Calculating Rest Times Over 2 Days

[MOTORBIKEBITZ]

I need to calculate my rest time between work,

I finish work say at 19:32:00 on one day and start again at 08:18:00 the next day or maybe 2 day later

How do I work out my rest period ? only need hours and min, seconds not needed

Thanks in advance

Will the date be stored in the same cell as the time, or in a separate cell?

Will you please attach a SMALL sample Excel workbook (10-20 rows of data is usually enough)? However, please give us an indication of the approximate number of rows of data you want the solution to work with (100, 1000, 100,000 or whatever). Please don't attach a picture of an Excel sheet (no-one will want to re-type all your stuff before starting).

1. It does NOT have to be your real sheet - mock up a SAMPLE if you need to. But not 1000's of rows!!! It makes manual checking so tedious. Whatever you do... make sure that all confidential information is removed first!!

2. Make sure that your sample data are truly REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

3. Make sure that your desired solution is also shown (mock up the results manually).

4. Try to avoid using merged cells. They cause lots of problems!

Unfortunately the attachment icon doesn't work at the moment. So, to attach an Excel file you have to do the following: Just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Hi, i think think is working ? file called time, I have put explanations instead of formulas

Your sample differs from Post 1. In Post 1 you stated that there could be several rest days. In your sample, every day had some entries. This works with your sample, but possibly not with your real data.

=IF(B5="","",MOD(B5-D3,1))

in H5, copied down.

That seems to work, thank you very much, can you explain how it works, hate not knowing

[Glenn Kennedy]

It simply subtracts the two times (which Excel thinks of as numbers). If the time period crosses midnight a negative number is returned. So end (06:00) - start (20:00) = 0.25-0.916666 = -0.66666. MOD retursn the remainder following division by 1 = 0.66666. Excel divides that by 24 (hrs in a day) to return 8 hrs. Your answer.

If the time period does not cross midnight: end (14:00) - start(06:00) = 0.58333 - 0.25 = 0.3333. The remainder, following division by 1 is still 0.3333 = 8 hrs.

You're welcome.
