Hebrews spent almost a year at Mt. Sinai

“We are told in Exodus 19:1 that the Israelites arrive at Mt. Sinai 3 months to the day after they have left Egypt. In Numbers 10:11 they leave Mt. Sinai ‘on the 20th day of the 2nd month of the 2nd year’, about 10 days short of a 12-month stay (at Sinai).”
