This year the solstice is timed for 6.37 pm on the 21st. Which lends itself nicely to observing sunset on 21st AND sunrise on 22nd. I'll be keeping a fire going all night to see us through the darkest hours.
Someone once told me that technically the sun is at standstill at solstice and doesnt actually start to return until 3 days later - hence big party on the 25th.
Don't know how true that is.
Be interesting to hear what others think.
