Yes, i do need a holiday, but...

The sun is a month out of alignment. It usually shines in the full length of a building on our farm on about the 20th of June. I know this because we are filling the building with grass then, and every year i wait for the night when the setting sun shines up the valley and into the building where im working a tractor.  Well this evening the sun is doing the same, which means it is considerably higher before it sets than it should be in May.
   The photo ive posted is a view from my old house. and the sun used to set in the Y of the trunk on a certain date ,and that was once a week out. There maybe astronomic reasons for this ? I dont know, but tonights example is a bit more dramatic.
