# Formula To Calculate How Many Hours Minus 30 Mins For Lunch

## If a person does a full day I want the formula to calculate how many hours minus 30 mins for lunch i.e. 7:30 - 4:00 = 8 hours. I have done this and it works fine, the problem comes when a person does a half day i.e. 7:30 - 11:30, this will read 4.5 hours. If this is the case I don't want the 30mins deducted so it should be 4.0 hours worked. I have high lighted a column in the work sheet (yellow) whereby the user puts an 'x' in the appropriate cell if they are working a half day. The probem is I cannot incorperate the two formulas in one cell (the Actual hours cell) I have the one formula in the actual hours cell and the other bolted on the end thus giving two different readings.

Formula To Give A Time Minus 15 Mins
i have =TIME(LEFT(F17,FIND("h",F17)-1),RIGHT(F17,2),0). which gives a time in the format 9:30PM, or 10:30AM etc. How would i change the formula to give me a time minus 15 mins. Eg, if the above formula gave me 8:45PM, i would want it to show 8:30PM

Calculate Hours Worked, Minus Weekends
to calculate how long a ticket is open in our system before being resolved. I don't want to count weekends, and if the ticket is 'suspended', I don't want to count that either. There is also the factor that the ticket 'un-suspend' date may be later than the ticket 'closed' date. Which is the bit that's throwing me.

So, I have the following fields

Ticket Open, Ticket Closed, Ticket Suspended Date, Ticket Unsuspended Date

A sample ticket might be (using above fields)

02/11/09 09/11/09 04/11/09 30/11/09

That 'should' equal two days (16 hours) as the Unsuspend date falls after the close date so it was suspended from the 4th until closure.

Now I want to know, in hours (8 hour day) how long that ticket took to resolve (i.e close), remembering you can't count the time it was suspended, or any time that fell over a weekend. Also not all tickets are suspended.

Formula Change Seconds To Hours And Mins
Formula that will change seconds to hours and mins, example 270 mins would show up as 4 hours 30 mins, not 4.5 hours. My second thing is how can I double the times in the same formula.

Difference Between Dates And Times In Days , Hours Mins ( Working Hours )
The below formulae allows me to see the difference between two dates and only returns the difference in working hours ie :
Difference between
02/02/2010 08:00 & 03/02/2010 08:00 is 16 Hours 0 Minutes

=(INT(A3)-INT(C6))+MAX(MOD(A3,1)-MAX(MOD(C6,1)))

The following displays it in the Hrs and Mins format

=TEXT(B15,"[h]")&" Hour"&IF(OR(TEXT(B15,"[h]")+0=0,TEXT(B15,"[h]")+0>1),"s "," ")&MINUTE(B15)&" Minute"&IF(MINUTE(B15)1,"s ",""))

i need to convert second to Hours and mins and can do so using:

Countif Of Hours And Mins Not Dates
I have a data feed that gives a column of cells formated mm/dd/yy hh:mm
These are call entries, what i want to do is count all the occurances each hour, so count all the entries say between 9am and 10am. However the column is very long and holds data for many weeks so i want to be able to ignore the date part of the cell.

For example

3/17/09 9:58
3/18/09 10:58
3/18/09 8:58
3/19/09 8:58
3/19/09 9:58
3/19/09 9:58

So the entries between 9 and 10 are = 3

Ideally i do not want to do text to colums and split out the parts. i would like to leave the source data alone.

Nested IF Command: Calculate Today's Date Minus
The range B7:K7 contains columns of "dates" and "characters" like "A", "B" and "C" . Range D2 = Today's date. If Range C7 is blank then it should calculate Today's date minus Column B7 (i.e D2-B7) so on:

B7 = "01-Apr-2009", C7 = "02-Apr-2009", D=7 = Status as "(A)"
B7 = Submitted Date, C7 = Received Date, D7 = Status
Difference Between Today's Date and "B7" date is required if "C7" is Blank date. Otherwise it should search next group (E, F)

=IF(AND(ISBLANK(C7),NOT(ISBLANK(B7))),D2-B7,IF(AND(ISBLANK(F7),NOT(ISBLANK(E7))),D2-E7,IF(AND(ISBLANK(I7),NOT(ISBLANK(H7))),D2-H7,IF(AND(ISBLANK(L7),NOT(ISBLANK(K7))),D2-K7,"--")))))

I can use Sheet Two for the next part, but I don't know how to to get a total time per month for each seperate jeep. Most of the time, there will only be one record per month per jeep, like the second line above. But lines one and three are for the same jeep, and so I need the formula to add column E up only for those two lines.

Rules 3:The starting time may fall After 5 PM, then we have to do calculation from 9 AM on the next day. (Let's say start date with time 17/04/07 8:00:00 PM, then we have to consider the date with time from 18/04/07 9:00:00 AM for the calculation)

Rules 4: It has to exclude the Saturday and Sunday

Calculate Date/time Format Over 24 Hours
I need to calculate the difference between two cells that are formated like this: 11/10/2006 13:00. Simple subtract only works when the date hasn't changed (the subtract formula seems to focus on the time and ignore the date).

I found a formula that will work, but the results are in regular numbers, I need the hh:mm format and if I change the format of the result column, the time displayed is wrong.

The formula is=((B2-A2)*1440)/60)

If my result is 122.6 in regular numbers, when I convert to hh:mm I get 14:00.

Is there a better way to do this? Also, is there a way to eliminate weekend & holiday hours from the calculation? This is not as important as getting the results to calculate correctly in the hh:mm format.

Calculate Hours Worked After Specific Time
i have a timesheet that we are trying to use. the problem is the column that says shift diff. if an employee works after 6:30pm for 1and 1/2hr, he is entitled to shift hours. shift hours is between 6m and 8am.

As long as he works after 6.30pm but works for at least one and a half hour, he will get the shift.

if work, 9am to 7:30pm, and have break between 2-3pm, should have 1.5hrs shift and 9.5hrs total
if work, 7:45pm-9:45pm, and have break between 8:30-9pm, total hrs work is 1.5 and shift hrs s/b 1.5hrs
if work 3pm to 12am and have break between 7-8pm, total hrs work is 8 and shift hrs s/b 5hrs

Example:
First slot is from 08:00am till 17:00pm, time cost 100%
Second slot is from 1700am till 24:00, time cost 110%
Third slot is from 24:00 till 08:00 am, time cost 120%

I'm working from 08:00am till next day 01:00am
So my hours are:
9 in slot 1,
7 in slot 2,
1 in slot 3.

Is this possible to calculate in Excel?

Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates.
