I have a couple of ones i personally observe that i started on my own as a way to honor the passing of the old year into the new.
I do them just for fun...and to give myself a little positive push into the New Year.
It puts me into a great mindset and works wonders for me.
First and foremost is to always wear a brand new piece of clothing, usually a shirt, on New Years day.
It represents a new beginning and wearing something worn previously may carry over negative energies.
The item is usually brightly colored, often yellow or green which are colors traditionally associated with prosperity and growth.
The other major tradition is to be mindful of what it is you do on New Years Day.
Whatever activity or mindset you are in may well dictate what you will be doing in the New Year.
So you don't want to do anything that you do not really like or enjoy...and it is not a good day for 'finishing' anything.
It's all about 'starting' and new beginnings.
Leave the dust of last year behind.
I would say my favorite tradition is observing the weather on New Years day.
It is indeed a wonderful year ahead if it is a bright, clear, and sunny day!
