Since a Jewish week of years is 7 years long, and a week of days is 7 days long, would 1 day called the Day of the Lord be 1 year long?

The great tribulation is 3 1/2 yrs. long, 42 months or 1,260 days long.  So will the great multitude of saints seen in heaven after the 6th seal is open only be here on Earth for the first 2 1/2 years or 900 days of the great tribulation period of 1,260 which would leave 1 year of 360 days (Day of the Lord) for all the 7 Trumpets judgments and 7 Bowl judgments to be poured out on the unbelievers?
