Tx Andrew, makes my day.<div><br><div>As a hobby Haskell user I&#39;d be very happy to see more packages with real-world algorithm for plain application usage, e.g. </div><div>- tuple with sunrise, sunset, twilight times for a given day, lat, lon</div>
<div>- distance calculations (haversine etc.)</div><div>- other geo/bio/time/loc/3D-alg... </div><div><br clear="all">-- Markus<br><br>

Is there any Haskell package/impl already that calculates sunrise and sunset<br>
for a given location (via lat/lon)?<br>

I have some code which does this.  However, it should really be integrated<br>
with existing packages, such as Data.Time.Calendar.  I&#39;ll email it to you<br>
off-list, but I&#39;m just letting everyone know in case someone wants to<br>
own it.<br>
