In the previous halacha we mentioned the times for davening Shacharis. With regard to the section of davening called Pesukei DeZimra, one is allowed to start that section of davening from alois hashachar, the break of dawn, and Pesukei DeZimra may be said all the way until chatzois, midday. One is allowed to say Birchos Kriyas Shema, the Brochos of Shema, until the end of the fourth halachic hour. The Tzemach Tzedek and other poskim allow the saying of Birchos Kriyas Shema all the way until midday. (There are even poskim who permit saying them throughout the day until shkiya, sunset.) The morning Shema can be said anytime from misheyakir, a time when one can recognize a friend, until three halachic hours in the day have passed. Both of these times are usually noted in the calendar. If one didn't recite Shema at its proper time in the morning, it may be said until shkia, but then the time for reciting Shema will have passed and it would only count as Torah study. As mentioned in the previous halacha, the latest one could daven Shemonei Esrei is midday, the halachic time of chatzos.
