Original: The Yamim Noraim are preceded by the month of Elul , during which Jews are supposed to begin a self-examination and repentance , a process that culminates in the ten days of the Yamim Noraim known as beginning with Rosh Hashanah and ending with the holiday of Yom Kippur .
Simplified: Rosh Hashanah is the first of the High Holidays or Yamim Noraim , or Asseret Yemei Teshuva ( The Ten Days of Repentance ) which are days specifically set aside to focus on repentance that conclude with the holiday of Yom Kippur .
