The exact number of weeks in a year however is actually just over 52 weeks, as there are either 365 or 366 days in each year, rather than the exact 364 days which is the amount of days there are in 52 weeks.

In a school year, there are anywhere between thirty (30) and forty (40) weeks of school, which in Australia, are divided into four terms of (almost) equal weeks. Therefore, in each semester there are approximately 15 to 20 weeks, and in each term there are around 8 to 10 weeks, which means that holidays account for about one quarter of the year.
