I want sum of all duration entries in x hours x minutes x seconds like i have more then 1000 rows of duration when i try to use =SUM(C2:C100) I am not getting sum of total duration after sum of 24:00:00 24 hours it starts from 00:00:00
for example sum of total duration gets 24:00:00 between range of c1:c8 it will start from 00:00:00 from c9: next range kindly assist me how to overcome this issue

try:
=ARRAYFORMULA(TEXT(SUM(IFERROR(TIMEVALUE(C:C))), "[h]:mm:ss"))

Wherever you put the =SUM(), Select that cell and do Format>Number>More Formats>Custom Number formatting, and put the same formatting that Player0 put in his answer:

What worked for me to resolve a similar problem was a suggestion by user ttarchala in Google Sheets Query multi condition sum of time duration.
I used N() function as he said, and my final formula for the duration is:
=IF(To<>"", N(To-From+(To<From))*24, "")
with To and From being Named ranges for End Time and Start Time respectively.
N() function converts the time delta into a number. Multiplied by 24, this gives the hours in decimal format, such as 2 hours 30 minutes = 2.5 hours.
From there on, there is no problem with using the built-in Sum function to calculate the total duration as a decimal. Such as, the total duration of 27 hrs 10 minutes is shown as 27.16. This sufficed for my purposes.
Time delta is calculated using a formula from https://webapps.stackexchange.com/questions/104829/calculate-time-difference-between-times-past-midnight to take into account past-midnight differences.
And the first condition, To<>"", makes sure the formula is not showing in empty cells. As soon as the End Time is filled into "To" column, the decimal duration is calculated. Then it can be used in the regular Sum function.
This seemed shorter and easier than the formulas suggested above so I am sharing it in the hopes it may help someone else. Using thus formula, I just added up the Sum of time I spent looking for this solution: 3.34 hours :)

It's a formatting problem. You formatted your reply as HH:MM:SS, therefore the number displayed is not showing the date, which would have been incremented by one. If you multiply your sum by 24, and then format the result as a pure number, you will get a number that goes above 24, and will show you the number of hours, and its decimals. If you use those hours in further calculations, the result will be correct.

In cell C1, use the formula
=IF((B1-A1)>=0, B1-A1, 1+B1-A1)
Explanation: the problem is durations that exceed the 24 hour limit, as you say.
Google Sheets has become a bit deceptive here, as it will show the correct duration for the individual time interval, but if you SUM over it, it will actually deduct the value!
A B C
23:39 1:10 1:31
When you SUM then Google Sheets will see the value in cell C1 as if it was the beginning of the same day as the time in A1. So when you in C1 do =B1-A1 then it will register as a negative duration! But it won't show up as that!
In C1 use this formula, =IF((B1-A1)>=0, B1-A1, 1+B1-A1) for individual cells in column C, when you see that cells in column B has exceeded the 24-hour limit once. The duration in C1 should still show 1:31, but now the result when doing SUM over a range of cells in column C, like =SUM(C1:C2), will now show the correct and strictly additive sum. You can safely copy this formula to all cells in column C.
PS: cells in all of the columns can have Automatic or no formatting (which I think defaults to Automatic), if your time inputs look like the above. So you don't need to format all of those cells to Time or Duration. BUT remember to format the SUM cell to Format -> Number -> Duration.
PPS: if you are manually inputting the times (for for instance time tracking), then the easiest way to keep the much simpler =B1-A1 formula is to split the time up into two rows, like this:
A B C
23:39 0:00 0:21
0:00 1:10 1:10
Then the SUM of cells in column C still becomes 1:31.

Time function in sheets

I have the data of 4000 employees in google sheets along with their shift timings (9 hour long shift) spread across 24 hours. I wish to use a formula to understand the most common timing these employees are available in the office (09:00 to 18:00). My results would be 09:00 to 11:00, 11:00 to 13:00, 13:00 to 15:00, 15:00 to 18:00, 18:00 to 22:00, 22:00 to 09:00.
I could have used this formula to derive to the value:
=IF(AND(TIMEVALUE(A2)>=TIMEVALUE("09:00"), TIMEVALUE(A2)<=TIMEVALUE("11:00")), "09:00 to 11:00",
IF(AND(TIMEVALUE(A2)>=TIMEVALUE("11:00"), TIMEVALUE(A2)<=TIMEVALUE("13:00")), "11:00 to 13:00",
IF(AND(TIMEVALUE(A2)>=TIMEVALUE("13:00"), TIMEVALUE(A2)<=TIMEVALUE("15:00")), "13:00 to 15:00",
IF(AND(TIMEVALUE(A2)>=TIMEVALUE("15:00"), TIMEVALUE(A2)<=TIMEVALUE("18:00")), "15:00 to 18:00",
IF(AND(TIMEVALUE(A2)>=TIMEVALUE("18:00"), TIMEVALUE(A2)<=TIMEVALUE("22:00")), "18:00 to 22:00", "22:00 to 09:00")))))
but the problem is the timings are not in the time format but they are in text format
Here's my take:
Suppose Column A has clock ins, and Column B has clock outs. Let Column D have Times starting at 00:00 and going up to 33:00 (8am next day) in 5 minute (or 30, 60 etc) increments.
Let column E be the amount of clock in and outs that an employee was in the office at the time referred to in E.
We will define E to be =COUNTIFS($A$2:$A$9999,"<="&D2,$B$2:$B$9999,">="&D2).
Next, apply some conditional formatting to highlight the most busy times.
Note that you will need only the times of day, which it sounds like you have, but you will need to convert overnight shifts to not wrap around midnight.

In Google Sheets, how do I multiply a duration or interval constant? [duplicate]

Original close reason(s) were not resolved
I'm making calculations on production cost (in number of resources) and duration.
I have a process that takes 5 minutes. Using the Duration format, I would enter that as 00:05:00.
I want to queue up this process a certain number of times and calculate the total duration. The output should either be something like 16:35:00 or 5 02:15:00. A "d HH.mm.ss" format.
How, in Google Sheets, do I multiply a Duration by an integer to get a total Duration? To be clear, I am not doing a summation of a column of durations. I am taking a duration constant, such as 5 minutes or 25 minutes, and multiplying it by an integer representing the number of times the process will be run, consecutively.
All these attempts resulted in Formula Parse Error:
=(5*00:05:00)
=(112*00:05:00.000)
=(VALUE(C27)*00:05:00)
=MULTIPLY(VALUE(C27),00:05:00.000)
Well, blow me down. I came up with a workaround while I was trying different ways to fail. I assigned 00:05:00 to it's own cell with the Duration format, then referenced that cell in the formula.
I.E. =C27*J7 gives me 9:20:00 when C27 equates to 112 (it's a summation of it's own) and J7 is the cell holding 00:05:00.
Still doesn't give me days when it goes over 24 hours, and I'd rather have the duration value as a constant in the formula, but it's a step forward.
Would something like this work for you?? It's no longer a number, but if it's for expressing the amount in your desired format it may be useful:
=IF(ROUNDDOWN(W2*W3),ROUNDDOWN(W2*W3)&"d "&TEXT(W2*W3-ROUNDDOWN(W2*W3),"hh:mm:ss"),TEXT(W2*W3,"hh:mm:ss"))
Change the cell references, obviously
PS: If you want to have the value as a constant in your formula, you can try to change the cell reference with TIME function within your formula:
In both Excel and Google spreadsheet, DATE are represented in a number start counting from 1899/12/30,
which...
1 is equal to 1 day
1/24 is equal to 1 hour
1/24/60 is equal to 1 minute
1/24/60/60 is equal to 1 second
you can do like:
=TODAY()+1 which gives you tomorrow, or...
=TODAY()+12/24 which gives you "date of today" 12:00:00
and when you are done with the calculations, you can simply use a TEXT() to format the NUMBER back into DATE format, such as:
=TEXT(TODAY()+7 +13/24 +15/24/60,"yyyy-mm-dd hh:mm:ss")
will return the date of a week away from today at 01:15:00 p.m.
This date/time format doesn't requires a full date to work, you can get difference of two time format like this:
=TEXT(1/24/60 - 1/24/60/60,"hh:mm:ss")
since 1/24/60 is 1 min, and 1/24/60/60 is 1 second,
this formula returns 00:00:59, telling you that there is a 59 seconds diff. between 1 min and 1 sec.

Doing hourly rate calculations for hour more than 24

I am recording my time spent on a project in google excel sheet. There is a column which does addition of the recorded time and output total time to column say D40. The output time looks like <hoursspent>:<minutesspent>:<secondsspend>. For example 30:30:50 would mean that i have worked for 30 hours and 30 minutes and 50 seconds on a project.
Now, I was using this formula to calculate my total invoice
=(C41*HOUR(D40))+(C41*((Minute(D40)/60)))+(C41*((SECOND(D40)/3600)))
Where C41 cell contains my hourly rate (say $50).
This is working fine as long as the numbers of hours that i have worked are less than 24. The moment my numer of hours go above 24. The Hour function return the modulus value i.e., HOUR(30) would return 6.
How can I make this calculation generic in a way that it oculd calculate on more than 24 hours value too.
Try
=C41*D40*24
and change formet on the result as $
one hour is part of a day, as you know 1/24th of a day, that's why you could multiply by 24 to get hours, and then multiply it by the rate
Try below formula-
=SUMPRODUCT(SPLIT(D40,":"),{C41,C41/60,C41/3600})
When you store a value as HH:mm:ss into an Excel sheet, it automatically formats it as a Time, so it makes sense that HOUR modulos by 24.
Which is why you can simply ignore it. If you have a cell that is formatted as currency (FORMAT > Math > Currency) or any other normal Number-like format, then you can see, if you perform a numerical operation like multiplication, that it stores times like "30:30:50" as if it were a TIMEVALUE with a value over 1. Simply multiply that by 24, and then by your hourly rate, and you'll get your value, i.e,
=D40 * C41 * 24 :
Just replace HOUR(D40) with INT(D40)*24+HOUR(D40)

Highlight Duplicate Within 24 hours timestamp but a different date

I am trying to figure if the following can be done. If there are duplicate names in the B column then it will see if the date and time were within 24 hours of each other in the A column, if so it will highlight the cell yellow.
Currently, the formula I have will only highlight if it was on the same date. Is there a way I can add to the formula to all take into account time? So that if one response is on 5/20/20 at 17:00 and the next duplicate name is at 5/21/20 at 16:00 then the cell would be highlighted.
Here is the formula I am using the just highlights if it is within the same date:
=ARRAYFORMULA(COUNTIFS(B:B, B2, DATEVALUE(A:A), DATEVALUE(A2))>1)
I am not sure if something like this is possible. I am guessing that the formula would have to compare both datevalue and timevalue. Any help would be appreciated.
Instead of DATEVALUE you can use TO_PURE_NUMBER
This will return you the number of days from January 1, 1900 including the fraction for past hours and minutes opposed to DATEVALUE that rounds the value down to an integral day number.
Sample:
This allows you to calculate the real difference time between your timestamp.
For example like this:
=ARRAYFORMULA(or(COUNTIFS(B:B, B2, TO_PURE_NUMBER(A:A), ">"&TO_PURE_NUMBER(A2)-1, TO_PURE_NUMBER(A:A), "<"&TO_PURE_NUMBER(A2))>0,COUNTIFS(B:B, B2, TO_PURE_NUMBER(A:A), "<"&TO_PURE_NUMBER(A2)+1,TO_PURE_NUMBER(A:A), ">"&TO_PURE_NUMBER(A2))>0))

Auto incremented day

I need to fill column with date incremented by one day for the whole year. How to make it in automatic way?
UPD:
I have 2017-06-12 in B60
If I add 24 hrs I still have previous day. Why?
=B60+time(24,0,0)
If I add 23 hrs - day increase works.
=B60+time(23,0,0)
if
The reason why
=B60+TIME(24,0,0)
doesn't work is that times between 00:00:00 and 23:59:59 are stored as values between 0 and (nearly) 1. The maximum value that you can get from the TIME function is =TIME(23,59,59) - if you put =TIME(24,0,0) then it rolls back to 00:00:00 which is stored as zero. If you add zero to anything (including a date) you just get the original value.
You need to put in the value for a day which is just 1 so the formula should be
=B60+1
See Time Function Documentation
Just drag down the first cell.
A1 = start date:
5/29/2017
A2 = number of days:
365
A4 = formula:
=ARRAYFORMULA(ROW(INDIRECT("a1:a"&A2))+A1)
From here and here:
Put in A1 the value 30/12/2012 08:15:00
Put in A2 the formula: =A1+time(23;59;59)
Copy the formula in A2 down as far as you need.
