There’s no year 0, it starts at year 1 CE (Common Era, you may also see this written as “AD 1”, Anno Domini 1). The concept of zero is relatively recent, it didn’t exist in its current form when this year numbering system was established.
If you go back one year from there you hit 1 BCE (Before Common Era, also written 1 BC, Before Christ) and start counting up one for each year you go back.
So, 2022 years ago is 1 CE; 2023 years ago is 1 BCE; and 2024 years ago is 2 BCE.
