The exact dates of the 2021 lunar year
The Metal Ox year ran from February 12, 2021 to January 31, 2022. Twelve lunar months came to 354 days in 2021, eleven or twelve short of the solar year, and that shortfall is what pulls the following new year back towards January.
The 2021 new year fell 18 days later in the Gregorian year than the 2020 one, February 12, 2021 against January 25, 2020. Why the 2021 boundary sits where it does, rather than on any fixed date, is worked through in how the Chinese calendar works.
What the Metal Ox pairing is taken to mean
The stem for 2021 is Xin and the branch is the Ox, which the tradition reads as one unit rather than two. In 2021 that branch is taken to mean someone patient and immovable, doing the work whether or not anyone is counting it. Metal, the element attached to 2021, adds definition, resolve and a preference for clean edges.
2021 is a yin year, the inward half of the Metal pair: 2020 carries the same element in its yang form, and the two are read as the same material handled differently. Taken together, 2021 is described as the ox temperament working through definition.
Born in January or early February 2021
From 1 January 2021 to February 11, 2021 the animal in force was still the Rat, not the Ox — 42 days of 2021 that most zodiac tables hand to the wrong animal. Someone born on 15 January 2021 is a Rat.
The first Ox of 2021 is anyone born on February 12, 2021 or later, and the last one anyone born on January 31, 2022. Against the 21 January to 20 February window the new year can occupy, February 12, 2021 is at the later end.
Where 2021 sits in the sixty-year cycle
2021 is position 38 of sixty in the sexagenary cycle, the Xin stem against the Ox branch. Ten stems and twelve branches only realign after sixty years, so the previous Metal Ox year was 1961 and the next is 2081.
Someone born in 1961 therefore returned to their own pillar in 2021, at sixty, which the tradition marks as a full turn rather than a birthday. A child born in 2021 meets the pairing again in 2081.
Compatibility, and what it rests on
The Ox of 2021 is grouped with the Snake and the Rooster, four years either side: in this stretch of the calendar that is 2017 and 2025. Its opposition is the Goat, six years on from 2021 in 2027.
Those distances are arithmetic, not observation. Nothing about people born in 2021 was measured to produce them; 2021 stands four years from 2017 and six from 2027, and a twelve-part circle makes those the trine and the opposition just as it does in the western zodiac.
The western comparison for 2021
Because the 2021 lunar year opened on February 12, 2021, its first day falls under Aquarius in the western zodiac, and its last, January 31, 2022, under Aquarius — while the animal for the whole of 2021 stays the Ox.
Handbooks equate the Ox of 2021 with Capricorn, a pairing that lines up two twelve-part divisions rather than two claims about people. A western sign covers about thirty days, so 2021 holds twelve of them under one animal, and reading the 2021 Metal Ox as a year-long version of Capricorn flattens both systems.
