The Vernal Equinox
The Easter Date is calculated as the first Sunday after the full moon following the vernal equinox. The vernal equinox occurs at a certain time on either March 20th or 21st when the center of sun is vertically over the equator and on that day, night and day are roughly of the same length of time. The "First day of Spring" falls on the same day as the vernal equinox. This means that Easter always occurs in the Spring and typically following the first full moon. Sometimes it follows the second full moon [see 2019 in the chart].
