When Was Neptune Last in Leo?
Updated October 5, 2026
As of October 2026, the last time was 1914–29: Neptune first entered Leo on 23 September 1914 and, because retrograde motion carried it back and forth across the sign's boundary, entered it four times in all before leaving for good on 24 July 1929. Next: Neptune first enters Leo on 1 September 2078; retrograde motion carries it back and forth across the sign's boundary, so it enters three times in all and leaves for good on 5 July 2093.
Each bar runs from first entry to final exit. Stretches marked with a neighbouring sign are times it crossed back over the boundary before returning.
Every Neptune-in-Leo pass, 1600–2600
Dates are in UTC and the Gregorian calendar; in a time zone far from Greenwich an ingress can fall on the neighbouring calendar day. Dates before 14 September 1752 are Gregorian too, though Britain and its colonies still used the Julian calendar, 10 days behind until 11 March 1700 and 11 days behind after, and began the year on 25 March.
