Why do we celebrate New year?

What is new in new year? what are the changes that we need to celebrate. I dont get it. I mean anyone who wants to party can do that on weekends. What's so different?

It is just recharging mind with new start with great enthusiasm.

To forget past memories and with the dreams of future, to live in a present.

Actually you said, nothing is changing, still it depends on one's mindset.

For different person thinking is varied...actually everyday is new start ...also i can say each moment is new hope.

Still we have to bound time in calendars, in days-months-years. We have to follow a sequence.

Then why should we not select with new year day only ?!! To boost up positivity.

And new year is not only about celebrating in parties...it is just a tradition which some follow some not.

We can discuss in detail for New way of thinking with another chance philosophically.

But then, again, when I think more about it... considering how in universe there's never 'fixed' point, even when Earth does keep going around the Sun in a seemingly constant manner, I realise the sillyness of the whole thing...

For me, I take 'new year' (or even birthday) in material sense, in a way to make sense of my own life - it's been 365 days, where am I, what am I doing blah blah blah.

And, I'll be honest, I do feel sentimental about new year, I'm a sentimental person.. because no matter how vague the day might be in the real sense, it is the beginning of an year in the practical functional sense of the world. I do buy sweets for myself on new year's.. and wish everyone.. Maybe it's just an opportunity to give well-wishes to people expressly, we can do that other times too but it's a little different on New Year's because everyone is in almost same mood - either bad/good/excited/nervous/anxious/prayerful/whatever.. I like that we all have similar hopes for getting better in life during those 2-3 days - it's wonderful how everyone across the world more or less feels sentimental or atleast feel something if anything - about new year.

Partying and all, I don't understand it for any occasion tbh.

Also! my dad's birthday is on Jan 2, so, it adds to the sentiment I cannot explain.. :-)
