How many fortnights are in one year?
There are 52 weeks in a year. A fortnight is a period of two weeks, sto divide 52 in half gives 26 fortnights in a year. This is more accurate than saying there are 2 fortnights per month - which would work out as 24 fortnights in a year.
Which is longer a fortnight or an annum?
An annum is longer than a fortnight. An annum is a year, which consists of 12 months or 52 weeks, whereas a fortnight is a period of two weeks.

How many weeks in 18 months?
You need to work it out this way We know by definition that there are 52 weeks in 12 months. so: 52/12 = the number of week in 1 month. 4.3333 So if 1 month = 4.3333 weeks, 18 months = 4.3333*18 = 77.9994 weeks.
