Here's an idea,

To help

I was dreamin' when I wrote this
Forgive me if it goes astray

But when I woke up this mornin'
Coulda sworn it was judgment day

The sky was all purple
There were people runnin' everywhere

Tryin' 2 run from the destruction
U know I didn't even care

'Cuz they say two thousand zero zero party over
Oops out of time
So tonight I'm gonna party like it's 2019

I was dreamin' when I wrote this
So sue me if I go 2 fast

But life is just a party
And parties weren't meant 2 last

War is all around us
My mind says prepare 2 fight

So if I gotta die
I'm gonna listen 2 my body tonight

Yeah, they say two thousand zero zero party over
Oops out of time
So tonight I'm gonna party like it's 2019
Yeah

Lemme tell ya somethin'
If U didn't come 2 party
Don't bother knockin' on my door
I got a lion in my pocket
And baby he's ready 2 roar

Yeah, everybody's got a bomb
We could all die any day
But before I'll let that happen
I'll dance my life away

They say two thousand zero zero party over
Oops out of time
We're runnin' outta time
So tonight we gonna, we gonna (Tonight I'm gonna party like it's 2019)

Say it 1 more time
Two thousand zero zero party over
Oops out of time
No, no
So tonight we gonna, we gonna (Tonight I'm gonna party like it's 2019)

Alright, it's 2019
You say it, 2019
2019
2019 don't stop, don't stop, say it 1 more time

Two thousand zero zero party over
Oops out of time
Yeah, Yeah
So tonight we gonna, we gonna (Tonight I'm gonna party like it's 2019)

Yeah, 2019
Don'tcha wanna go
Don'tcha wanna go
We could all die any day
I don't wanna die
I'd rather dance

This works by

Putting together a big party at the end of this decade on December 31st 2019 to welcome in the 2020 and the 2020s decade.

This is better than

Hopefully even better than when we celebrated the end of the 1990s on December 31st 1999 and the end of the 2000s on December 31st 2009.

Here's a picture

Additional notes

Even though it is still a long, long way off yet, I wish everyone here all the best for the rest of this decade and the 2020s decade!
