Discussion was lengthy because although Serbia officially supported the political calendar, Milanković (an astronomical delegate to the synod representing the Kingdom of Serbs, Croats and Slovenes) pressed for the adoption of his own version, in which the centennial leap years would be those giving remainder 200 or 600 when divided by 900 and the equinox would generally fall on 20 March (as in the Gregorian). Under the official proposal the equinox would sometimes fall on 22 March. This might make Easter fall outside its canonical limits due to the requirement that the Easter full moon follow the equinox. Also his scheme maximised the time during which the political calendar and the Gregorian would run in tandem.
