At approximately 1736 Zulu, Spring started, marking the Iranian New Year.
An older New Year tradition than that of January 1st, it is the holiday that brings together Iranians of all backgrounds (Moslems, Jews, Armenians, Azeris, Kurds, Persians, etc.).
So set out your haft seen, eat way too many nuts, fruit and cookies and drink enough tea to keep you up for a year. Here's to a happy and prosperous New Year.
