No. Number of fortnights in a year = 365/14 = 26.07 (approx) which is fewer than the number of days in any month.
fewer children are needed as producers.

A compressed workweek has you working 40 hours in fewer than five days. The most widely used schedule is 10 hour days for four days a week.
It has rotated through an angle of a bit more than 2pi radians (360 degrees) with respect to the distant fixed stars during the past 24 hours.
A convocation cannot typically be had within 15 days. Most degree programs will last longer than two weeks. Certificate programs may turn out in fewer days.
A shape that has fewer than 8 faces and fewer than 10 edges is a triangular prism. A triangular prism has 5 faces (2 triangular faces and 3 rectangular faces) and 9 edges. It meets the criteria of having fewer than 8 faces and fewer than 10 edges.
A year on Venus is shorter than a year on Earth, but a "day" on Venus is much longer than a day on Earth. I'm not sure exactly what you were trying to ask, but that should about cover it.
