Religious Acceptance Worldwide

  Religious institutions in general seemed to be more reluctant
  to take to the new system.

  German Protestants used the old calendar until 1776, three
  quarters of a century after their countries had adopted the

  Gregorian system.

  Sweden retained the old Easter rules for 90 years after
  switching to the Gregorian calendar, and many Middle

  Eastern Christian sects still retain the Julian calendar.

  The Russian Orthodox Church still follows the Julian system.
