The following is an animated image of the liturgical year 2016-2017 according to the Roman Catholic rite. It's called "liturgical year" or "Christian Year" at the time ranging from the first Sunday of Advent and the last week in Ordinary Time during which the Church celebrates the whole mystery of Christ from his birth to his second coming. One can say that the liturgical year consists of two times: strong times and ordinary time. The strong times are, Advent, Christmas, Lent and Easter, during which a particular mystery of salvation is celebrated. Ordinary Time, in turn, does not hold any particular mistery, but rather the same mystery of Christ in its fullness, especially on Sundays. Ordinary Time is divided into two parts throughout the liturgicaL year and in total lasts 33 or 34 weeks. Note that in the image below the corresponding date of 2017-07-01 has been highlighted.
