Calculating hours online

I don’t usually ask technical (ie, boring) questions like this here, but I’m going to now.

I would like to be able to calculate hours, such as from a time card. In other words, I want to be able to enter:
5:15 am - 4:25 pm
9:55 pm - 12:54 am
and get back 14h 9m.

This is a simple calculation, and there are all sorts of web pages to calculate just about everything for you, but I can’t find one that will do this. Does anyone know of one? Would anyone like to design one?

I don’t know of a calculator better or more simple than the mind.

If you want to calculate your time on line, ask your service provider. At least mine will e-mail you your hours in the last month just by requesting it.

Thanks a lot, bare. Why didn’t I think of adding up times from dozens of days in my head? :rolleyes:

I have done that, but it is very tedious and time consuming, and I don’t trust myself not to have made a mistake.

And BTW, I’m not trying to calculate my hours on line. I’m trying to calculate the hours I’ve worked over the past month so I can bill my employer accurately.

I wrote something like this for a client. Since she never paid for it, you’re welcome to it. Here’s the link. You may have to alter the JavaScript a little to make it do what you want.

Thanks, Baraqiyal. That’s pretty close to what I want. I don’t know JavaScript, so I can’t “improve” it, but I think it’ll be helpful anyway.

how about using a spreadsheet? That’s what I’d use

Using Microsoft Excel you can determine the number of days, hours, and minutes it will take for Bill Gates to conquer the Universe. Simply subtract the times/dates and format the solution cell as a number not a date.
