How can i set the date to the beginning of calendar

I want to set the time to the 1st January 0000 and time at 00:00:00 i tried to calculate a lot but i’m unable to set the date to the beginning point.

I am setting the date with negative sign like this –

new Date(-4000) but setting the year to 0 gives me only the 1900 so how can get to the perfect date of 1st Jan 0000 and time at 00:00:00.


The way you were doing you can also set it, to -62167219200000 it will return the same results as new Date("0000-01-01")

const d = new Date(-62167219200000);

Only will set the date to 0 not the time
