As for my name—אתמולתיים, read Etmoltayim, is the Hebrewdual form applied to "אתמול", as in, yesterday, meaning "the day before yesterday", the same way "מחר" means tomorrow and "מחרתיים" means "the day after tomorrow"; The proper Hebrew word for the concept is שלשום, meaning (loose translation) "day of the third rank". Ironically, שלשום is the 'proper', biblical word, and in modern Hebrew, the dual form is mostly obsolete, though slowly returning (partially thanks to the influence of Palestinian).
