It depends on which months, obviously, as a month that has 31 days will have more hours than one that has 30.
1,350 hours = about 1.85 months (1.84808875 months)
8,000 hours = about 11 months (10.9516371 months)
As there are a differing number of days in the months, the exact number of months in 4160 hours would depend upon the start date and time of the hours. I will assume a day of 24 hours and a regular month of 365.25 days/year ÷ 12 month/year = 365.25 days/year ÷ 12 month/year × 24 hours/day = 730.5 hours/month to give an approximation 4160 hours ÷ 730.5 hours/month ≈ 5.69 months ≈ 5 months 3 weeks. There are approximately 5.69 months, which is approximately 5 months 3 weeks in 4,160 hours.
1,200 hours is ~1.642746 months.
1215 hours is 50.63 days or 1 month 20 days 5 hours. 1215 months is 886950 hours.
