Can do Havdalah this year on Rosh Hashanah 2020/5780 in Motzei Shabat, who lives in galut?
Answer:
For Rosh Hashana even those living in Eretz Yisroel have two days of Yom Tov. When Yom Tov is on Motzei Shabbos, we say a special kiddush which adds a bracha for בורא מאורי האש and another special bracha for havdalah between Shabbos and Yom Tov. You can find the text in your machzor..
