Sukkot & Simchat Torah

Sukkot was agricultural in origin. This is evident from the name "The Feast of Ingathering," from the ceremonies accompanying it, and from the season and occasion of its celebration: "At the end of the year when you gather in your labors out of the field" (Ex. 23:16); "after you have gathered in from your threshing-floor and from your winepress" (Deut. 16:13). It was a thanksgiving for the fruit harvest (compare Judges 9:27). And in what may explain the festival’s name, Isaiah reports that grape harvesters kept booths in their vineyards (Isa. 1:8). Coming as it did at the completion of the harvest, Sukkot was regarded as a general thanksgiving for the bounty of nature in the year that had passed.

Simchat Torah (also Simchas Torah, Hebrew: שמחת תורה, lit., "Rejoicing with/of the Torah,") is a celebration marking the conclusion of the annual cycle of public Torah readings, and the beginning of a new cycle. Simchat Torah is a component of the Biblical Jewish holiday of Shemini Atzeret, which follows immediately after the festival of Sukkot in the month of Tishrei (mid-September to early October on the Gregorian calendar).
