Liturgy of the Hours - Các Giờ Kinh Phụng Vụ

In case you need it (ICYNI). I used to pray along the Liturgy of the Hours (Divine Office or Breviary) at DivineOffice.org for my own meditation and peace. Now, it opens for new members during this pandemic as detail here:

(You don't need to fill out all information, just email and name that enough)

On Sunday, I pray along in Vietnamese using https://ktcgkpv.org/readings/prayer

According to US Conference of Catholic Bishops (USCCB)
http://www.usccb.org/prayer-and-worship/liturgy-of-the-hours/index.cfm :

The Liturgy of the Hours, also known as the Divine Office or the Work of God (Opus Dei), is the daily prayer of the Church, marking the hours of each day and sanctifying the day with prayer.

Another web site I like it too. No registration need it.
