@jkcheney @edebill currently sunrise 6:15, sunset 6:10 in Barentsburg so pretty close to exactly 12 actually!

The issue with the equinoxes is that for certain astronomical things (eg figuring out equinoxes) the sun is treated as a single center point, but for many practical considerations thats not the relevant definition — so sunsets are typically calculated by the trailing edge and sunrises by the leading (if you can see the sun at all, it counts as up). And then you often get a period of dusk (when you can’t see the sun but there’s still light shining up past the horizon) before true night, making the nights seem even shorter than they are — astronomical twilight doesn’t end until the sun is a full 18° below the horizon
