During Birkat Kohanim you can see the Kohanim put their "talleisim" over their heads every day of the year.
Factoid: Brikat Kohanim is the Priestly Blessing performed on a daily basis in the land of Israel. In the diaspora the ceremony is performed only on Pesach, Shavuot, Sukkot, Shemini Atzeret, Rosh Hashanah, and Yom Kippur.
