Yestarë

Yestarë, meaning 'First-day', was the name used in the Elves' calendars, and those derived from them, for the first day of the year. The actual date of yestarë varied from calendar to calendar; according to the Reckoning of Rivendell, it fell on modern 28 March, while in the calendars of the Númenóreans and their descendants, its modern equivalent would be 22 December.
