Being born in 2021
Anyone born in 2021 turns 5 at some point during 2026. Until their birthday arrives they are still 4, which is why an age calculator that only knows the year can never give one answer. Enter the full date above and the number becomes exact, down to the second.
2021 makes you Gen Alpha, and in the Chinese calendar it was the Year of the Ox.
What 2021 looked like
CODA won Best Picture and Spider-Man: No Way Home was the biggest film at the box office. In the news, 2021 was the year of the Tokyo Olympics, held a year late.
The world in 2021
There were about 7.91 billion people alive, against roughly 8.25 billion today. Atmospheric CO₂ stood near 416 ppm, compared with about 427 ppm now. And money went further: $100 in 2021 bought roughly what $120 buys today.
Sport around 2021
The nearest Summer Olympics were held in Tokyo in 2020. The closest World Cup was won by Argentina in 2022. Around then, the moment people still talk about was Messi finally lifts the World Cup.
