Catholic News Service (CNS), the official news service of the United States Conference of Catholic Bishops (USCCB) just posted the following Tweet:
This is #LaudatoSi Week. May 24 is the fifth anniversary of Laudato Si, #PopeFrancis encyclical on “our common home.” Here’s a special prayer for the anniversary. pic.twitter.com/hZ81DuonTX

Funny, we don’t recall CNS publishing annual observations for other papal encyclicals like Humane Vitae and Veritatis Splendor.
