How your sky is made

Your local birth time is converted to universal time with the full history of your time zone, including daylight saving rules that have since changed. Stars come from the Yale Bright Star Catalogue; the Sun, Moon and planets are calculated with published astronomical methods for 1800 to 2050 and checked against worked examples. All of it runs in your browser.
