English: Timeline of the main Old Calendarists and True Orthodox Greek Orthodox Churches.
All those churches are called "True Orthodox Church (of Greece)" or "Greek True Orthodox Church", either officially or colloquially, whether they practise True Orthodoxy or not.
True Orthodox: churches which either consider themselves True Orthodox (the ideology), or which considers New Calendarists/churches practising ecumenism as graceless, or both. Old Calendarists: those who only refuse the new calendar. All True Orthodox are Old Calendarists, but not all Old Calendarists are True Orthodox. In case of doubt concerning the position of a church, it is assumed the church kept the ideology of the church it left.
The date for the Matthewite schism vary between 1936 and 1937 according to which source you look at. The date for the GOC-Avlona schism is either 2007 or 2010 according to which source you look at.
