Tu b’Shvat Seder
Question
B"H I was discussing the Tu B'Shevat seder with a friend, and he informed me that there is concern that the tradition comes from a Shabbatain (did I get that right?) practice. I looked it up, and discovered that it comes from Sefer Hemdat Yamim. So I guess my question is, "Who wrote Sefer Hemdat Yamim?" I can't seem to find anything about this online. Shavua Tov, Aliya
