Answer 1

geoffc's comment gave me an idea:

236 words in Krias Shema (out of the total of 248, including, as the case may be, א-ל מלך נאמן or the repetition of אני ה' אלקיכם or ה' אלקיכם אמת) are where we are accepting on ourselves Hashem's mitzvos. (The remaining 12 - the first verse of Shema, and ברוך שם - are the acceptance of His kingship.)

(Shulchan Aruch, Orach Chaim 61:14)

Answer 2

In a non-leap year, Yom Yerushalayim is the 236th day in the year if Heshvan and Kislev are both Mele'im (have 30 days):

Tishrei, Heshvan, Kislev - 30 days each
Tevet - 29 days
Shvat - 30 days
Adar - 29 days
Nisan - 30 days
Iyar - 28 days (Yom Yerushalayim is on the 28th day of Iyar)
