Practically speaking, when lambing starts and the tits come back to our nesting box. So, a few weeks ago. From a calendar point of view, the spring equinox is the middle of springtime, so 6.5 weeks before that ie. early Feb. Climatewise, it's probably more like late March, give or take (not this year though, the wintery weather has been shorter than usual). Although in my view the summer starts in mid May, climatewise (ie. the seasons aren't equal length, winter's about 4 months and summer likewise with the others about 2 months in length).
