I have 2 columns with:
Night shift start: 19:00
Night end: 04:00
And I have some date columns with for each day..
Work started: 07:30
Worked ended: 22:00
I want to get the number of hours as a decimal that is between the night shift start and night end. I need to calculate the number of "night shift hours" for worked hours.
From comment: I do not want to get the total number of hours. I want to calculate the number of "night shift hours" and that is hours between 19:00-04:00
=IF(B1-A1 < 0, 1-(A1-B1),( B1-A1))
Assuming that cell A1 contains start, B1 contains end time.
Let me know, if it helps OR errors.
Time without date is not enough to do the subtraction considering the start can be the night before today.
Are you OK to try VBA?
EDIT: The formula is meaningful within 12 hour limit. I will see if it can be made simpler.
Given start time in B5 and end time in C5 this formula will give you the decimal number of hours that fall in the range 19:00 to 04:00
=MOD(C5-B5,1)*24-(C5<B5)*(19-4)-MEDIAN(C5*24,4,19)+MEDIAN(B5*24,4,19)
format result cell as number
just substract the two dates to get the difference in days, and multiply by 24 to get the difference in hours
=(B1-A1)*24
this is correct when both B1 and A1 contain a datetime value, but in case your cells contain just a time value, with no day value, and given that the calculation spans the night (there is a day change in between) you need to add one day to the difference:
=IF(B1<A1,1+B1-A1,B1-A1)*24

I would like to have a formula which will tell me if a time in a cell is between 2 separate vlaues in other cells and to return a value if so.
I have already created the below code but this is not returning any values back at all.
=IF(AND(F4>=$R$1,F4<P1),"Night Shift",IF(AND(F4>=$P$1,F4<$Q$1),"AM Shift",IF(AND(F4>=$Q$1,F4<$R$1),"PM Shift","")))
In this example the cell values are (P1 = 06:00, Q1 = 14:00, R1 = 22:00). The value in the F4 is 00:31:38.
Any help would be appreciated.
Your first AND needs to adjust a little.
Excel sees TIME as a fraction of 1 whole day. So 00:31:38 though you meant it to be the next day from 22:00, Excel does not know that and as such will not see it greater than 22:00
We also do not need to test for the Night Shift. It is the only option left if the time is not in one of the others:
=IF(F4<>"",IF(AND(F4>=$P$1,F4<$Q$1),"AM Shift",IF(AND(F4>=$Q$1,F4<$R$1),"PM Shift","Night Shift")),"")
You could also create a small table like such:
0 6:00 14:00 22:00
Night Shift AM Shift PM Shift Night Shift
Then use a HLOOKUP to return the correct value:
=HLOOKUP(F4,O1:R2,2,TRUE)
I took a slightly different path that Scotts.
A Night Shift occurs if the time is greater or equal to 10PM, OR is less than 6AM.
=OR($F$4<$P$1,$F$4>=$R$1)
An AM Shift occurs when the time is greater or equal to 6AM, AND is less than 2PM.
=AND($F$4>=$P$1,$F$4<$Q$1)
A PM Shift occurs when the time is greater or equal to 2PM, AND is less than 10PM.
=AND($F$4>=$Q$1,$F$4<$R$1)
Stick the three conditions together and you have:
=IF(OR($F$4<$P$1,$F$4>=$R$1),"Night Shift",IF(AND($F$4>=$P$1,$F$4<$Q$1),"AM Shift",IF(AND($F$4>=$Q$1,$F$4<$R$1),"PM Shift","")))
Edit
During testing I entered 00:00:00 in A1 and =A1+TIMEVALUE("00:01:00") in A2:A1440.
At 06:00:00, 14:00:00 and 22:00:00 the changeover in shift happened a minute later.
If, however, I manually typed in 06:00:00 the changeover happened on the hour. This seems to be because TIMEVALUE is calculating 6AM as 0.2499999 rather than 0.25.
=IF(OR(HOUR(NOW())>22,HOUR(NOW())<7),"NIGHT","")&IF(AND(HOUR(NOW())>6,HOUR(NOW())<15),"MORNING","")&IF(AND(HOUR(NOW())>14,HOUR(NOW())<23),"LATE","")
I know a bit late but simplifies everything without the need of using other cells (note there are different times used).
Night - 23-07
AM - 07-15
PM - 15-23
I'm trying to make an excel sheet where I only need to put in start and end time and excel chooses the correct pay rate and how many hours I've worked (already done) and outputs how much I've earned. So far I have a column (D) for the date of shift (DAY, day of month, Month, year) column for hours worked (E), column for start time and end time (F, G) I have already written the formula to calculate the hours worked but in Australia where I live my pay rate increases after 7 PM, and increases again after 12 AM. Is there a way to have excel automatically know that it needs to take the hours worked before 7 PM and multiply it by a 24.41, then the hours worked between 7 PM and 12 AM by 26.54 etc, if my shift starts for example at 5:30 pm and ends at 3 AM?
These are the different payrates at the different times: (Time is in cell A1, Pay rate is B1, etc)
Time Pay Rate
Regular $24.41
Mon-Fri 7pm-midnight $26.54
Mon-Fri 7midnight-7am $27.60
Saturday $29.30
Sunday $34.18
Public Holidays $48.83
Thanks in advance
Solutions to all of these type of questions use the standard formula for overlapping time periods
=max(0,min(end1,end2)-max(start1,start2))
The best way to do it IMO is to simplify it two ways
(1) By splitting any times that cross through midnight into two parts, one up to midnight and one from midnight onwards
(2) Using a lookup table to match the conditions (day of week and time of day) to the payscale.
Then use an array formula to do the lookup and calculation. Because you can't use MAX and MIN as above in an array formula, you have to write it out using if statements and the formula gets pretty long
=SUM((WEEKDAY(E2,2)>=PayRates!$A$2:$A$10)*(WEEKDAY(E2,2)<=PayRates!$B$2:$B$10)*24*PayRates!$E$2:$E$10*
IF(IF(G2<PayRates!$D$2:$D$10,G2,PayRates!$D$2:$D$10)-IF(F2>PayRates!$C$2:$C$10,F2,PayRates!$C$2:$C$10)<0,0,
IF(G2<PayRates!$D$2:$D$10,G2,PayRates!$D$2:$D$10)-IF(F2>PayRates!$C$2:$C$10,F2,PayRates!$C$2:$C$10)))
This has to be entered using CtrlShiftEnter
This is how my pay rates are arranged
NB When the finishing time of a pay rate is midnight, it is entered as 1 (you want it to be 24:00, but entering 24:00 just gives you the same as 00:00)
And this is the main sheet
With the following columns
A,B and C are your input.
Split
=B2<A2
StartDate1 and StartTime1 are just a copy of your input
EndTime1
=IF(Split,1,B2)
StartDate2
=E2+Split
StartTime2
00:00
EndTime2
=IF(Split,B2,0)
Total1
The main formula
Total2
The main formula copied across by four columns to give any pay for the second day when the shift goes through midnight.
Total
Total1+Total2
Public holidays can be added fairly easily.
I'm trying to make spreadsheet that calculate overtime hours as the following:
If the task started after 2pm the hour is calculated as an hour and a half
if the task started after 12 am the hour is calculated as 2 hours
I wrote the following formula in column E:
=IF(AND(B5>G1;B5<G2);D5*D1;D5*D2)
but I get false results where did I went wrong?
thank you
The problem with your formula is that you are thinking of 12:00 AM as midnight. or 24:00. If you look at G2 you will see 12:00 AM or (24:00) in Excel it is stored as 0. You logical check is checking to if anything is less than zero. Assuming that you are never dealing with negative time your result will always be false as no time is less than zero.
I would change your layout a bit and add a shift 3 where there is no overtime. What happens when someone starts at 9 AM?
IF you have to keep your layout as is, I would change your formula in cell D5 to read:
=HOUR(C5-B5)
And then make sure cells D1,D2,D5 and E5 are all general format since they are just numbers and not actual time.
Next set G2 equal to 08:00
change your formula in E5 to:
=IF(B5<G2,D5*D2,IF(B5>=G1,D5*D1,D5))
or
=D5*IF(B5<G2,D2,IF(B5>=G1,D1,1))
See if that gets you any further.
One thing to watch out for is that Excel stores time in a decimal format which can really throw you off. You may think your are dealing with 12 when you see 12:00 PM in a cell, but what excel really has stored in that cell is 0.5 as it is half way through the day. 24:00 does not exist Excel formulas will treat it as 0 if it is supplied as an input for formulas. VBA will not accept it. Valid Excel times range from 00:00 to 23:59.
now having said this if you are looking strictly at 8 hour shifts and are only concerned about start times, you could simply do an if statement saying IF(start time = shift 1 start time, then multiply by shift 1 rate, IF( start time = shift 2 start time, then multiply by shift 2 rate, no special rate))
something else to consider, if you are looking at actual start times, and a person starts in one shift but finishes during the next shift what happens?
I'm trying to calculate the number of hours between two date/times, excluding bank holidays and between 10pm and 10am.
I've got the Start Datetime in B3, and then End Datetime in G3. In SLA B13 - B22, I have a list of the bank holiday dates for 2015, and I am using the following forumal
=SUM(G3-B3-COUNTIFS(SLA!B13:B22,">"&B3,SLA!B13:B22,"<"&G3))
For some reason, I cant get this to exclude bank holidays, however I then also nee to take into account the 10pm - 10am bracket.
Can anyone help?
=NETWORKDAYS(B3;G3;SLA!B13:B22)*12
*12 because only 12 hours per day count (exclude time between 10 pm and 10 am)
I've tried your formula and it works fine for whole days for me, as long as you format the cell containing the formula as general or number to avoid formatting it as a date. It doesn't exclude weekends of course which presumably is what you want.
You might want to add 1 to make it inclusive, make > into >= and < into <= in case the start and end dates are bank holidays and multiply by 12 to get the result in hours:-
=(G3-B3+1-COUNTIFS(SLA!B13:B22,">="&B3,SLA!B13:B22,"<="&G3))*12
You could calculate the hours worked directly from datetime values: the basic formula would be:-
=(G3-B3)*24-(INT(G3)-INT(B3))*12
i.e. subtracting 12 hours for each complete day.
You could also exclude the holidays (if between the start and end dates):-
=(G3-B3)*24-(INT(G3)-INT(B3)+COUNTIFS(SLA!B13:B22,">"&B3,SLA!B13:B22,"<"&G3))*12
i.e. subtracting a further 12 hours for each day's holiday.
One more thing you could do is to apply an adjustment for start and end time to the Networkdays formula by adding:-
=MOD(G3,1)-MOD(B3,1)
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"))
