Christians across the globe have come together to celebrate Easter. Easter Sunday falls on the same day in 2017 in both the eastern and western churches. This is the first time it has happened since 2014, and it will not happen again until 2025, since Orthodox Christianity is based on the Julian calendar, while the religious festivals of western Christianity are based on the Gregorian calendar.
