It will help to familiarize oneself of the "Order of Precedence" from the General Norms for the Liturgical Year. This is usually found at the preliminary pages of official liturgical books such as the Liturgy of the Hours and the Roman Missal. These table will help you determine if a Solemnity or Feast occurring on the same day outranks the other. Then you pray the one with a higher rank. For example: Solemnities of the Blessed Virgin Mary outranks Sundays in Ordinary Time, therefore LH and Mass of the Solemnity of the BVM is celebrated instead of Sunday OT. That is so, the Solemnity of the Assumption, August 15 (Rank 3rd) if falling on a Sunday is celebrated instead of the Sunday OT (Rank 6th). Liturgists call this Occurrence and Concurrence. Hopefully this helps further especially for beginners. To make it easier if your particular diocese or conference of bishops issues an ORDO or Liturgical Calendar for the year - get a copy - it saves time figuring it out.
During Lent, Memorials may still be celebrated in a reduced manner. Wherein the prayer of the saint is added after the prescribed prayer before conclusion.
