I know this is going to sound like a Yechi thing, but someone in shul pointed out that there are 5770 days between Gimmel Tammuz (The Rebbe's yartzeit in 1994) and the first day of Pessach.
I ran the calculation in Excel and it adds up.
03/30/10 - 06/12/94 = 5770 (format result cell to number instead of date).
Chag Sameach.
