2020s in the context of 2023

2025 (MMXXV) is the current year, and is a common year starting on Wednesday of the Gregorian calendar, the 2025th year of the Common Era (CE) and Anno Domini (AD) designations, the 25th year of the 3rd millennium and the 21st century, and the 6th year of the 2020s decade.

So far, the year has seen an escalation of major armed conflicts, including the Russian invasion of Ukraine, which began peace negotiations involving Vladimir Putin and Donald Trump. The Gaza war, including a famine and humanitarian crisis, as well as the Sudanese civil war, also continued throughout the year. Internal crises in Armenia, Bangladesh, Ecuador, France, Georgia, Germany, Haiti, Peru, Somalia, and South Korea continued into this year, with the latter leading to President Yoon Suk Yeol's arrest and removal from office. The year has also seen a wave of protests predominantly led by Generation Z, with some, like those in Nepal and Madagascar, resulting in the overthrow of governments. Several brief conflicts out of longstanding tensions emerged mid-year—India–Pakistan in May, Iran–Israel in June, and Cambodia–Thailand in July, in which a leaked phone call involving Thai prime minister Paetongtarn Shinawatra and Cambodian senate president Hun Sen resulted in the removal of the former.

2021 (MMXXI) was a common year starting on Friday of the Gregorian calendar, the 2021st year of the Common Era (CE) and Anno Domini (AD) designations, the 21st year of the 3rd millennium and the 21st century, and the 2nd year of the 2020s decade.

Like the year 2020, 2021 saw the year by the COVID-19 pandemic ongoing, due to the emergence of multiple COVID-19 variants. The major global rollout of COVID-19 vaccines, which began at the end of 2020, continued in 2021. Most major events scheduled for 2020 that were postponed due to the pandemic were hosted in 2021, including the 26th United Nations Climate Change Conference (held in Glasgow, Scotland), Expo 2020 (held in Dubai, United Arab Emirates), and sporting events such as UEFA Euro 2020 (held across 11 European countries), the 2020 Summer Olympics and Paralympics (both held in Tokyo, Japan), as well as the 2021 Copa América (held in Brazil).

2027 (MMXXVII) is the upcoming year, which will be a common year starting on Friday of the Gregorian calendar, the 2027th year of the Common Era (CE) and Anno Domini (AD) designations, the 27th year of the 3rd millennium and the 21st century, and the 8th year of the 2020s decade.

2022 (MMXXII) was a common year starting on Saturday of the Gregorian calendar, the 2022nd year of the Common Era (CE) and Anno Domini (AD) designations, the 22nd year of the 3rd millennium and the 21st century, and the 3rd year of the 2020s decade.

The year began with another wave in the COVID-19 pandemic, with Omicron spreading rapidly and becoming the dominant variant of the SARS-CoV-2 virus worldwide. Tracking a decrease in cases and deaths, 2022 saw the removal of most COVID-19 restrictions and the reopening of international borders in the vast majority of countries, while the global rollout of COVID-19 vaccines continued. The global economic recovery from the pandemic continued, though many countries experienced an ongoing inflation surge; in response, many central banks raised their interest rates to landmark levels. The world population reached eight billion people in 2022. The year also witnessed numerous natural disasters, including two devastating Atlantic hurricanes (Fiona and Ian), and the most powerful volcano eruption of the century so far. The later part of the year also saw the first public release of ChatGPT by OpenAI starting an arms race in artificial intelligence which increased in intensity into 2023, as well as the collapse of the cryptocurrency exchange FTX.

2028 (MMXXVIII) will be a leap year starting on Saturday of the Gregorian calendar, the 2028th year of the Common Era (CE) and Anno Domini (AD) designations, the 28th year of the 3rd millennium and the 21st century, and the 9th year of the 2020s decade.

2029 (MMXXIX) will be a common year starting on Monday of the Gregorian calendar, the 2029th year of the Common Era (CE) and Anno Domini (AD) designations, the 29th year of the 3rd millennium and the 21st century, and the 10th and last year of the 2020s decade.

2024 (MMXXIV) was a leap year starting on Monday of the Gregorian calendar, the 2024th year of the Common Era (CE) and Anno Domini (AD) designations, the 24th year of the 3rd millennium and the 21st century, and the 5th year of the 2020s decade.

The year saw the continuation of major armed conflicts, including the Russian invasion of Ukraine, the Myanmar civil war, the Sudanese civil war, and the Islamist insurgency in the Sahel. Israel's war on Gaza led to widespread protests and spillover conflicts into numerous other countries, most notably Lebanon, which was invaded by Israel in October. This followed an intensification of the ongoing conflict between Israel and Hezbollah. In September, Israel escalated an offensive against the group, which resulted in the killing of the Secretary-General, Hassan Nasrallah. Ismail Haniyeh, the political leader of Hamas, had also been assassinated in the Iranian capital Tehran in July, and his successor Yahya Sinwar was killed by the Israel Defense Forces in October. In November, heavy fighting resumed in the Syrian civil war, leading to the toppling of Ba'athist Syria, with Bashar al-Assad fleeing Syria in December. The year also saw a rise in activity by the Houthi movement which contributed to a crisis in the Red Sea that impacted global shipping.

2026 (MMXXVI) is the current year, and is a common year starting on Thursday of the Gregorian calendar, the 2026th year of the Common Era (CE) and Anno Domini (AD) designations, the 26th year of the 3rd millennium and the 21st century, and the 7th year of the 2020s decade.
