Tzitzit blessing

Hello Rabbi, I wanted to ask in what instances would a person need to bless on putting on the tzitzit throughout the day? If, for example, one changes his tzitzit for a diffrent one (a new one in honor of Shabbat) would one need to bless on the second one? Someone taking a nap during the day would need to bless while putting on his tzitzit again? Thank you very much for your answer.

Shalom!

Thank you for your question.

First of all, let me just share with you that as a general rule, when in doubt, a blessing is not recited. There can only be more harm than good when one recites a blessing when one shouldn’t, so one should be knowledgeable of the Halachot and not just assume.

A blessing is not recited on a Tallit that was removed for a short time, such as when a Tallit is taken off for a short time to leave the synagogue and then return. This is true even if it has been half an hour or longer since it was taken off. So too, one who goes to the bathroom does not make a new blessing when putting the Tallit back on upon exiting the bathroom.

Same too if one removed his Tzitzit when taking a nap, if it was a short nap, one doesn't need to recite again a bracha, if, however, one sleeps from the morning till the afternoon, then one has to recite another bracha.

One who removes a Tallit with the intention not to put it back on will be required to recite a blessing when it is eventually put back on.

One who removes one’s Tallit in order to put on another Tallit and then changes one's mind will be required to recite a new blessing on the original Tallit since there was "hesech hadaat" - ("one's mind has been diverted").

One who puts on a second Tallit/Tzitzit garment will recite a blessing if one did not have the second garment in mind when the first one was put on, (in a case he did have it in mind when reciting the bracha then he does not have to recite a new bracha as long as he was not mesi'ach da'at).

Therefore, this would answer your second question with regard to putting on the Shabbos tzitzit, you would have to recite a new bracha when putting it on, unless you had it in mind when you recited the bracha in the morning, and you were not mesi'ach da'at.

One who folds up and puts away one’s Tallit in its bag will be required to recite a blessing when/if it is put on again. This is because the act of folding and putting away the Tallit is a declaration that one has concluded the mitzva, and indeed, it has ended. Hence, when “re-starting” the mitzva a new blessing will be required. However, one who put his Tallit away by mistake thinking it was no longer needed, and then realizes it is still needed, such as for Mussaf on Rosh Chodesh,  may re-wear the tallit without a blessing.

The general rule is that questions/answers on when to recite a blessing on a Tallit are similar to questions/answers on when to recite a blessing on food.
