In Eretz Yisroel in the month of Tishrei there are 11 days of Yom Tov.
2 days Rosh HaShana, 1 day Yom Kippur, 8 days Succos.

The first auto-da-fé of the Inquisition in Spain was in 1481. According to Lee J. Levinger, "[t]he last execution [in Spain] on a charge of backsliding to Judaism was held in 1745, two hundred and sixty-four years later".
In a leap year, Yom Yerushalayim is the 264th day in the year if Heshvan and Kislev are both Haserim (have 29 days):
Tishrei -30 days
Heshvan, Kislev, Tevet - 29 days each
Shvat - 30 days
Adar A - 29 days
Adar B - 30 days
Nisan - 30 days
Iyar - 28 days (Yom Yerushalayim is on the 28th day of Iyar)
