formula to sum hours if

[KGIL789]

Hello all!

I have a spreadsheet at work that the techs enter in on/off times for equipment. I need to know how many hours the equipment has ran that day.

Date	Initals		OFF ALL DAY?	ON ALL DAY?	INITIAL SHUT DOWN	INITIAL START UP	SECONDARY SHUT DOWN	SECONDARY START UP
5/1/2019	BB				11:00	18:30
5/2/2019	BB			YES

<tbody>
</tbody>

Data such as the above. All times are put in using a 24hr clock. The on/off all day columns are drop down lists for YES or NO.

Is there a formula such that I can put in 0 hrs if YES off all day, 24 hrs if YES on all day, and then if neither of those are true, calculates the hours operated that day? I've tried a couple versions and it doesn't seem to pull through correctly for all cells. I don't think I was nesting the IF statements correctly. What I was using for everything excluding IFs was requiring additional columns that stated start of day was 0:00 and end of day was 23:59, and taking all the columns subtracted from another and * 24. IE this formula: =((J327-I327)+(L327-K327)+(N327-M327))*24


Appreciate the help!

Hi, below should work for you:

=IF(E2 <> "Yes",IF(D2 <> "Yes",24*(1-G2-I2+F2+H2),0),24)

I think the columns were a bit off. Is this correct?

Book1
	B	C	D	E	F	G	H	I	J
1	Date	Initials	All Off	All On	Init Shut	Init Start	Sec Shut	Sec Start	TOTAL
2	5/1/2019	BB			11:00	18:30	19:00	20:00	8.5
3	5/2/2019	BB		YES					24
4	5/3/2019	XX	YES						0
5	5/4/2019	AA			9:00	13:00			4

There is a spacer column between initials & All Off - there's actually 5 pieces of equipment here, so one date column for all 5, and a spacer column between each equipment piece. There's about 20 people that enter data into this spreadsheet, so it's an easy visual break for where they need to be entering in data.

The formula worked!!! Thank you so much! I think I was way, way overthinking it.

For background - this all used to be handwritten & hand calculated.....which is a heck of a lot of time spent doing this. Thanks again!

There's only one so far that seems off - I have an initial shutdown of 23:30 (no other numbers given) which should return a time on of 23.5, and it's showing 47.5.

In my formula, if Initial shutdown is 23:30 and there is no initial start-up, it shows -23.5. (can you "shut down" without a "start-up"?)

Yes - the equipment was already running from the previous day. So for that day, it should be treated as though start up was 0:00, but in reality the equipment was started up four days ago.
