Well, in Western Christianity there were/are the Rogation Days[1] and Ember Days[2] (and extra-liturgical customs that could vary from place to place), certainly related to "making sense of the world" with respect to cycles of nature. Holy Week (preceding Easter) and Easter itself are full of themes and symbolism, but the focus is different — it's square on the mysteries of the Passion, Death, and Resurrection of Jesus Christ. See for example the Exsultet[3] and the Victimae paschali laudes[4] [1] https://en.wikipedia.org/wiki/Rogation_days https://en.wikipedia.org/wiki/Rogation_days [2] https://en.wikipedia.org/wiki/Ember_days https://en.wikipedia.org/wiki/Ember_days [3] https://en.wikipedia.org/wiki/Exsultet https://en.wikipedia.org/wiki/Exsultet [4] https://en.wikipedia.org/wiki/Victimae_paschali_laudes https://en.wikipedia.org/wiki/Victimae_paschali_laudes
