Just found this (http://www.schoolsobservatory.org.uk/cgi-bin/srs_uk.cgi) , quite useful so I thought I'd share the link.

Very handy - I was trying to find something like this earlier to know if I could use the bikes for my daughters Judo club (no lights).;)

Just dont forget that from a flying point of view irs really official day/ night that really matters.

Official day = 30 mins before sunrise
Official night = 30 mins after sunset

Useful for my 'new' car too ... the panel light switch doesn't work. :O I did think about wearing a head torch while driving. :D

I've used this link at the US Naval Observatory (http://aa.usno.navy.mil/data/docs/RS_OneYear.html) before, which I then imported into Excel and tidied up the formatting. Very useful - enables you to prepare a full year of data for your location of interest.

We used to have a copy of this in the Duty Instructors Log at the Air Cadet VGS where I used to assist, also put a copy of it in the aircraft log book at Perth (based on Perth Lat / Long).
