Make a custom time format in Excel - excel

How can I create a custom time format?
I'm using a Excel sheet to track my work hours. And I add up the work hours for each day and get a week total. But it seems it cant display above 24:00. unless I change the format to hh:mm:ss.
I don't want the extra 2 digits at the end but the only other option is hh:mm.#
I want it to be hh:mm but display more than 24 hrs (like 36:50).
I also don't understand the "custom" option can someone help?

Use:
[hh]:mm
As your custom format

Formatting Existing Excel Cells to Time Format Without Date

I'm working on an excel 2010 sheet where I mark down the date and time an event happens. The date is in one column, and auto formats to 17-Nov when I would type in 11-17 (I was fine with this). The time is in a separate column.
I am trying to find the average time an event occurred, without regard to the date, so I would use =AVERAGE(C1:C10). However, I only receive a date back (like 17-APR).
I did not format the cells before I began to enter in data, and I would simply type in a 3:27pm event as 1527, and no reformatting would happen.
Now, when I attempt to reformat the column to hhmm, all the numbers entered so far turn to 0000. When I try to edit the 0000, it is formatted as 6/13/1906 12:00:00 AM.
What I want to do is have the time formatted as hhmm and not include a date in the cell, and be able to run formulas on it, such as the average time an even occurred.
Summary:
*Currently time is entered simply as ####. I entered 3:27pm as 1527.
*Trying to reformat the time column results in 0000 in all cells in the column that previously had a ####.
*Modifying the 0000 displays as 6/13/1906 12:00:00 AM
*I want to format the time as hhmm so I can simply type in 2357, and have it display as 2357, but understand I mean 11:57pm, and let me take averages.
*Hell, even being able to enter 1547 and have it auto format to 15:47 or 3:47p would be great.
Thanks for reading my question!
An easy way to apply an autoformat (though Excel won't see it as a true "Time") is to go into Format Cells>Custom> and use ##":"##. This will turn 1245 into 12:45. Mind you, this will be a text string so if you copy it to another cell and then apply a time, it will show as 12:00:00. Excel will also not be able to run formulas on it, but it's a quick and dirty way to make it look pretty.
Another option is to have a formula such as =TIME(LEFT(A1,2),RIGHT(A1,2),) where A1 would be replaced with the cell you are actually referencing. This will convert the number to a time that Excel will recognize as a time allowing you to run other functions on it, but requires another column.
If you are entering the times as 4-digit numbers, you'll need to do a calculation to get the hours and minutes, then use the TIME function to get an actual time:-
=TIME(A1/100,MOD(A1,100),0)
Another way is
=LEFT(A1,2)/24+RIGHT(A1,2)/1440
but then you have to format the result as a time.
Excel sees a number like 1547 as approximately 4 years on from 1st January 1900 if you format it as a date, so it will come out as something like 26/3/1904 in UK format or 3/26/1904 in US-style format.
Note that the time function can only give you values up to 23:59:59 (stored as 0.999988426), but the second method will give you a datetime value with one or more days as the whole number part. This can be useful if you want to do calculations on times spanning more than one day.
The above behaviour is because dates and times are stored as real numbers with the whole number part representing days and the decimal part representing fractions of a day (i.e. times). In spite of misleading information from Microsoft here, dates actually start from 31/12/1899 (written as 0/1/1900) with serial number 0 and increment by 1 per day from then on.

Convert mm'ss'' to mm:ss in excel

How I can convert a register of time of for example 28'30'' to 28:30 in excel?
I have tried to change the formatting in custom but it doesn't work. There is any formula to change it?
Thanks!
To get it as a time in minutes and seconds (if it was originally a string in A2):-
=TIMEVALUE("0:"&SUBSTITUTE(SUBSTITUTE(A2,"'",":"),"""",""))
and then format cell as time.
=LEFT(A1,2)&":"&MID(A1,4,2)
for text-to-text conversion.

Excel - Date Time Format ; If time is PM add a day

In excel I currently have data in date time format
For example: "11/10/2007 8:40:58 PM"
I am trying to extract the date and if the time is PM, I add a day.
if the time is AM, the date remains the same.
So since the time is 8:40:58 PM I would want 12/10/2007.
Is there a way in excel to do such a thing using formulas?
Please consider using the following formula. This uses the fact that in Excel in its date-time code uses 1 to represent a full day and fractions to represent the time. If timestamp is in A1 then:
=INT(A1)+IF((A1-INT(A1))>=0.5,1,0)
Regards.
This one works for me.
=IF(A1>0.5, A1+1, A1)
In order to have it only return the date right click on column B, select "Format" the take your pick.

summing time excel spreadsheet not working

I have a issue with excel, I am trying to add up time so they can be displayed correctly in the spreadsheet that I am making, I have requests from user and give them how long it will take to change or fix. on the sheet I am displaying 01:00:00 which means the time taken is 1 hour, and displaying the sum usinfg =sum(A1:A10) which adds up fine when the time is under 24 hours, but if the sum is grater is show up as 03:00:00, i would like to know if it is possible to show time as 27:00:00 which means 27 hours the change will take. not three how would i allow this to be displayed
youu need to use the following custom cell format : [hh]:mm:ss

How to create and assign a Custom Format of date and time to an entire column in excel worksheet

I want a customized format(with milliseconds also) in such a way to handle for a date and time in Microsoft Excel.
Sample date and time:
08.25.2010 00:52:09.359
For understanding of above sample date time, it is 25th August 2010 12 hrs 52mins 9seconds 359 milliseconds(AM).
Please provide a custom Format to handle the above mentioned sample date and time and finally to apply for a column.
In Excel 2003 I use the following for time with fractions of second:
"hh:mm:ss,000"
(note: my decimal point is a "," - German)
so a time entered as 12:13:14,1516 will be displayed as 12:13:14,152
Hope this works for you
Edit 28-Nov-2012
I recently migrated to Excel 2010. Special format using up to 3 zero's after a comma for seconds as described above still works. More than 3 zero's however are not accepted.
I'm not certain what you mean by "not recognizing the dates" but the following custom format would give you the format you're looking for. You'll have to adjust the millisecond separator "." according to your localization, of course.
mm.dd.yyyy hh:mm:ss.000
Applying it to a column is as easy as right clicking the column header, selecting Format Cells, choosing Custom on the left and pasting that format string into the Type box.
If you're trying to enter dates in this format, I don't believe that Excel will support that. I don't know of any option to set the date separators to a "." for Excel. Even setting the date format to use dots under the Regional and Language Options doesn't make Excel recognize that.
