Ding Si · 丁巳
1977 is the year of the Fire Snake, from 18 Feb 1977 – 6 Feb 1978. A 1977 birth before 18 Feb 1977 belongs to the previous Fire Dragon year.
The year's complete signature
The Fire year stem and the Snake's fixed Fire branch are different coordinates. Their element dynamic is Fire meets Fire. Both positions carry Fire, so the element repeats rather than generating or controlling another element.
The complete 丁巳 pillar carries Na Yin 沙中土, a Earth classification.
One year, two boundary conventions
Snake from this lunar-calendar boundary.
Snake from this solar-term boundary.
Between the two boundaries, Chinese New Year assigns Dragon; Li Chun assigns Snake. On 4 February 1977, the solar answer changes at 4 February 1977 at 06:33 UTC+8.
The moving New Year boundary
Chinese New Year 1977 fell on 18 February 1977. Anyone born between 1 January 1977 and 17 February 1977 — a window of 48 days — belongs to the 1976 zodiac year, the Yang Fire Dragon, and not to the Snake.

The 1977 lunar year ran its ordinary twelve months, 354 days in total.
The Gregorian year's solar clock

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