But numbers, seasons and dates have their own symbolic values. Do your research. You can celebrate the birth of Jesus when the flowers bloom. Cold, dead December is not it.
Some will say, it doesn't matter when you celebrate it, then why are these people opening portals on this date? Come on people, I believe you can see for yourself something ain't right. You don't have to wait for "Holidays" to do a great meal and celebrate life.
Do what you want but at least do it knowing because ignorance is not bliss and doesn't save anyone.
