Injuries from dance span all ages, but the risk of injury is greatest during a young dancerâs growth spurt. This is usually between the ages of 8 to 12 for girls and 10 to 14 for boys. During this period, a childâs bones are the weakest, which places the dancer at high risk for fractures (broken bones) and stress fractures (small cracks in a bone).
Since summer (and other seasons) can begin and end on different days each year on the astronomical calendar, it can be hard to compare seasons from year to year in this way. To standardize the length and start of the seasons, in meteorology, the 12 months of the year have been split up into four, 3-month periods. Therefore, in the meteorological calendar, summer includes the months of June, July and August - always starting on 1 June and ending on 31 August.
(Summer is June, July, August; autumn is September, October, November; winter is December, January, February.) For the Southern Hemisphere, seasons are switched, with spring in September, October and November.
