Javascript fot the sunrise and the sunset

[Eurydice]

For a given town I search a javascript that gives the hour of the sunset and
the sunrise.
Looks simple but not found up to now on the net

Thanks

No, it's nothing close to simple.
That's meteorological data that changes daily and would not be quite the same
over years. If you actually had all that data in a database, you'd still need
a server-side script to retrieve it (not client-side javascript).

I'd look into a web service from a national agency that keeps track of these
things or some other provider. My guess is that's where such data would
normally come from (i.e. Excite.com's section that has such data). I would
not attempt to keep such data in a DB myself unless the towns I kept track of
numbered less than 10. Even then I'd probably go find it somewhere else.
That'd be hell to keep updated.

For example:

Can't help you with the "placename to longitude and latitude" conversion
but you could convert Roger Sinnotts 'cheap and cheerful', 'tried and
tested' Sunup.bas to javascript yourself <URL:
http://skyandtelescope .com/resources/software/programs/sunup.bas> (info:
<URL: http://skyandtelescope .com/resources/software/article_326_1.a sp>)
or I can dig out an old conversion I did myself that I have archived
away.

Try this from Steve P. Morse:

The javascripts are:
city-us.js
city-ca.js
city-xx.js
sunrise.js

Has this become the obsession of some
demented French DHTML tutor?

A fellow Frenchman seems interested in the same script.
...Oh wait, that was you. Why did you repost?
