I hate to be a party pooper but the days don't actually start to get longer until Christmas Day. We now have 3 days of darkness and the sun will start to rise again on 25th December.
It is why 25th December has been a day of celebration since long before the Christian faith jumped on the band wagon and called it Christmas. The ancient Egyptians, the Pagans and many others celebrated it as a sun worshipping festival and had their own stories relating to it.
That said it is a good excuse for a party and now we have hit rock bottom the only way is up (for the sun that is)
