Too many winters

I am in the midst of my 53rd Winter. So far I have experienced 50 Autumns and 48 Springs, but only 47 Summers. How old am I? Why am I procrastinating Summer?

One of the benefits of international travel is that I can spend time in different hemispheres, experiencing the different food, culture, and people of the world. I grew up in the Southern Hemisphere where Christmas is in Summer and the school year matches the calendar year. But, 14 and a bit years ago I moved to the Northern Hemisphere for work and a different lifestyle. I now get a real Winter Christmas and the academic year spans two calendar years with a long break in the Northern Hemisphere Summer/Southern Hemisphere Winter.

One of the drawbacks of living on the other side of the equator from family and friends is the opposite seasons. With my immediate family in school, our local long Summer break is the only practical time for us to visit our antipodean whanau, who are then in the midst of their Winter.

Unseasonal days experienced during the season have not been counted, only prolonged exposure to the season experienced by the rest of the hemisphere at that time.

For the purposes of my calculations, a season is counted if I was in a hemisphere experiencing any part of that season at the time. If I visit an opposite season and return before the end of the original season, the original season is only counted once – for example, I left the Northern Hemisphere Summer in June 2016, had four weeks of Southern Hemisphere Winter and returned to experience the remainder of the Northern Hemisphere Summer; earlier/later in the year I had another whole Northern Hemisphere Winter. I have only counted a season if I experienced it for at least one week – I do not remember any of the 21.5 hours of the summer of my birth.

I am using the Meteorological definition of seasons:
Southern Autumn / Northern Spring: 1 March to 31 May
Southern Winter / Northern Summer: 1 June to 31 August
Southern Spring / Northern Autumn: 1 September to 30 November 
Southern Summer / Northern Winter: 1 December to 28 (29 in leap years) February
