Why this exists

I wanted a simple way to compare a handful of time zones at a glance, and to relate them back to whatever time it is where I am. No ads, no sign-up, no tracking.

Conversions come from your own device's time zone database, so daylight saving is always current. Sunrise, sunset and the sky colours are computed from each city's latitude and longitude rather than fetched, and the page caches itself, so it keeps working with no connection. MIT licensed.
