Excel Date Calculation with Rounding - excel

I am currently working on a report where i want to find out the months between 2 dates. I currently have this
=(DATEDIF(U224,V224,"m")+1)
However i want it to add another element where if the initial date is on or before the 15th of the month it will round down if it is 16th and after it will round up the month.
For example first date is 13th February and second date is 31st June. It will bring back 5 months. However if the first date is 20th February it will bring back 4 months.
Thanks in advance

It sounds like you are saying:
=IF(DAY(U224)<16,DATEDIF(U224,V224,"m"),DATEDIF(U224,V224,"m")+1)

How to get Excel to find the next Tuesday when the date in a cell is Monday, Friday, Saturday, or Sunday

I'm setting up a spreadsheet to calculate dates based off of one trigger date. If one of the subsequent dates is not a Tuesday, Wednesday, or Thursday, I need Excel to find the date of the next Tuesday. (In my office, certain meetings can only happen Tuesday through Thursday, so if the calculated date falls on a Monday or a Friday, I'd like Excel to give me the next Tuesday.)
I'm trying to use IF and WEEKDAY together, and I'm pretty sure something is wrong with how I wrote the "or" logic. Here's what I have:
=IF(WEEKDAY(D9,1)=NOT(OR(3,4,5)),D9+7-WEEKDAY(D9+7-3),D9)
But the formula returns false every time and gives me the date in the cell itself.
With a date in A1, use:
=CHOOSE(WEEKDAY(A1),A1+2,A1+1,A1,A1,A1,A1+4,A1+3)
(almost as easy as a VLOOKUP())
=IF(MOD(A1-1,7)>2,A1+2-MOD(A1-1,7)+7,A1+2-MOD(A1-1,7))
A1 is your trigger date

Calculate the first week of year which starts from first Sunday of every Feb

I have an issue here. I want to calculate the week nummber of first sunday of business year. Where I work their calendar starts on February 1st. To calculate i have a column A2 in excel which has the date in mm/dd/yyyy format. I want to generate the corresponding fiscal week for the column.
example of my result set:
for 2/1/15 the week of year number should be 1
For 2/7/16 the week number of year should be 1
I tried the below formula, but its starting the week from the first day of the fiscal year and not the first sunday of the year.
=INT((A1-WEEKDAY(E9165)-DATE(YEAR(A1+7-WEEKDAY(A1))-(MONTH(A1)<2),2,1))/7)+2
Please help...

Assuming that your work years always start on the first sunday after February 1st:
=IF(WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1)<=0,52+WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1),WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1))
We first determine the week number of the date starting from the first Sunday of February. To do this I have used WEEKNUM()-WEEKNUM(02/01/SAMEYEAR) taking 1 day from the date to force week 1 as Excel begins counting from week 0 by default. Using IF() we state that if the outcome is 0 or less then add the result to 52, which will give us the correct result for dates in January as they produce negative values.
Edit - Very long formula but gives you the week of the quarter in Q1 W1 format:
=SUBSTITUTE(CONCATENATE("Q",INT(IF(WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1)<=0,52+WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1),WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1))/13)+(IF(INT(IF(WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1)<=0,52+WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1),WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1))-INT((IF(WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1)<=0,52+WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1),WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1))/13))*13)=0,0,1))," W",INT(IF(WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1)<=0,52+WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1),WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1))-INT((IF(WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1)<=0,52+WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1),WEEKNUM(A1)-WEEKNUM(DATE(YEAR(A1),2,1)-1))/13))*13)),"W0","W1")
Apologies for the length, I tried multiple methods to try to find a neater solution, but this was all that I could get to work. It would be a lot neater if there were multiple columns used.
Use this formula:
=IF(A1>=IF(WEEKDAY(DATE(YEAR(A1),2,1),1)=1,DATE(YEAR(A1),2,1),DATE(YEAR(A1),2,7-WEEKDAY(DATE(YEAR(A1),2,1),1)+2)),ROUNDUP((A1-IF(WEEKDAY(DATE(YEAR(A1),2,1),1)=1,DATE(YEAR(A1),2,1),DATE(YEAR(A1),2,7-WEEKDAY(DATE(YEAR(A1),2,1),1)+2))+1)/7,0),ROUNDUP((A1-IF(WEEKDAY(DATE(YEAR(A1),2,1),1)=1,DATE(YEAR(A1)-1,2,1),DATE(YEAR(A1)-1,2,7-WEEKDAY(DATE(YEAR(A1)-1,2,1),1)+2))+1)/7,0))
Way late to the party but was looking for the answer and found this thread. Ended up play around with the function myself and it's much easier to just deduct the dates; =WEEKNUM("date"- days you wish to offset)
Ex; If cell A1 holds my date, 2/1/2021 I wish to convert; =WEEKNUM(A1-31) result "1".

Access/Excel VBA: Getting the two dates corresponding to last week

I think I can do this with a loop but since I am using this in conjunction with MS Access I wondered if there was a quick way to do this.
Right now it is April 3rd, 2014. I want to be able to return the dates corresponding to the Sunday and Saturday that bookend the previous week.
So for example that would be March 23rd (Sunday) through March 29th (Saturday) last week.
In Excel formulae:
=TODAY()-WEEKDAY(TODAY())-6 'Sunday of last week
=TODAY()-WEEKDAY(TODAY()) 'Saturday of last week
=TODAY()-WEEKDAY(TODAY())+6 'Friday of current week
In VBA:
Date()-Weekday(Date())-6 'Sunday of last week
Date()-Weekday(Date()) 'Saturday of last week
Date()-Weekday(Date())+6 'Friday of current week
Previous Sunday:
=A1-WEEKDAY(A1)-6
Saturday
=A1-WEEKDAY(A1)

Excel display nth day of current month

I have a list of recurring bills. Some are on the 1st of every month, and some are on the 15th or 16th etc. What I want to be able to do is display this day within the current month. So if it is February, and the bill recurs on the 9th every month, my cell will show 02/09/12, and if it was march, it would show 03/09/12. Is there a formula or macro to accomplish this?
Found it to be: =DATE(YEAR(TODAY()),MONTH(TODAY()),18)
If you have the number 9 in A1 this formula will show the 9th of the current month (whether that be in the future or the past)
=TODAY()-DAY(TODAY())+A1
edate(start-date),1)
ie edate(B3,1)
b3= 1/5/13
Result = 5th of 1 month later - 2/5/13
3 for quarterly, 12 for annual

Excel function to determine the last Friday in a month

I'm looking for an Excel function to return the last Friday in a month for a given date.
ie: Any date in the month as input will give the date of the last Friday as output.
14-July-09 should give 31-July-09
7-March-05 should give 35-March-09
Building on #Toomas answer above, I had to make some amendments for Excel 2007, but came up with the following:
=EOMONTH(A1,0)-MOD(WEEKDAY(EOMONTH(A1,0))+1,7)
Which is assuming that the WEEKDAY returned for Friday is 6 and then applying a shifted MOD 7 to achieve the correct day.
Try this formula:
=IF(WEEKDAY(EOMONTH(A5;0);16)=7;EOMONTH(A5;0);EOMONTH(A5;0)-WEEKDAY(EOMONTH(A5;0);16))
Enter to A5 date value of which you are looking for the last Friday in a month.
The following formula achives this for a date in cell A1:
=DATE(YEAR(A1),MONTH(A1)+1,0)+MOD(-WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,0),2)-2,-7)
I came here looking for the formula to get the most recent Friday in the past which turned out to be =TODAY()-WEEKDAY(TODAY())-1
In case anyone needs to do this for next year (or future years):
=EOMONTH(DATE(YEAR(TODAY())+1,MONTH(TODAY()),1),0)-MOD(WEEKDAY(EOMONTH(DATE(YEAR(TODAY())+1,MONTH(TODAY()),1),0))+1,7)
Here's one that will show the last Friday of the current month.
And if the date is in the past it will show you next month's last Friday.
And if it's December right now, it'll show you next year's January's Friday.
=IF(DATE(YEAR(TODAY()),MONTH(TODAY())+1,0)+MOD(-WEEKDAY(DATE(YEAR(TODAY()),MONTH(TODAY())+1,0),2)-2,-7)>=TODAY(), DATE(IF(MONTH(TODAY())+1>12,YEAR(TODAY()+1),YEAR(TODAY())),MONTH(TODAY())+1,0)+MOD(-WEEKDAY(DATE(YEAR(TODAY()),MONTH(TODAY())+1,0),2)-2,-7), DATE(IF(MONTH(TODAY())=12,YEAR(TODAY())+1,YEAR(TODAY())),MONTH(IF(MONTH(TODAY())=12,1,MONTH(TODAY())))+1,0)+MOD(-WEEKDAY(DATE(IF(MONTH(TODAY())=12,YEAR(TODAY())+1,YEAR(TODAY())),MONTH(IF(MONTH(TODAY())=12,1,MONTH(TODAY())))+1,0),2)-2,-7))
You can try
=DATE(YEAR(A1),MONTH(A1)+1,1)-1+CHOOSE(WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,1)-1),-2,-3,-4,-5,-6,0,-1)
to find the last friday of the month. Assumes A1 has the date.
Hey the formatting is outdated so ill show what I came up with:
=EOMONTH(A1;A2)-(WEEKDAY(EOMONTH(A1;A2);15)-1)
[A1] is an interval of months later, from [A2] the stating date, that the result date should be.
We have some equipment that need maintenance last Friday of the month, an number of months since last Maintenace.
EOMONTH(A1;A2): we find the date, of the last day, of target month.
WEEKDAY([Date];15): assign a number for day of the week.
[15] makes Friday the value 1 and Thursday the value 7.
so if the last day of the month is Friday, the calculation would be:
[Date]-(1-1) = [Date] therefor the date won't change.
[Date] in my original code example, is the last day of the target month: [A2] date + [A1] number of months later.
if the last day is Wednesday, we want it to subtract 5 days: [Date]-(6-1) = [Date]-5
As a sidenote:
=WORKDAY(A2+1;-1;[hollydays])
will round a date back to the earlier Workday if it lands in a weekend or holyday
[holyday] can be an area of cells with predefined dates to skip eg: [$C$1:$C$20].
$ is so the area won't change when you extend the function to other cells.
if you don't care about holydays use =WORKDAY(A2+1;-1)
Awesome! Basically, like trying to find the first or second Monday of the month,
=DATE(TheYear,5,1)+CHOOSE(WEEKDAY(DATE(TheYear,5,1)),1,0,6,5,4,3,2)
which returns the first Monday of the month, in this case May
but to find the last weekday of the month, in the formula, you start with the next month and subtract
=DATE(TheYear,6,1)-1+CHOOSE(WEEKDAY(DATE(TheYear,6,1)),-6,-5,-4,-3,-2,-1,0)
which returns the last Monday of May
I have a cell that I named TheYear, in which I enter the year I'm working with, but you can point to whatever cell you have the year you want (e.g. A1).
I don't know why the pointers to the days of the week are in reverse order but to find the day (e.g. Tuesday instead of Monday), change the order of those numbers but they have to stay in order. For example, 4th Thursday of November:
=DATE(TheYear,11,1)+21+CHOOSE(WEEKDAY(DATE(TheYear,11,1)),4,3,2,1,0,6,5)
=EOMONTH(TODAY(),0)-WEEKDAY(EOMONTH(TODAY(),0))-1
This gives the last Friday of this month. You can replace both instances of Today() with any date you like or a cell reference that has a date to get the last Friday in any other month.
=WORKDAY.INTL((EOMONTH(A4,0)+1),-1,"1111011")
