Yes, it is interesting. The reason is that both are based on the phases of the moon which do not match up with the Gregorian calendar.
Specifically, Easter is the first Sunday after the first full moon on or after March 21st. The timing of a full moon on or after any given day can vary by as much as 29 days.
The Jewish calendar is a lunar calendar with the first day of each month being at the new moon. Passover is always the 14th day of the month of Nisan, which would be at a full moon day (half way between two new moons). The 1st day of the month of Nisan also varies by as much as 29 days with respect to the Gregorian calendar.
Have you noticed that Hanukkah can also vary from late November to late December?
