Sky calendars for 2027
These pages list the dated events of 2027 that astrology talks about most. They cover retrogrades, eclipses, moon phases and the days the Sun changes sign. Each date is worked out here from planet positions, not copied from another list. Every time is written in UTC and in the time zone of your device.
What the calendars cover
In 2027 there are 17 planet stations and 10 retrograde periods, some of which begin before the year or end after it. There are 5 eclipses, 12 full moons among 49 moon phases, and 12 days when the Sun changes sign. Each page below lists one of these in full.

How the times are written
Every time is a minute, and the UTC column comes first because UTC is the same everywhere. The "Your time" column is filled by your browser from the time zone it reports, so the same event can fall on a different calendar date for you than it does in UTC. Each page can also make a calendar file on your device.
How the dates were checked
The positions come from the same calculation as Live Sky. For 2027 they were compared with the tables of the U.S. Naval Observatory, which round to the minute, and with JPL Horizons. The largest difference was 40 seconds against the Observatory and 25 seconds against JPL Horizons. Eclipses were checked against the catalogs of the Goddard Space Flight Center. The methodology page lists each comparison.
The dates and times on these pages are calculated by AstroJane and compared with published tables; the methodology page lists each comparison and its limit.
