The day has come (and passed) when the sun actually reaches our kitchen window over the neighbours’ house in the afternoon. It still went behind the roof last weekend but above it today so the turning point was some time this week.

In Swedish I think of it as vårtakjämning. The vernal equitectum doesn’t quite have the same ring to it. In Estonian perhaps katuseharjapäev, to go with taliharjapäev?
