Anyway, to answer Raisa's original question: The holiday was the Islamic new year, since we use a different calendar based on the lunar cycle. In the Islamic calendar (a.k.a. Hijri calendar) the year is 1428.

Our calendar begins from the Islamic migration from Mecca to Yathrib (a.k.a. Al-Madina Al-Munawwara, which translates to "The City of Lights" or "The Enlightened City"). Pretty cool story, it was the turning point for Muslims; they went from being oppressed and persecuted to becoming independent.
