  Good Friday is the Friday before Easter, which is calculated differently in Eastern Christianity and Western Christianity (see Computus for details). Easter falls on the first Sunday following the Paschal Full Moon, the full moon on or after 21 March, taken to be the date of the vernal equinox. The Western calculation uses the Gregorian calendar, while the Eastern calculation uses the Julian calendar, whose 21 March now corresponds to the Gregorian calendar's 3 April. The calculations for identifying the date of the full moon also differ.
  
  In Eastern Christianity, Easter can fall between 22 March and 25 April on Julian Calendar (thus between 4 April and 8 May in terms of the Gregorian calendar, during the period 1900 and 2099), so Good Friday can fall between 20 March and 23 April, inclusive (or between 2 April and 6 May in terms of the Gregorian calendar).
