A Daylight Chart for Sydney
23rd February 2010

Alright I'm here doing something I told myself I wouldn't, that is double post (you would have noticed this if you subscribe to my Github RSS feed). But I feel that I have a wider audience here than on my Github RSS feed.

Anyway I recently put together a daylight chart using some existing tools. You can see it here. Here is the static image version (the one in the link is drawn with JavaScript and has some interactivity). This is for 2010 in Sydney in Sydney's timezone.

Chart showing sunrise and sunset times for Sydney (Civil Twilight and the other common measurement of sunrise and sunset are shown).

PS. I don't know what those jumps in March are, look into the DateTime::Event::Sunrise perl module for the answer.
