I'm trying to put together an excel spreadsheet to show the day-by-day impact of stays by 3rd country citizens in the EU's Schengen area (it's a fairly complex rolling 180 day window). At the moment, I have a column with every day from a start date (so lots of rows) and another where I enter a 1 if there was a stay in a Schengen country for that day. Then other columns calculate when the 180 day period started and how many days have been in Schengen for that day.
It's a bit of a faff having to enter a 1 for every day away. I'd like to have another worksheet where I simply enter the start and end dates of (an arbitrary number of) each stay and then the calculation spreadsheet simply works out if each date falls within a stay or not. Working out whether a date falls within one date range is pretty straightforward, but working out if it falls within several date ranges isn't obvious to me. Any suggestions please?
After a very fair comment, here's a couple of images that hopefully illustrate what I'm trying to do (please ignore the colours).
Example of date ranges, but the number of these should be arbitrary:
The calculated sheet - currently I have to enter the 1s individually whereas I'd like them evaluated from the date ranges:

oversimplified i have two columns: Date and Text; I want to check my current amount of vacation days based on the first date in row 2, so i came up with the following formula:
="Available vacation days: "&YEARFRAC(A2;TODAY())*12*(25/12)
I calculate the fraction of the year based on the first date and todays date, multiply it by 12 to get months and multiply it again by the total amount of vacation days in my contract per month. Now i got another formula to collect me all cells in column B containing "Vacation", pretty straight forward:
=COUNTIF(B:B;"Vacation")
Now the interesting part - i got the formula who gives me a boolean if a datetime matches the 24th or 31st of december:
=AND(OR(DAY(A53)=24;DAY(A53)=31);MONTH(A53)=12)
I want to count vacation days happening on a 24th or 31st of december as a half-vacation day (0.5), and otherwise fully (as a 1). Then i want to combine my first statement with this result and subtract the used vacation days. I read about VLOOKUP and XLOOKUP but am unsure if this fits this purpose. I want to avoid having an extra column with my boolean returns and rather have this one cell giving me all the information combined.
Without introducing another column, and using DAY and MONTH
It's nearly impossible, and just unnecessarily so...
Please reconsider this, what will happen if you want to add 4th of July as a holiday?
Your formula =AND(OR(DAY(A53)=24;DAY(A53)=31);MONTH(A53)=12) only works for 1 row at a time. So, we can't ever use it with a list, because you will get the whole list as a result every single time. You can't divide them into smaller lists and join them together, there is no such functionality without VBA.
In the future, do not set arbitrary constraints like "no additional columns", you can hide them if you don't like them. And if you don't need them, remove unnecessary rows like non-vacation rows. They are irrelevant, so why not separate the two.
Just to prove my point, here's the solution you wanted:
Solution
=COUNTIFS(B2:B9;"Vacation") - (COUNT(IFERROR(FILTER(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12);DAY(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12))=31);0))+(COUNT(IFERROR(FILTER(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12);DAY(FILTER(FILTER(A2:A9;B2:B9="Vacation");MONTH(FILTER(A2:A9;B2:B9="Vacation"))=12))=24);0))))*0,5
It works, but it's a pain to read, use and maintain.
A2:A9 refers to the dates column
B2:B9 refers to the text column
So in the future, the last thing you want to do is set arbitrary constraints. Furthermore, why use functions like MONTH and DAY when we can just read the text? That way you could even create a table of holidays to search for instead. That will be no fun task with this setup. (Oh, and if it's because of the year, just strip it away from the text when you want to know only the month and day.
Best of luck!
I have a column that needs split based on "morning" and "evening" although the morning and evening times move every day (it's based on sidereal day). Calling them morning and evening is a little deceiving though because eventually the time will creep into the next day and I want to keep the groups distinct. It is more accurate to call them group 1 and group 2. It just so happens that they are around 12 hours apart so it looks like you can just separate based on time of day but once the later group creeps into the AM hours, it would start to get counted as "morning" and the earlier group would roll into the afternoon and be counted as "afternoon" See screenshot below for example data.
I need them split so I can perform operations on the value column so I can distinguish the values in the first group from the values in the second group. I thought of doing some sort of flip flop algorithm based on the previous cell but there may be a more elegant way to do it. Also, it's not shown on the example data but sometimes the day may skip but the times more or less continue in the same pattern of increasing by 3-5 minutes each day.
A date with a time stamp is stored as a number in Excel. Days are stored as whole numbers, time is stored in decimals. So, disregarding the date part, look at the decimal of the number and determine if that is before or after the time you want.
0.5 for example is midday, or 12 noon. So if the decimal part of A1 is less than 0.5, the time stamp would be in the morning.
=if(A1-int(A1)<0.5,"before noon","after noon")
It is not clear from your question how sidereal relates to the data in your sample.
I have the following worksheet:
The grid is filled with the following formula (this example is from cell H4) that populates the grid based on inputs from the table on the left, =IF($A4="","",IF(AND($E4="Daily",H$2>=$D4,H$2<=$G4),IF(RIGHT($F4,2)="30",LEFT($F4,LEN($F4)-2)&"/",IF(RIGHT($F4,2)="00",LEFT($F4,LEN($F4)-2),$F4)),IF(AND($E4="Weekly",H$2>=$D4,H$2<=$G4,TEXT(H$2,"DDD")=TEXT($D4,"DDD")),IF(RIGHT($F4,2)="30",LEFT($F4,LEN($F4)-2)&"/",IF(RIGHT($F4,2)="00",LEFT($F4,LEN($F4)-2),$F4)),IF(AND($E4="Bi-Weekly",H$2>=$D4,H$2<=$G4,MOD($D4+14,H$2)=0),IF(RIGHT($F4,2)="30",LEFT($F4,LEN($F4)-2)&"/",IF(RIGHT($F4,2)="00",LEFT($F4,LEN($F4)-2),$F4)),IF(AND($E4="Monthly",H$2>=$D4,H$2<=$G4,TEXT(H$2,"MM/DD/YYYY")=CONCATENATE(TEXT(H$2,"MM"),"/",TEXT($D4,"DD"),"/",TEXT($D4,"YYYY"))),IF(RIGHT($F4,2)="30",LEFT($F4,LEN($F4)-2)&"/",IF(RIGHT($F4,2)="00",LEFT($F4,LEN($F4)-2),$F4)),IF(COUNTIF('PowerPoint Gantt'!$A$5:$A$12,$A4)=1,IF(H$2=VLOOKUP($A4,'PowerPoint Gantt'!$A$5:$E$12,5,FALSE)+31,"R",""),""))))))
The only part of the function that isn't working is the Bi-Weekly selection. I can't figure out how to get recurring entries. I can get the start date and one 14 day period after. I've tried using the CEILING function also but still only gets me the next 14th day marked, instead of every 14th day. And ideas?
In your rule for Bi-Weekly meetings, it seems that
MOD($D4+14,H$2)=0
should be replaced with
MOD(H$2-$D4,14)=0
The latter takes the difference between the starting date and the actual date and checks to see if that can be divided by 14, the number of days in 2 weeks.
Your rule for Weekly meetings could be approached similarly, which seems simpler to me than a rule based on the name of the day, like you are using now.
In assessing how many agents can be added to certain times of day without exceeding the number of seats in the call center, I'm trying to discern how many agents are scheduled for each half hour interval on each day of the week.
Using the =SUMPRODUCT(((A$2:A$1000<=D2)+(B$2:B$1000>D2)+(A$2:A$1000>B$2:B$1000)=2)+0) formula I've been able to identify how many total agents work for each interval, however this doesn't take the day of week into account.
I currently have my spreadsheet setup this way:
K is the start time of the shift, L is the end time of the shift, M to S pulls data from another sheet that shows a 1 if the agent works on that day of the week and 0 if they do not, and then U has all the time intervals listed out. In the example, it's cut off but the columns continue down as needed. U goes to 49 and I've just been using a range from 2 to 500 for the others as we currently do not have that many shifts and I'm leaving space for the moment.
After some Googling, I tried =SUMPRODUCT(--(M2:M500="1"),(((K$2:K$1000<=U2)+(L$2:L$1000>U2)+(K$2:K$1000>L$2:L$1000)=2)+0)) but it only returns #VALUE! so I'm not sure what I'm doing wrong.
Any suggestions of how I can make this work? Please let me know if more information would be useful. Thanks.
=sumproduct(($K$2:$K$1000<=U2)*($L$2:$L$1000>=U2))
That will count the number of occurrences where the start time is less than or equal to the time in U2 AND the end time is greater than or equal to U2. It will check time from row 2 to row 1000. Any time one condition is checked and its true the comparison will result in value of TRUE and FALSE when its not true. The * act like an AND condition while at the same time converts TRUE and FALSE values to 1 and 0. So both conditions have to be true for a value of 1 to result. Sumproduct then totals up all the 1 and 0 to get you a count.
In order to consider the days of the week, you will need one thing to be true. Your headers in M1:S1 will need to be unique (which I believe they are). You will need to either repeat them in adjacent columns to M or in say V1 you have a cell that can change to the header of the day of the week you are interested in. I would assume the former so you can see each day at the same time.
In order to do this you want to add more conditions and pay attention to you reference locks $.
In V2 you could use the following formula and copy down and to the right as needed:
=sumproduct(($K$2:$K$1000<=$U2)*($L$2:$L$1000>=$U2)*(M$2:M$1000))
UPDATE #1
ISSUE 1 Time ranges ending the following day (after midnight)
It is based on the assumption that the ending time is later than the start time. When a shift starts at 22:00 and end at 6:30 as an example, our mind says that the 0630 is later than 22:00 because it is the following day. Excel however has no clue that 0630 is the following day and without extra information assumes it to be the same day. In excel date is stored as an integer and time is stored as a decimal. When you only supply the time during entry it uses 0 for the date.
In excel the date is the number of days since 1900/01/00. So one way to deal with your time out is to add a day to it. This way excel will know your out time is after your in time when the hour is actually earlier in the day.
See your sample data below.
Using your sample data, I did a straight copy of the value in L and placed it in M (=L3 and copy down). I then changed the cell display format from time to general. This allows you to see how excel sees the time. Note how all the time is less than 1.
In column N I added 1 to the value when the out time was less than the in time to indicate that it was the following day and we had not actually invented time travel. I also used the trick of a math operation will convert a TRUE/FALSE result to 1 or 0 to shorten the equation. I used =M3+(L3<K3) and copied down. You will notice in the green bands that the values are now greater than 1.
In the next column I just copied the values from N over using =N3 copied down, and then I applied just a time display format for the cell. Because it is only time format, the date is ignored and visually your time in column O looks the same as column L. The big difference is excel now knows that it is the following day.
you can quickly fix your out times by using the following formula in a blank column and then copying the results and pasting them back over the source column using paste special values.
=M2+(L2<K2)
The next part is for your time check. When looking at the 12:00 time you need to look at 1200 of the current day incase a shift started at 12:00 and you need to look at the 1200 period of the following day. In order to do that we need to modify the the original formula as follows:
=sumproduct(($K$2:$K$1000<=$U2)*($L$2:$L$1000>=$U2)*(M$2:M$1000)+($K$2:$K$1000<=$U2+1)*($L$2:$L$1000>=$U2+1)*(M$2:M$1000))
Note that the + in the middle of (M$2:M$1000) + ($K$2:$K$1000<=$U2+1)? This + acts like an OR function.
Issue 2 Time In/Out 15 minute increments, range 30 minute increments
You may be able to achieve this with the ROUNDDOWN Function or MROUND. I would combine this with the TIME function. Basically you want to have any quarter hour start time be treated as 15 minutes sooner.
=ROUNDDOWN(E3/TIME(0,30,0),0)*TIME(0,30,0)
Where E3 is your time to be converted
So your formula may wind up looking something like:
=sumproduct((ROUNDDOWN($K$2:$K$1000/TIME(0,30,0),0)*TIME(0,30,0)<=$U2)*($L$2:$L$1000>=$U2)*(M$2:M$1000)+((ROUNDDOWN($K$2:$K$1000/TIME(0,30,0),0)*TIME(0,30,0)<=$U2+1)*($L$2:$L$1000>=$U2+1)*(M$2:M$1000))
similar option could be used for the leaving time and rounding it up to the next 30 minute interval. In which case just use the ROUNDUP function. Though I am not sure it is required.
I would like to generate a mock time series quarterly dataset from, say, 2000-2016 for a variable (quarterly credit growth) that averages around a certain value (say, 30%). Can anyone give a suggestion on how to do this in principle?
Edit: what I was implying were the actual data values for each time period, i.e. data with a certain mean and variance.
Found a solution with a code in Matlab, for anyone interested, see below in answers.
Excel approach:
You can make column A your date list. In A1, or A2 or more if you have header rows, you will have to seed your list by providing the first start date. Lets assume you put your seed date in A2. I would then go about adding 3 month to you start date using a formula, and copy down until you have hit your desired date. In order to add the 3 months I would use the following in A3.
=date(year(A2),Month(A2)+3,day(A1)
that will give you the first day of the month every 3 months. If you want the first day of the month every 3 months, set the day to 1 like so:
=date(year(A2),Month(A2)+3,day(A1)
And end of month could be calculated as:
=eomonth(date(year(A2),Month(A2)+3,day(A1)),0)
however I would prefer to do the end of month calculation based on the row you are in so I would do it more like:
=EOMONTH($A$2,(rows($A$2:A3)-1)*3)
