There are twelve months in a year because the length of a year is determined by how long it takes for the earth
to complete it's orbit around the sun (365 1/4 days).
The moon orbits around the earth about every 29 days - that's a lunar month. If you divide 365 1/4 days by 29 days, you get about 12 1/2 lunar months in a year. So to have an even number of months in the year, days were added to some of the 12 months to get us to the 365 days (366 in leap years) so that we would have an even 12 months (calendar months) in a year
The words month and moon are derived from the same origin because a month was originally the length of one full cycle of moon phases. There are twelve full lunar cycles in one tropical year (with about eleven days left over). When the Roman calendar, the predecessor to our calendar, was lenthened from 355 days to 365 days, the twelve divisions of the year were kept, even though they no longer coincided with the lunar phases.
The moon rotates around the earth approximately 12 times in a year.
Because that's how long it takes the earth to circle around the sun.
144 months in 12 years.
# of years x 12= # of months (cause there are 12 months in a year) Convert 6.7 years to months
there are 12 months in a year. multiply the number of years by 12. Example: How many months are there in 5 years? 12*5=60 there are 60 months in 5 years
12 months = 1 year so 36 months = 36/12 = 3 years.
there are 168 months in 14 years 12x14= 168 12+12+12+12+12=60 > 5 years 12+12+12+12+12=60 > 10 years 12+12+12+12=48 > 14 years total 168 months
14 months = 1 year and 2 months or 12/12 years.
There are 144 months in 12 years. (1 year=12 months).
There are 12 months in a year, so there are 12 billion months in a billion years.
1 year = 12 months12 years = (12 x 12) = 144 months
12 months = 1 year so 140 months = 140/12 years = 11.66... years.
12 million months 1 million years = 1000000 years 1 year = 12 months You know that 1 year has 12 months, so 1000000 years has x months. You set up an equation: 1/12 = 1000000/x x = 1000000*12 = 12000000 months = 12 million months
There are 12 months in one year. Therefore, 90 months is equal to 90/12 = 7.5 years.
