干支换算工具Sexagenary Converter
干支 ↔ 公历年份
Ganzhi ↔ Gregorian
输入公元年份换算六十甲子，或选择干支列出候选公历年份（可叠加明清年号限定）。
Convert a Gregorian year into its sexagenary pair, or pick a ganzhi to list candidate years — optionally narrowed by a Ming or Qing reign title.
① 公历年份 → 干支① Gregorian year → ganzhi
可输入 1–3000 年，按整年换算，不区分月日。适用于东汉及以后的干支纪年。Enter a year from 1 to 3000. The conversion is year-based and ignores month and day.
② 干支 → 公历年份② Ganzhi → Gregorian years
六十甲子顺序：甲子、乙丑、丙寅……癸亥。The 60-term cycle runs Jiazi, Yichou, Bingyin … Guihai.
选择年号后只在该年号纪年范围内查找，可快速缩小候选年份。Selecting a reign title restricts the search to that reign.
