In an astrological sense birthdays are quite important because they indicate when the soul can incarnate in fitting with planetary and solar harmony and therefore karmic background. How ever since Jesus was most likely not even born in December, we have quite a reason not to celebrate. This time of year, has been a pleasant time to celebrate because it gives us all something to take our minds off the most challenging weather this time of year.
I know about the astrological importance, but I can't accept that since man made up what a day is, based on how long it takes for the earth to complete 1 rotation, (actually how long is day to night and night to day), then how long it takes for the earth to complete 1 rotation around the sun, then tell me I'm x number of years old, doesn't calculate for me. Physical clocks do not prove time even exists. IMO. But I see the usefulness of it at least, too late to turn back now aint it.
I rather enjoyed the very cold weather, we were around 19 degrees, layer of ice for a few days. I know a guy who must have as perfect (to him) weather all the time, like for example La Jolla CA. But to me that's monotonous, I like rain, snow, ice, clouds, sun, all of it. For me the weather took my mind off this time of year for a bit.
