There are two methods of counting decades in recognition. One counts decades starting with the first year 1 CE (For example, the years 1981-1990 is referred to as the 199th decade), while the other groups years based on having the same digits (For example, the years 1980-1989 is referred to as the 1980s, or commonly known as the eighties).
A YouGov poll was conducted on December 2, 2019, asking 13,582 Americans whether the following decade would begin on New Years Day 2020 or New Years Day 2021. Results show that 64% of Americans answered the next decade will begin on January 1, 2020, and will end on December 31, 2029. 19% of the Americans surveyed replied they are unsure, while 17% answered the next decade will begin on January 1, 2021, and will end on December 31, 2030.

Через год можно будет снова запостить.
Не благодари.
