1983 is the year of the Water Pig, from 13 Feb 1983 – 1 Feb 1984. A 1983 birth before 13 Feb 1983 belongs to the previous Water Dog year.
The year's complete signature
The Water year stem and the Pig's fixed Water branch are different coordinates. Their element dynamic is Water meets Water. Both positions carry Water, so the element repeats rather than generating or controlling another element.
The complete 癸亥 pillar carries Na Yin 大海水, a Water classification.
One year, two boundary conventions
Pig from this lunar-calendar boundary.
Pig from this solar-term boundary.
Between the two boundaries, Chinese New Year assigns Dog; Li Chun assigns Pig. On 4 February 1983, the solar answer changes at 4 February 1983 at 17:39 UTC+8.
The moving New Year boundary
Chinese New Year 1983 fell on 13 February 1983. Anyone born between 1 January 1983 and 12 February 1983 — a window of 43 days — belongs to the 1982 zodiac year, the Yang Water Dog, and not to the Pig.

The 1983 lunar year ran its ordinary twelve months, 354 days in total.

The repeating earthly branch
The Pig branch repeats every twelve years. Across five returns, the year stem moves through all five elements; the exact Yin Water Pig signature comes back after sixty years.
Each point is twelve years apart. Element names describe the changing heavenly stem; the animal branch remains Pig. Open a year or complete name for its full record.
