On Sukkot Jewish families build a temporary hut (sukkah) with an open roof made of branches to let in moonlight and an open side to welcome guests.
Sukkot is a time to host guests for meals in the sukkah. The open booth is a reminder of how the Children of Israel slept after they fled slavery in Egypt, a connection to the story of Pesach. It also resembles temporary shelters from the sun used by farmers planting out in the fields.
