After the Divine Office, many mark the day through the recitation of the Angelus. Now that we have entered Eastertide (Easter to Pentecost) we pray the Regina Caeli (To be more precise, it is prayed from Holy Saturday through Eastertide). It is most common to recite it at noon but also very appropriate at 6am and 6pm.
The author of the Regina Caeli is unknown but has been used since the twelfth century. Wikipedia (no comments) shares that,
It was in Franciscan use, after Compline, in the first half of the following century. Legend has it that St Gregory the Great heard angels chanting the first three lines one Easter morning in Rome, while following barefoot in a great religious procession the icon of the Virgin painted by Luke the Evangelist. He was thereupon inspired to add the fourth line.
This is a beautiful tradition to mark time throughout our day.
