The longest void this month begins on December 23 at 23:54 and ends on December 25 at 01:09, when the Moon enters Pisces; 25h 15m in total. The Moon enters this void at 16°39′ of Aquarius, having completed a sextile to Mercury. The shortest period lasts 15m.
Classical electional astrology advises against starting new work, signing contracts or sending important proposals during these hours; the concern is not misfortune but inconsequence. Routine tasks, rest and ongoing business are unaffected.
Calculated by the classical method: the five major aspects the Moon forms with the Sun, Mercury, Venus, Mars, Jupiter and Saturn; outer planets are not counted. The void begins when the last aspect becomes exact. For the whole year see the 2025 calendar, and for live calculation the Void of Course Moon calendar.
