Tanzania's 2025 general election falls in which millennium?

1. Millennia under the Gregorian calendar are counted in blocks of a thousand years. 2. The 3rd millennium began on 1 January 2001 and runs to 31 December 3000. 3. The year 2025 falls inside that span, so it is in the 3rd millennium. 4. The 2nd millennium ended on 31 December 2000, so 2025 is past it. 5. Answering the 21st confuses the century with the millennium — 2025 is in the 21st century but the 3rd millennium. _Source: NECTA CSEE 2023 History 012, Question 1: Multiple Choice Items, item (i)_
