Good going Dave, it does work. I hope the times it gives are correct!
Kidding!
Also, I am sure you can add a line of code to read the date on one's own computer everytime that applet loads, therefore defaulting to that person's date. A handy technique to just simply going to your applet on the web, and if already defaulted to that date (for both date options given), simply click 'Calculate', and voilá - you have that days/nights time(s).

Then how about a picture representation?See I knew this place is awash with great ideas.

Here is another idea,
How about io/europa/ganymede/callisto transit times along with shadow transit times, now that would make it even more useful.

Hi Dave,
I've tested it in Firefox 3 and it worked fine.
I found the passwords a bit difficult to read tho' (maybe I need my glasses changed).

Good, its not just me who thought that! Or perhaps I'll see you in specsavers!
Looks good DG, any plans to share the code or even the algorithms used? I'd be pretty interested in seeing whats involved in the calculation.
Cheers,

Cool, I can find out if I'll ever be able to see the red spot through the 5 minute gap in the trees next door.
Now I just need a calculator to find out what times Jupiter is in the gap every night and then compare results to find a match
On a serious note, is this calc not a bit moot for the next 2 or 3 years for us here though. Will we be able to see/image the GRS with 15-20 deg altitude seeing anyway or will this calc come into its own in about 2011 for us.

While you are at it Dave, can you write one for transits of the ISS across the disc of the Moon and Sun as visible from Ireland? Should be a *simple* task for someone like yourself.
