Japanese Era & Thai Buddhist Date Converter
Non-Gregorian calendar systems are used in production systems daily: Japanese era dates (`令和8年8月13日`, Reiwa 8 = 2026), Thai Buddhist (BE = CE + 543, so 2026 CE = 2569 BE), and Chinese common formats (`2026年8月13日`).
This converter renders your date-time in each localized form so you can test locale handling, generate era-based labels, and avoid off-by-543 bugs in Thai systems.
