RedLetter a calendar where the days that matter are printed in red

Sky calendar, 2027

Equinoxes, solstices and cross-quarter days are exact instants, shown here in UTC. They are moments rather than days, so which calendar date one falls on depends on your timezone. Meteor shower peaks are nights, and fall on the same local date almost everywhere. Eclipses are listed with the region they can be seen from: a total solar eclipse is total only along a narrow track, so the date alone does not tell you whether you will see anything.

How these are calculated

Equinoxes, solstices and cross-quarter days come from Meeus, Astronomical Algorithms (2nd ed.), including the periodic corrections and ΔT, accurate to well under a minute rather than the fixed calendar dates most listings repeat. Meteor shower peaks are the long-term averages published by the International Meteor Organization: a shower is a night of activity, not an instant, and the exact hour of maximum shifts from year to year. Eclipse dates, types and visibility regions come from NASA/GSFC's eclipse catalogues (Fred Espenak), which are in the public domain.
