Heshvan or Nisan?

Aliyah Day. Is it Heshvan or Nisan? March or October? Please excuse the confusion. Yom HaAliyah is celebrated on the tenth of the Hebrew month of Nisan and ALSO (apparently) on the seventh of the Hebrew month of Heshvan, to commemorate the Biblical account of the Israelites entering the Land of Israel!
It's the kind of confusion and necessary disagreement that we locals are used to. * * * The LSW (Long Suffering Wife) and I LOVE living in Israel and turning out Dry Bones cartoons to defend our maligned little country. But we do this work out of our empty pockets. This means that we are forced to ask fans and followers for help.

We both can assure those who are answering our call that we are grateful for your love and support.
