How these dates are calculated
Every date on this page is computed from planetary positions for each day, not copied from another site or estimated. The same ephemeris generates our daily horoscopes and birth charts. Positions are geocentric and tropical, and dates are given in UTC — a transit can land a day either side in your local time zone.
Last calculated 18 August 2026.
