Last week over at the Chandoo.org Forums, Birko asked a question about How to Import some Numbers as Times.
“I have imported some data that comes in as a number that I need to convert to h:mm. The data string will be either 1,3,4,5,6 integers long and looks like this…eg
Imported Need to equal this
Number h:mm
0 0:00
100 0:01
1000 0:10
10900 1:09
235900 23:59
Can someone please provide a smart formula to convert this (assume data is in cell A1).”
Today in Formula Forensics we will look at how this problem was solved, and the solution which may surprise you.
Importing Numbers as Times.
When I first saw this data I start by looking at patterns.
Working backwards through the list
I can see that 235900 is 23 Hrs, 59 Min and 0 second
I can see that 10900 is 1 Hr, 9 Min and 0 second
I can see that 1000 is 0 Hrs, 10 Min and 0 second
I can see that 100 is 0 Hr, 1 Min and 0 second
I can see that 0 is 0 Hr, 0 Min and 0 second
I then start to think about how to extract the Hours, Minutes and seconds independently from the Text using a series of Left, Right and Mid functions, and quickly realised that due to the varying lengths of the strings, That they will end up being complex formulas as I will need to allow for each string length.
What if I pad the strings with leading 0’s and then extract them.
That is possible, but as a single formula it will be long and cumbersome as the padding has to occur a number of times for each Hour, Minute and Second as part of the Time() function.
So padding may work but is cumbersome, then a bright light moment
What about I use the Text function to do the padding.
And I quickly posted the following formula:
=(LEFT(TEXT(A1,"000000"),2)/24)+(MID(TEXT(A1,"000000"),3,2)/1440)+(RIGHT(TEXT(A1,"000000"),2)/(24*3600))As Time is just a number between 0 = midnight and 0.999999 = 11:59:59 pm, I can extract the Hours, Minutes and seconds separately and then simply add them together to get the actual time
I Can use the Text function to display the Strings in a consistent format that allows me to use the Left, Mid and Right functions to retrieve the Hours minutes and Seconds from the appropriate places.
Lets work through this formula section by section and see what is going on.
Hours
The Hours component of the formula is
=(LEFT(TEXT(A1,"000000"),2)/24)+(MID(TEXT(A1,"000000"),3,2)/1440)+(RIGHT(TEXT(A1,"000000"),2)/(24*3600))
=(LEFT(TEXT(A1,"000000"),2)/24)
Working from the middle out, this formula takes the value in A1 and displays it as a Number with the format “000000”
So using our data
235900 will convert to 235900
10900 will convert to 010900
1000 will convert to 001000
We can now use a Left() function to extract the hours from the first 2 characters of the converted string
Using our examples:
Left(235900,2) = 23
Left(010900,2) = 01
Left(001000,2) = 00
To convert hours to a Time we simply divide by 24
Minutes
The Minutes component of the formula is
=(LEFT(TEXT(A1,"000000"),2)/24)+(MID(TEXT(A1,"000000"),3,2)/1440)+(RIGHT(TEXT(A1,"000000"),2)/(24*3600))
=MID(TEXT(A1,"000000"),3,2)/1440
Once again, Working from the middle out, this formula takes the value in A1 and displays it as a Number with the format “000000”
So using our data
235900 will convert to 235900
10900 will convert to 010900
1000 will convert to 001000
We can now use a Mid() function to extract the minutes from the middle 2 characters of the converted string
Mid(235900,3,2) = 59
Mid(010900,2) = 09
Mid(001000,2) = 10
To convert Minutes to a Time we simply divide by 1440 (1440 is how many minutes are in a day = 24 * 60)
Seconds
The Seconds component of the formula is
=(LEFT(TEXT(A1,"000000"),2)/24)+(MID(TEXT(A1,"000000"),3,2)/1440)+(RIGHT(TEXT(A1,"000000"),2)/(24*3600))
=RIGHT(TEXT(A1,"000000"),2)/(24*3600))Once again, Working from the middle out, this formula takes the value in A1 and displays it as a Number with the format “000000”
So using our data
235900 will convert to 235900
10900 will convert to 010900
1000 will convert to 001000
We can now use a Right() function to extract the minutes from the middle 2 characters of the converted string
Right(235900,3,2) = 00
Right(010900,2) = 00
Right(001000,2) = 00
To convert Seconds to a Time we simply divide by 86400 (86,400 is how many seconds are in a day = 24 * 60 * 60)
Total Time
To get the total Time we simply add the Hour, Minutes and Seconds together
=(LEFT(TEXT(A1,"000000"),2)/24)+(MID(TEXT(A1,"000000"),3,2)/1440)+(RIGHT(TEXT(A1,"000000"),2)/(24*3600))

35 Responses to “Skip weekends while autofilling dates in excel”
[...] Original post by Chandoo [...]
Hi,
Is there any way that I will choose which are my "working days"?
means, I want to leave also Friday as a free day and not only Saturday.
Or, maybe someday I will pick Tuesday as a day off.
I need to also peek Wednessday, Thursday and Friday as days off. Also, for Tuesday, I would need to leave it off once every two weeks. Is there a way to easy achieve this, so that I won't actually add to my workload?
Hi Mihai... you can use pattern fill feature to do this. Simply follow steps in below demo.
Hi,
I am using MS Office 2007 and for some reason, it does not show me these options. It just shows me 3 options:
Copy Cell (Not sure about the exact text)
Copy with Formatting
Copy without Formatting
Any idea how to get those options up?
Regards,
Deep
@Deep : I am not so well versed with 2007, but here is how you can do this using menus:
enter first date of the series
select the range you want to fill
go to menu > edit > fill > series
in the dialog, select date as the series type and "weekdays only" option
press ok...
Let me know if this doesnt work...
Now that was FAST!!!
I tried it but unfortunately it didn't work..
Here is the screenshot:
http://img291.imageshack.us/img291/6573/excelsheetyr2.gif
This is what I tried..
I put the date in one row, in another row, added some calculations (as you can see in the image) and drag the content in other rows..
I could not find any Edit menu so i just clicked on the icon as you have shown in the 2nd image..
I hope I did the right thing...
Hmm...
there should be an edit menu as far as I know. Let me check that...
meanwhile... if it works you can use formulas to fill the series.
1. just enter the first date
2. in the 2nd row, enter a formula like =if(weekday(firstdatecell,2)=6,firstdatecell+2, firstdatecell+1)
3. copy the formula over the rest of the range...
@Deep:
you have to use the autofill handle, the small box at the lower right of the active cell. Right click on the autofill handle and drag down to the cells you want to autofill. A menu pops up showing the weekdays only option and others.
@Chandoo - Thanks but it did not work with my calculations. 🙁
@Robert - Yes, it worked this time but I guess, in my case it won't work as I want to add up the days from the column on the left. (As shown in the image)
Basically this is what I want:
1. I want to define project start date
2. There are no. of days assigned for each module
3. I want excel to calculate the date automatically. (By adding up the no. of days and deducting the weekends)
Any kind of help is appriciated.
Reagrds,
Deep
@Deep,
sorry, I misunderstood your question, I thought you would be searching for the autofill-function only (values).
If I got your request corrctly now, you could use the WORKDAY-function, returning the date before or after a specified number of workdays.
In Excel 2003 and earlier the Add-In Analysis Toolpak has to be installed, but since you are using 2007, it should work immediately.
@Deep.. as Robert suggested, Workday is what you should be using. It will calculate future date based number of working days you want to add to input date. Also, you can use this with your own list of holidays.
Thanks Robert, Chandoo.. I will try the things.. 🙂
I tried it and this time it worked.. Thanks to both of you.. you guys made my life much more easier 🙂
[...] You can also customize excel lists so that you can auto-fill, lets say bank holidays in your country or types of beer in your pub. One more auto fill trick. [...]
Hello,
I understand how to turn off the weekend values for a date fill in a regular auto fill. But, what if you are trying to create a custom one, that counts the amount of days in the formula bar, like 2 days, then 5 days, then 1 day etc etc etc, but they must be working days only and they must not include the weekends.
can that be done?
thanks!
hi..
i'm using excel 2007
I'm trying to insert current date automatically
then it suppose not to change after i save and open it on the next day.I need it to stay on the issued date.
i'm using Today function and it is not well work 4 me.
anybody can help to resolve my prob here?
please...
Hi guys,
How about if I just wanna fill up with weekend? The way I am doing now is using the function weekday and use filter to get weekend. Would appreciate if any one comes up with a better idea. Thank you very much.
Regards
Cheng
What happened to being able to indicate the series by adding a few cells and then using the autofill to copy? I can't get this to work - I need 4 rows with the same date skipping weekends.

Hi Kathy, sorry for a late comment. However, here's the solution.
1.) put your 1st desired date in the 1st 4 cells required (e.g. <cell A1:A4> 2/6/2012)
2.) put the following formula as is in the following four cell (i.e. A5:A8)
=IF(WEEKDAY(A1,2)=5,A1+3, A1+1)
=IF(WEEKDAY(A2,2)=5,A2+3, A1+1)
=IF(WEEKDAY(A2,2)=5,A2+3, A1+1)
=IF(WEEKDAY(A2,2)=5,A2+3, A1+1)
Note: "=5" denotes the number of working days in the week
"+3" denotes the number of days on weekends.
"+1" last denotes the number of days after the working date.
3.) Finally, select cells A4:A8 and then drag drown for furthur dates. The formula will skip Saturday & Sunday in the dates.
Let me know, if you want to tweak the formula as per other ways.
Kamlesh: Thanks for the formula. That was what I was looking for. It works the same in Google Docs Spreadsheets. At first I thought it didn't and did some unnecessary tweaking to make it work.
I was confused by the "IF(WEEKDAY(A2,2)" the modifier 2. I took it out and surpise, the formula didn't work right. I changed the 5 to 6 and then it worked. Turns out, (you probably know this) the default week starts with Sunday. Using 2 makes it start with Monday.
Any way, I didn't know about the Weekday function. Thanks for sharing this post.
Hi, Kamlesh, before i was using "workday" instead of "weekday" but it didn't work.
thanks for sharing the right formula.
At this moment I am going to do my breakfast, when having my breakfast
coming yet again to read further news.
Hi,
I'm using excel 2007
I'm trying to calculate a workday
4 nov 2014(a1) to 12 nov 2014(a2)
Normally i'm using Int formula to do this
=int(a2)-int(a1)
But, hey thats including weekend too... 😀
how do you calculate workday with this condition ?
and if there is not only those day, i mean in a month or two
Thanks before
sagari
@Sagari
=NETWORKDAYS.INTL(DATE(2014,11,4),DATE(2014,11,12),1)
=7
You can also include holidays into the formula by having a list of holidays in say A1:A10
Then use
=NETWORKDAYS.INTL(DATE(2014,11,4),DATE(2014,11,12),1,A1:A10)
Thanks for replying
Get #NAME? in return when using NETWORKDAYS.INTL
But get 7 with NETWORKDAYS
why ??
Hi
i had a query while making a template for one of my school daily task.
Most of the work in these template includes copy from webpage and paste in the template.
so the problem here is, whenevr me or my mates try to do ctrl+v
the format of the cell changes automatically.
I suggested them to use ctrl+alt+v (text) to paste
but they are not ok with it. they want me to make template in such a way that it should work with normal ctrl +v
Any ideas guys ?
Our working week is Tuesday to Saturday if I wish to make a sheet solely using those days is there a formula I can use ?
I need your support for date.
I wand to numbering actual working date based on date
below is expected result... so how can apply formula to get number automatically... please help me get resolve this problem... many thanks in advanced.

Dear Sir,
I want to make a series of December month which will show all the dates without Fridays.
Is it Possible sir??
Interesting question Salauddin... The built-in options in Excel can't generate dates like this. But you can use simple formulas to make up such a series.
In first cell (say A1) write the starting date (1-Dec-2019 for example). Makesure this date is not a Friday.
In the next cell (A2) write =WORKDAY.INTL(A1,1,16)
Now drag down the A2 cell to fill up dates. Stop when you reach the end of your range of dates.
If your Excel doesn't have WORKDAY.INTL(), then use the below alternative formula.
=A1+1+(WEEKDAY(A1)=5)
Thank you, Thank you very much sir. it worked perfectly & I was expecting something like that.
i want to make a template with date that skips fortnightly is it possible in excel
Hi Chandoo, I need to skip weekends from a specified list of dates.
from the below information I want to pick only the weekdays amount only along with lookup which has builder name separately.

Thank you! I've been struggling with this for ages and today, thanks to this post, I finally figured that I had to customize my toolbar in order to utilise the "Fill" menu. This will make my monthly reports much, much neater
