The second month in the Jewish calendar, consisting always of twenty-nine days, and falling between the tenth of April and the eighth of June (R. H. 3a et passim; Targ. Yer. to Ex. xii. 39; Targ. Sheni to Esth. iii. 7). This month in the Bible is designated as (I Kings vi. 1 = the month of beginning the Temple-building), probably the same as the Phenician or Punic (Lidzbarski, "Nord-Semitische Epigraphik," p. 267). The word "Iyyar" is undoubtedly connected with the root , and thus denominates the month as the month of light, over and against Adar, which etymologically is the dark month. Like all the names of the months, "Iyyar" is a loan-word from the Assyro-Babylonian ("A-a-ru"; see Delitzsch, "Handwörterb." p. 34b). This month falls in the Omer, the first of Iyyar being the sixteenth day of Omer.
