**Please Note: **
This article is written for users of the following Microsoft Excel versions: 2007 and 2010. If you are using an earlier version (Excel 2003 or earlier), *this tip may not work for you*. For a version of this tip written specifically for earlier versions of Excel, click here: Counting Times within a Range.

William has a list of times in column A. He needs a way to find how many of the times fall within a time range, such as between 8:30 am and 9:00 am. He tried using COUNTIF and a few other functions, but couldn't get the formulas to work right.

There are actually a few different ways you can count the times within the desired range, including using the COUNTIF function. In fact, here are two different ways you could construct the formula using COUNTIF:

=COUNTIF(A1:A100,">="&TIME(8,30,0))-COUNTIF(A1:A100,">"&TIME(9,0,0)) =COUNTIF(A1:A100,">=08:30")-COUNTIF(A1:A100,">09:00")

Either one will work fine; they only differ in how the starting and ending times for the range are specified. The key to the formulas is to grab a count of the times that are greater than the earliest boundary of the range and then subtract from that the times that are greater than the upper boundary.

You can shorten the formula by using the COUNTIFS function instead:

=COUNTIFS(A1:A100,">=8:30",A1:A100,"<=9:00")

You could also use the SUMPRODUCT function to get the desired result, in this manner:

=SUMPRODUCT(--(A1:A100>=8.5/24) * --(A1:A100<=9/24))

This approach only works if the values in the range A1:A100 contain only time values. If there are dates stored in the cells as well, then it may not work because of the way that Excel stores dates internally. If the range does include dates, then you need to modify the formula to take that into account:

=SUMPRODUCT(--(ROUND(MOD(A1:A100,1),10)>=8.5/24) * --(ROUND(MOD(A1:A100,1),10)<=9/24))

Finally, you could skip formulas altogether and use Excel's filtering capabilities. Apply a custom filter and you can specify that you only want times within the range you need. These are then displayed and you can easily count the results.

Alex - The formula refers to 8:00 as start. The 9 o'clock start should be 0.375, 3/8 of 24hrs.

Rob

try something like this

Date OpenHour Close Open Formulas in M

01/3/2017 11:00 23:30 12:30 =L2-K2

Mgr1 10:30 14:00 3:30 =L3-K3

Mgr2 17:30 24:00:00 6:30 =L4-K4

Supervised 10:00 =SUM(M3:M4)

% Supervised 80.00% =M5/M2

Hope you can make sense, pity we can't insert a graphic.

Alex, any of the formulas should do the trick unless the time have been imported and include a date (select one and look in the formula bar to see if there is a date included in the value.

If there is use something like this to find the count between 9AM and 5PM

=SUM(IF((E4:E33-INT(E4:E33))>=0.3333,1,0))-SUM(IF((E4:E33-INT(E4:E33))>=0.70833,1,0))

This is an array formula that must be entered with Ctrl + Shift + Enter. Excel places a curly bracket round the formula.

How about finding times within a certain hour window?

For example: I am checking that the time of data collected and the time the test was conducted falls within an 8 hour window.

Help in this will be greatly appreciated

I have managers working in a restaurant between 7am and 11:30pm and would like to know the percentage of time that I have a manager scheduled.

=SUMPRODUCT(--(ROUND(MOD(A1:A100,1),10)>=8.5/24) * --(ROUND(MOD(A1:A100,1),10)<=9/24))

this formula works on one worksheet but not another. Any idea why?

thx

what if i want track certain activity(specific text ) timely range

Thanks for the tips on using countifs. I am trying to calculate an elapsed time from two date/times using specific time criteria. i.e., a patient comes in on 1/16/16 17:29 and leaves on 1/18/16. This patient would require a person to sit with them, and the typical sitter hours are either 6a-6p or 6p-6a. How would I get a count of how many sitters were needed for that specific time period per patient using the start & stop time? Any ideas appreciated. Thanks.

That SUMPRODUCT equation for the dates worked like a charm! You saved me countless hours of research and work in a crunch! I truly appreciate it!

This was insanely helpful! I had been banging my head against the wall, almost literally, for the past few days trying to get this to work. Thanks so much for putting this out there.

Thanks for the great and helpful formula! Question: what format do the times in the cells need to be in? i.e. text, number, time, custom, etc.?

Thank you!

Hi Team, i need to generate a automated production tracking excel for my team. i had workout on some areas, right now am looking for making work easier in excel. i have created a column named status of the job ex. processing, completed waiting for query lunch break etc. now i need it to be auto mated. while selecting the processing status the time should be start in a separate cell. as well as the rest of the status menu.. so that my team member no need to enter the time manually for every action.. they just need to select the options when they selecting the dropdown the timing should start in a different cells.. is it possible how i need to work it

When using this formula, =SUMPRODUCT(--(ROUND(MOD(A1:A100,1),10)>=8.5/24) * --(ROUND(MOD(A1:A100,1),10)<=9/24))

How would I input midnight? 00:00 - 00:59

Hi,

I have an events list with a start column and an finish date column. I would like to do a search or filter for all events starting on a certain date please. So if there is a start date of say 1 Jan 14 and finish date of 12 Dec 14, I would like to do search or sort for events starting on 1 Jun 14 and the above example would be displayed because it is in the time period.

Any advisce on this would be gratefully received as I have been racking my brains to find a way to do this.

Many thanks

Dear All team.

i need a time range formula,we open your site and search a time range formula and we found and apply this =COUNTIF(A1:A100,">=08:30")-COUNTIF(A1:A100,">09:00")

such a good and better for me

thanks for all team

There are times when you need to have dynamic input and creating parsing routines within built-in functions can be a pain creating long function strings. So you create a new macro or function ...

Function CountTimes(TimeData As Range, FromTime As Date, ToTime As Date) As Long

Dim Counter As Long

Dim CellData As Range

Counter = 0

For Each CellData In TimeData

If CellData >= FromTime And CellData <= ToTime Then Counter = Counter + 1

Next CellData

CountTimes = Counter

End Function

This will count anytime blocks of data using standard time input values.

Michael Avidan is correct. But while I hesitate to disagree with an MVP, I'd like to offer the view that including the double-minus signs is a useful safeguard as it covers the instances where you may either forget about this quirk of Excel or where you can't be bothered to work out whether it will bite you or not.

I agree it's a weird looking usage and the first time I saw it I had to go off googling to find out why it was used. But it does seem to be a useful trick.

Including it is a bit like including default values explicitly - just helps to make assumptions visible.

As I mentioned before there was indeed no need for the "Double Minus signs".

There are some cases where the formula: (B10=E10:E15)

returns somethig like: {TRUE;TRUE;FALSE;FALSE;TRUE;FALSE}

Such a result cannot be summed - therefor the "Double minuses" covert it into:

{1;1;0;0;1;0} which can, easily, be summed.

*** The result of the first minus is all negative values:

{-1;-1;0;0;-1;0}

and the second Minus makes it all to be Positive.

Sometimes, you can use the function: N - which does the similar conversion to the TRUE/FALSE.

=--(B10=E10:E15) equals: =N(B10=E10:E15)

I like Juan’s question and have seen other symbols in formulas and wonder why they are there and what they do. Is there a reference on how to use them.

What do double minus sins mean in SUMPRODUCT?

2012-12-29 17:22:07

Bob Davey

If using the filter option add the subtotal function if the volume of results returned is too great to quickly count manually.

You could do the whole lot with a simple macro and an input box for the required values and return the result/s with a msgbox

2012-12-29 10:11:43

Michael Avidan - MVP

No need for the "Double Minus sins" because True * True = 1 and True * False = 0.

Therefor:

=SUMPRODUCT((A1:A100>=8.5/24)*(A1:A100<=9/24))

is more than enough.

If the amount of data is not too large, you van user the function Interval.

You can also use a pivottable if the amount of data is very large. A pivottable gives you the possibility to group a certain range of times and dates.
