Hi, I think the date for Leil Slichot 5720 is not correct on this page: https://www.hebcal.com/holidays/ It should be Sept. 21. It is correct on the detail page for Leil Slichot.

Please check the Aliyot divisions for Sefer Davarim, Parshat V'Etchanan, third year. I think they are not correct. The Ten Commandments should be on unbroken Aliyah. Also, it does not match the Rabbinic Assembly.
