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.
