Reading megilah on Yom Tov

Hi,

If a shul normally reads the megillah on Succot (Kohelet) or Pesach (Shir haShirim) from a parchment and with a berachah, and they are not able to get a megillah until the last days of Yom Tov, so that they will have missed Shabbat Chol haMoed, they may wait for Yom Tov and read then, with a berachah. The goal of reading on Shabbat was to locate the reading on the day when most people come to shul, but the reading may be done on Yom Tov.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 4:99:2)

Have a great day,
Mordechai
