Some myths say that for one third of the year Persephone stays with Hades, and for two thirds of it with her mother.
Persephone usually spends half of the year on Earth (spring and summer) before returning to the underworld for the other half (fall and winter). This cycle is tied to the changing of the seasons in Greek mythology.
In Greek mythology, Persephone spends half of the year on Earth with her mother, Demeter, and the other half in the underworld with her husband, Hades. This cycle represents the changing seasons: spring and summer when Persephone is on Earth, and fall and winter when she is in the underworld.
Every year, Persephone spends the autumn/winter (when plants die) with Hades, and returns with spring/summer.
Persephone stays in the Underworld for half of the year (six months) and is allowed to return to Olympus for the other half.
Persephone was born in a meadow on Earth
Persephone is a Goddess of the Earth, and the Goddess of the Underworld.
Demeter and Persephone were both goddesses of the earth. Gaia (Earth) through her daughter Rhea, who was the mother of Demeter and grandmother of Persephone.
On Earth and Olympus, Persephone is the Goddess of Spring.
Well in the story of Demeter and Persephone Persephone has to stay in the underworld for 6 months so when Persephone is on earth it is warm and things grow and harvest but when Persephone is in the underworld nothing grows and it is cold
Persephone ate of the pomegranate in the Underworld and thus had to stay in the Underworld for part of each year - during winder she was with Hades; during spring, summer and autumn she resided above the earth with her mother Demeter.
Persephone and Hades are still married.
To either go back to the earth with her mother Demeter, or stay in the Underworld with her husband Hades. This was resolved by Zeus into half year stays with each.
