<P> All of these are believed to be Canaanite names . These names are only mentioned in connection with the building of the First Temple . Håkan Ulfgard suggests that the use of what are rarely used Canaanite (or in the case of Ethanim perhaps Northwest - semitic) names indicates that "the author is consciously utilizing an archaizing terminology, thus giving the impression of an ancient story ...". </P> <P> In a regular (kesidran) year, Marcheshvan has 29 days and Kislev has 30 days . However, because of the Rosh Hashanah postponement rules (see below) Kislev may lose a day to have 29 days, and the year is called a short (chaser) year, or Marcheshvan may acquire an additional day to have 30 days, and the year is called a full (maleh) year . The calendar rules have been designed to ensure that Rosh Hashanah does not fall on a Sunday, Wednesday or Friday . This is to ensure that Yom Kippur does not directly precede or follow Shabbat, which would create practical difficulties, and that Hoshana Rabbah is not on a Shabbat, in which case certain ceremonies would be lost for a year . Hebrew names and romanized transliteration may somewhat differ, as they do for Marcheshvan / Cheshvan (חשוון ‎) or Kislev (כסלו ‎): the Hebrew words shown here are those commonly indicated, for example, in newspapers . </P> <Table> Hebrew names of the months with their Babylonian analogs <Tr> <Th> #</Th> <Th> Hebrew </Th> <Th> Tiberian </Th> <Th> Academy </Th> <Th> Common / Other </Th> <Th> Length </Th> <Th> Babylonian analog </Th> <Th> Holidays / Notable days </Th> <Th> Notes </Th> </Tr> <Tr> <Td> </Td> <Td> נִיסָן ‎ </Td> <Td> Nīsān </Td> <Td> Nisan </Td> <Td> Nissan </Td> <Td> 30 days </Td> <Td> Nisanu </Td> <Td> Passover </Td> <Td> Called Abib (Exodus 13: 4, 23: 15, 34: 18, Deut. 16: 1) and Nisan (Esther 3: 7) in the Tanakh . </Td> </Tr> <Tr> <Td> </Td> <Td> אִיָּר / אייר ‎ </Td> <Td> ʼIyyār </Td> <Td> Iyyar </Td> <Td> Iyar </Td> <Td> 29 days </Td> <Td> Ayaru </Td> <Td> Pesach Sheni Lag B'Omer </Td> <Td> Called Ziv in 1 Kings 6: 1, 6: 37 . </Td> </Tr> <Tr> <Td> </Td> <Td> סִיוָן / סיוון ‎ </Td> <Td> Sīwān </Td> <Td> Sivan </Td> <Td> Siwan </Td> <Td> 30 days </Td> <Td> Simanu </Td> <Td> Shavuot </Td> <Td> </Td> </Tr> <Tr> <Td> </Td> <Td> תַּמּוּז ‎ </Td> <Td> Tammūz </Td> <Td> Tammuz </Td> <Td> Tamuz </Td> <Td> 29 days </Td> <Td> Dumuzu </Td> <Td> Seventeenth of Tammuz </Td> <Td> Named for the Babylonian god Dumuzi </Td> </Tr> <Tr> <Td> 5 </Td> <Td> אָב ‎ </Td> <Td> ʼĀḇ </Td> <Td> Av </Td> <Td> Ab </Td> <Td> 30 days </Td> <Td> Abu </Td> <Td> Tisha B'Av Tu B'Av </Td> <Td> </Td> </Tr> <Tr> <Td> 6 </Td> <Td> אֱלוּל ‎ </Td> <Td> ʼĔlūl </Td> <Td> Elul </Td> <Td> </Td> <Td> 29 days </Td> <Td> Ululu </Td> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td> 7 </Td> <Td> תִּשׁרִי ‎ </Td> <Td> Tišrī </Td> <Td> Tishri </Td> <Td> Tishrei </Td> <Td> 30 days </Td> <Td> Tashritu </Td> <Td> Rosh Hashanah Yom Kippur Sukkot Shemini Atzeret Simchat Torah </Td> <Td> Called Ethanim in 1 Kings 8: 2 .
