Yes; this applies to calculations for Easter using either the Gregorian and Julian calendars. But, it does not apply to Julian calendar dates converted to Gregorian calendar dates. In many Western Christian denominations that use the Gregorian calendar, for example, Easter can fall as early as March 22 and as late as April 25. It has fallen on April 1 a few times, the last being in 1956. It will occur again on that date in 2018. According to the Julian calendar, the last Orthodox Easter on April 1, for example, was in 1996. The next will be in 2058. However, when these dates are converted to the Gregorian calendar, Orthodox Easter falls on April 14 for these years. Note that when converted to Gregorian calendar dates from the Julian calendar dates, Orthodox Easter can not fall earlier than April 3.
