| Lunar year | New Year begins | Ends |
|---|---|---|
| 1924 · 甲子 | 1924-02-05 | 1925-01-23 |
| 1984 · 甲子 | 1984-02-02 | 1985-02-19 |
| 2044 · 甲子 | 2044-01-30 | 2045-02-16 |

This narrows possible years but cannot date a document by itself. Boundaries beyond the supported range are labelled instead of extrapolated.
