Jewish organizations will often send out calendars because the Jewish calendar differs from the secular calendar.
It’s helpful for planning holidays, etc.
It’s also typical for the organization to choose Jewish or Israel-themed pictures for the calendar.
I was particularly struck by the choice that Danzansky-Goldberg Memorial Chapels made this year when their theme was “The Dead Sea.”
Not sure this would have been my first choice, but there’s no doubt that it’s probably the strongest Israel-themed idea which directly connects to their brand and core business.
