I have dataset of date and hours. I need to remove data before 06:00 and after 18:00 to each day. Is there any formula to do that automatically in excel?
If you have Excel 365 you can use the FILTER-function - together with the MOD - logic to retrieve the time part of a date. (you will find a lot of explanations about this topic on SO - 0.25 equals to 6:00 and 0.75 to 18:00):
=FILTER(tblData,(MOD(tblData[Date],1)>=0.25)*(MOD(tblData[Date],1)<=0.75))
I named my table tblData and the field that I am filtering on is Date. You might have to adjust this.

I have a problem that I would like to solve. I got data in excel, which are
in this form, basically I have number of hours from 0 to 8760 in a column in excel, which represent the whole year. And in another column I have "Power from PV" which corresponds to how much power does photovoltaic system produce in that specific hour. I would like to convert these hours to months, so I could make a graph of monthly production of power in a whole year. Is there some sensible way to do this in excel?
Thank you for any suggestions.
You need three things:
You need to know that 1 equals 1 day, so if you want to convert hours into date related information, you need to divide it by 24.
There is a function, called Date(), which gives the date, based on year, month and day, like =DATE(2022,1,1).
There is a function, called Month(), which gives the month number of a date.
So, in summary, you need something like:
=MONTH(DATE(2022,1,1) + A3 / 24)
Once you have this in a new helper column, you can start using the Subtotals basic Excel feature.
I have a pivot table with a lot of items currently grouped by date into quartiles and then months under that. My question is this, Our Financial year is not Jan to Jan so can I set up quartiles to reflect this? also our financial periods are not simply set months, they follow the months but are always full weeks around that. for example, P1 this year is 04/07/2015 - 07/08/2015. and Q1 would be 04/07/2015 - 02/09/2015.
Aside from manually grouping is there a way to set this up to happen automatically within Excel?
As stated by pnuts in the question's comments:
The most practical way may be to define the quarters (?) in your source data.
If you are at least using a Gregorian calendar, you may want to subtract an offset from your dates (i.e. # of days between 01-Jan-YYYY and DD-MMM-YYYY ... whereby the offset YYYY doesn't need to be the same as your date's YYYY). By this subtraction you get an "ordinal number" of the date within your business year.
[offset] =[FOY]-DATE(YEAR([FOY]),1,1)
So with your year starting on [FOY]=04-Jul-2015, you have an offset of of 184 days and a normalized date of
[date_normalized] = [current_date]-[offset]
So 04-Jul-2015 will be shrunk to 01-Jan-2015. Now the quarter easily calculates to
=CEILING(MONTH([date_normalized])/3,1)
... or =VALUE(MID("111222333444",MONTH([date_normalized]),1)) ... if you prefer
For your not-quite-months always being full weeks, I suggest to calculate a week number by
=MOD(CEILING(([date_normalized]+1)/7,1)-1,52)+1
to create a weekly reporting period 1 .. 52. With a further =CEILING(.../4,1) this can be converted to quasi-months having 4 weeks each.
In excel I currently have data in date time format
For example: "11/10/2007 8:40:58 PM"
I am trying to extract the date and if the time is PM, I add a day.
if the time is AM, the date remains the same.
So since the time is 8:40:58 PM I would want 12/10/2007.
Is there a way in excel to do such a thing using formulas?
Please consider using the following formula. This uses the fact that in Excel in its date-time code uses 1 to represent a full day and fractions to represent the time. If timestamp is in A1 then:
=INT(A1)+IF((A1-INT(A1))>=0.5,1,0)
Regards.
This one works for me.
=IF(A1>0.5, A1+1, A1)
In order to have it only return the date right click on column B, select "Format" the take your pick.
I have a feed of 30 minutes meter readings from MySQL to Excel sorted by the first column which is a datetime format, i.e 10-06-2015 00:00:00, 10-06-2015 00:30:00, 10-06-2015 01:00:00 etc.
Because the reading from 00:00:00 each day is actually data from the last 30 minutes of the day, I need the 00:00:00 reading to be the last row for the day rather than the first (as Excel is sorting by time order 00:00 is the default start of each day). Does anyone know how to format this in Excel so that the 10-06-2015 00:00:00 will come after the 10-06-2015 11:30:00 row and not after the 09-06-2015 11:30:00 row?
I don't think you are going to find a way to do that using just formats. Reason being that the format doesn't change the underlying value, which is what excel uses to do the sort in the first place.
I would suggest using a helper column in which you use a formula... maybe something like this:
=IF(A2-ROUNDDOWN(A2,0)=0,A2+0.99999,A2)
Where the first value of your time series is in A1... then copy the formula down and sort on the column B. This worked for me.
This sounds simple but I have been pulling my hair out trying to figure out a solution. Any help before I go bald would be great.
I need a formula which is able to
calculate the duration in (days, hrs, mins) between two date\time values (eg 05/12/2012 5:30 PM and say 07/12/2012 5:45 PM);
excluding weekends and holidays.
I would like the result of the formula to read as follows "e.g 2 Days 0 Hrs and 15 Mins".
Thanks

You can use NETWORKDAYS and NETWORKDAYS.INTL to achieve this
A bit of manipulation is required as these return net whole days:
Use these functions to calculate the number of non workdays, then subtract from the difference between start and end dates
=E3-D3-(NETWORKDAYS.INTL(D3,E3,"0000000")-NETWORKDAYS(D3,E3,$A$16:$A$24))
This returns the working day difference, where 1.0 = 1 day
NETWORKDAYS.INTL(D3,E3,"0000000") calculates whole days between the two dates (no weekends, no holidays)
NETWORKDAYS(D3,E3,"0000000",$A$16:$A$24) calculates whole working days days between the two dates (Sat/Sun weekends, holidays as per your list in $A$16:$A$24)
Difference in non-working days between the two dates.
E3-D3 is time between start and end date/times (1.0 = 1 day)
Use custom number formatting to display thye result in the format you require
d "Days" h "Hours" mm "Mins"
Note: this format won't work for negative values, you will need an alternative for when end date is before start date.
The following formula works like a treat with no additional formatting or manipulation.
To make it more stable I have turned all the holiday dates for UK 2012/13 into ‘Excel Serial Number’ format and placed them in an array bracket.
Replacing the "D5" in the formula with your cell reference for your course or metric "End Date" and "E5" with your course or Metric for "Completion Date".
=IF(E5<D5,"-"&TEXT(D5-E5,"h:mm"),NETWORKDAYS(D5,E5,({40910,41005,41008,41036,41064,41065,41148,41268,41269,41275,41362,41365,41400,41421,41512,41633,41634}))-1-(MOD(E5,1)<MOD(D5,1))&" days "&TEXT(E5-D5,"h:mm"))
