From September 1, 2023, the Ukrainian Greek-Catholic Church in Ukraine will switch to a new style for immovable holidays while preserving the current Easter. This was stated by the Father and Head of the UGCC His Beatitude Sviatoslav on the live broadcast of "Live TV", announcing the decision of the Synod of Bishops of the UGCC in Ukraine regarding the calendar reform.

 "Taking into account the numerous requests of the faithful and having conducted preliminary consultations with the clergy and monastics of our Church regarding the urgent need to reform the Liturgical Calendar of the UGCC in Ukraine, as well as taking into account pastoral considerations:

 A. The UGCC in Ukraine will switch from September 1, according to the new style (beginning of the Indictus) of the year of God 2023, to a new style for non-moving holidays with the preservation of the current Easter.

 B. For those parishes or individual communities that feel they are not yet ready for such a step (with the special blessing of the diocesan bishop), to leave the possibility of liturgical life according to the Julian calendar for the period until the year of God 2025," says the 5th resolution of 93- and session of the Synod of Bishops of the UGCC in Ukraine, which took place on February 1-2, 2023 in Lviv-Bryukhovychy.

 In Ukraine, Christian churches follow two calendars: Gregorian (Roman Catholic Church) and Julian (Greek Catholic and Orthodox Churches).

 There is also the New Julian calendar, which practically does not differ from the Gregorian calendar.
