Use this skill for any task involving Thai date formatting, Buddhist Era (พ.ศ.) ↔ Gregorian (ค.ศ.) year conversion, or Arabic ↔ Thai numeral conversion. Trigger whenever the user asks to: convert พ.ศ. to ค.ศ. or vice versa, format a date in Thai government / business / casual style, parse a Thai date string with full or abbreviated month names, or convert digits between 0123456789 and ๐๑๒๓๔๕๖๗๘๙. Also trigger for requests like "แปลง พ.ศ. เป็น ค.ศ.", "จัดรูปแบบวันที่ไทย", "วันที่แบบราชการ…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Thai Date Format (แปลงวันที่ไทย พ.ศ./ค.ศ.)

## Overview
แปลงระหว่าง พ.ศ. กับ ค.ศ. (`BE = CE + 543`), จัดรูปแบบวันที่ไทยตามสไตล์ราชการ / ธุรกิจ / กันเอง / สั้น, และสลับเลขอารบิก ↔ เลขไทย. Handles full month names (มกราคม) and abbreviations (ม.ค.).

## When to use
- รายงาน/หนังสือราชการที่ต้องการ พ.ศ.
- Parse วันที่จากเอกสาร PDF/Excel ที่ใช้ภาษาไทย
- แสดงผลในแอปสำหรับผู้ใช้ไทย (ทั้งเลขไทยและ พ.ศ.)
- DO NOT use for pre-1941 historical documents where the Thai fiscal year started 1 April; this module assumes Gregorian-aligned years.

## Example prompts
- "แปลง วันที่ 16 พฤษภาคม พ.ศ. 2569 เป็น ISO date"
- "Format วันนี้แบบราชการพร้อมเลขไทย"
- "Parse '๑๖ พ.ค. ๖๙' ให้เป็น Date object"

## Quick reference

### Year conversion
`BE = CE + 543` (e.g., 2026 → 2569). Pre-1941 documents may use a 1 April fiscal-year start — not handled here; convert manually if needed.

How to install

The exact contents, by fingerprint
mdr add boom-vitt/claude-thai-skills/thai-date-format@sha256:febbdb167f34a48c

The line at the top of this page pins the label git:20260517.f1383d3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
