The Jewish calendar is lunar, so 1/6 of all eclipses occur on Passover and Sukkot.
There have been
sixty-two tetrads since the first century CE, and
eight of them have coincided with both feasts.
Additionally, three of the four eclipses in this year's tetrad won't even be visible from Israel.
In short, this is just more Christian sensationalism from people trying to scare folks into joining their religion.
