Approximately every seven months there is a week-long Sabbath. This is a pause in the seventh cycle of months. There are two of these festivals each year and all the people traveled to Jerusalem to celebrate. The first of these one week long, Seventh Month Sabbaths occurs on the 15th day of the 1st month of every year and is known as the "Feast of Unleavened Bread":

... on the fifteenth day of this month is Yahweh’s Feast of Unleavened Bread; for seven days you shall eat unleavened bread. On the first day there shall be a holy assembly for you; you shall not do any regular work. And you shall present an offering for Yahweh made by fire for seven days; on the seventh day there shall be a holy assembly; you shall not do any regular work. Leviticus 23:5-8

Then Yahweh spoke to Moses, saying, “Speak to the Israelites, saying, ‘On the fifteenth day of the seventh month, this shall be the Feast of Booths for seven days for Yahweh. On the first day there shall be a holy assembly; you must not do any regular work. For seven days you must present an offering made by fire to Yahweh. On the eighth day it shall be a holy assembly for you, and you shall present an offering made by fire to Yahweh; it is a celebration; you must not do any regular work. Leviticus 23:33-36
