The earliest time for tallit and tzitzit

Hi,

There is an "earliest time" for the mitzvah of donning tzitzit or a tallit; before that time, one who puts on tzitzit or a tallit does not recite a blessing on them. Many calculate this time as 45 or 60 minutes before sunrise.

One who puts on tzitzit or tallit before the "earliest time" should wait until the earliest time arrives, then recite the blessing, then shift the tzitzit/tallit around somewhat and re-settle them in place.

(Shulchan Aruch Orach Chaim 8:16; Mishneh Berurah 8:43)

Have a great day,
Mordechai
