In the book of Nehemiah (chapter 8), we find a description of an ancient Rosh HaShanah at the time of rebuilding Israel after a period of exile.
The blessing after the reading of haftarah always sanctifies the day on which it is read. Throughout most of the year, that day is Shabbat, but haftarahis also read on the High Holidays. On Rosh HaShanah and Yom Kippur the text changes from the familiar Shabbat text to refer to the holiday.
Every morning I wake up at 5:30. Rolling over, I grab my computer and check Twitter, Tumblr, my blog, and make sure I remembered to do all my homework.
