ADLOYADA (Heb. עַדְלָיָדַע; Aramaic עַד דְּלָא יָדַע), Purim carnival. The name is derived from the rabbinic saying (Meg. 7b) that one should revel on Purim until one no longer knows (ad de-lo yada) the difference between "Blessed be Mordecai" and "Cursed be Haman." The first Adloyada was held in Tel Aviv (1912) and spread to other communities in Israel. It is celebrated by carnival processions with decorated floats through the main streets, accompanied by bands.
