWEEKNUM. These give the same result as each other, and ensure that only one week number is assigned to any given day, no matter the year.
Question is as in title.
I have a cell, "D4", with the date "09/07/2016" in it. Adjacent cell has formula "=weeknum(D4,1)". The output of this function is "28". But on a Sunday-Saturday basis, Saturday the 9th of July wasn't in week 28 - it was in week 27.
I thought this might be something to do with Saturday/Sunday and when the week starts and finishes, etc, so I tried multiple different dates from last week - Monday the 4th, Tuesday the 5th, Wednesday the 6th, etc. In each case, "weeknum" returns a value of "28".
I only noticed the problem because I have a macro which uses the value of the cell with the week number to look for a spreadsheet saved by our accounts team on a weekly basis. As they have - correctly - saved the spreadsheet as "week 27", it didn't work. I initially assumed that the accounts team were wrong, but I checked online and they are correct.
How could this happen? Surely Excel can't be wrong and I must have made a mistake of some sort?
I know that there is an issue with Excel not following ISO standards for when weeks 53 and 1 begin and end, but I don't see how that could affect a mid-year week.
It did occur to me that the issue might be to do with UK versus US date formatting. But, of course, the 7th of June wasn't in week 28 either.
That all is documented in WEEKNUM.
There are two systems used for this function:
System 1 The week containing January 1 is the first week of the
year, and is numbered week 1.
System 2 The week containing the first Thursday of the year is the
first week of the year, and is numbered as week 1. This system is the
methodology specified in ISO 8601, which is commonly known as the
European week numbering system.
Syntax
WEEKNUM(serial_number,[return_type])
Return_type Week begins on System
...
21 Monday 2
So =WEEKNUM("09/07/2016",21) will calculate as defined in ISO 8601 since Return_type 21 is the only one with System 2.
ISOWEEKNUM
=ISOWEEKNUM("09/07/2016")
will also do it.
=ISOWEEKNUM(a2)-1 returns the correct week for me, the same as =WEEKNUM(a2,21)-1
I'm wondering if this is possible. I am creating a spreadsheet to track project due dates. Each project must be completed by the 30th calendar day, but must be turned in on a business day.
Currently, I am just adding 30 days to the start date but this means some due dates aren't always accurate. For example, if the 30th day is Saturday, April 2nd, then the real due date would be Friday April 1st.
Is there a way to construct a conditional such that the due date equals the 30th calendar day, unless that falls on a weekend / holiday, where it then falls on the next earliest business day?
I've been struggling to figure out a way to do this.
For English settings in Excel, with a date in A1, in B1 enter:
=IF(TEXT(A1+30,"DDDD")="Sunday",A1+28,IF(TEXT(A1+30,"DDDD")="Saturday",A1+29,A1+30))
This simple-minded approach only handles Saturdays and Sundays, not arbitrary holidays.
I would prefer more elegant way like using WORKDAY.INTL
=WORKDAY.INTL(A2+31,-1,1,E2:E)
Explanation: start date + 31 days (1 day more than maximum calendar days)
then subtract 1 working day - going to last previous working day
Reason: because this formula does know when are weekends (by using variables) and also knows to skip hollydays by a custom list.
here is an example sheet you can use
Revised after comment:
Try this:
=(A4+30)+CHOOSE(WEEKDAY(A4+30),1,0,0,0,0,0,-1)
Your date, in A4, + 30 days, then add an amount of days until the next workday. If A4 + 30 is a Saturday it will subtract 1 day, a Sunday will add 1.
I have an Excel sheet where someone types in the date for a yearly bill. I need to know how many times we need to pay that bill between 2 dates.
For example if a bill is due every year on May 31st, the user will type in 5/31/2014. I need to know how many time we will pay that bill between 5/15/2014 and 5/15/2018. (The between dates will change). I can't just take the number of years between the start and end dates because in the example above the start and end dates could be 6/1/2014 and 5/30/2018, in which case I only have to pay the bill in 2015, 2016, and 2017, which makes 3 times.
I have this formula which calculates the number of times a certain day occurs between 2 dates: SUMPRODUCT(--(DAY(ROW(INDIRECT($Q$2&":"&$R$2)))=F4))(Q2 is the begin date, R2 is the end date, and F4 has the day of the month) But I can't figure out how to get this to work for a month and day.
Assuming the specific date in G4 you can use this version
=SUMPRODUCT(--(TEXT(ROW(INDIRECT($Q$2&":"&$R$2)),"ddmmm")=TEXT(G4,"ddmmm")))
Suppose that I open an automatic rollover time deposit (ARO TD) account in a bank on January 17, 2017 (the value date). The funds in this account must be held for 3 months (the tenor). Since it's an ARO TD, the maturity date will be automatically renewed with no action required by me if I choose to do nothing. Today's date is July 18, 2017. So, my account will mature on October 17, 2017. If I open it on January 19, 2017, it will mature on July 19, 2017, and so on.
How do I track the maturity date of my account in Excel with only using inputs: deposit period and value date? Meaning, the maturity date will continually update to the next period each time it matures. I'm able to find the Excel formula for this:
=IF(EDATE(B2,A2*CEILING(DATEDIF(B2,TODAY(),"M")/A2,1))<TODAY(),EDATE(B2,A2*(1+CEILING(DATEDIF(B2,TODAY(),"M")/A2,1))),EDATE(B2,A2*CEILING(DATEDIF(B2,TODAY(),"M")/A2,1)))
The above formula works perfectly but it's too long. Could anyone here come up with a nicer and shorter formula than this?
You can use the DATEDIF function to do this. For reasons I don't understand, Excel doesn't suggest it when you're typing, but it exists and is documented.
DATEDIF is useful because you're interested in the number of months between dates. The earlier date of interest is the value date; the later date is today (actually yesterday, because as in your first example you want the date to tick on on the expiry date).
Once you have this number of months, you can get the exact number of tenors that is, add one, and then add that many months to the value date.
A formula is actually easier than the above text!
Your C2 cell should be:
=EDATE(B2, A2 * (FLOOR( DATEDIF(B2, TODAY()-1, "m") / A2, 1) + 1))
Working outwards from the middle, the DATEDIF gets the number of months from the value date to yesterday, we divide it by the tenor and floor to get the number of tenor periods that have passed, we add one to get the target number of tenor periods, we multiple by the tenor to get the number of months to add, then finally EDATE does the month-adding.
The result will be a date serial (eg 43025) so will need appropriate cell formatting.
