Vernal Equinox 2025 Uk. Unlike most christian celebrations, easter's date is dependent on the moon and lunar cycles. On this day the sun will illuminate the northern and southern hemispheres equally, and day and night will be roughly the same length.
The equinox in the northern hemisphere occurs twice a year around 20 march (the spring equinox) and around 22 september (the autumn equinox). Read about vernal equinox around the world in 2025.
