Khmer Hybrid Calendar Meets AI: Introducing My MCP Server

Heng LOEM — Fri, 09 Oct 2026 03:10:40 +0000

I'm excited to share a new milestone in my development journey: Khmer Hybrid Calendar now has its own Model Context Protocol (MCP) server! 🇰🇭

🔗 MCP Endpoint: https://khc.loemheng.com/mcp

💡 From Calendar Application to AI Integration
Khmer Hybrid Calendar started with a simple idea: make Khmer calendar information more accessible and convenient for everyday use.

But I began thinking about a bigger possibility.

What if AI assistants and other AI-powered applications could access Khmer calendar information directly, instead of relying only on web searches or manually looking up dates?

That question inspired me to explore the Model Context Protocol (MCP).

Now, I've successfully integrated an MCP server into Khmer Hybrid Calendar, opening a new way for AI applications to interact with Khmer calendar functionality.

🤖 What Does This Mean?
MCP provides a standardized way for compatible AI applications to connect to external tools and data sources.

With this integration, Khmer Hybrid Calendar can expose its calendar capabilities through MCP tools, making it possible for compatible AI clients to request supported information programmatically.

Depending on the tools available, this can include:

📅 Khmer calendar date information<
🔄 Gregorian and Khmer date conversion
🎉 Khmer holiday information
🪷 Buddhist and religious events
🗓️ Monthly calendar information

Instead of treating Khmer calendar data as something available only inside a website or application, this approach makes it possible to bring that information into AI-powered workflows.

🛠️ Why I Built This
As a developer, I believe our projects should continue to evolve with new technologies.

MCP opens opportunities to connect Khmer Hybrid Calendar with AI assistants, developer tools, automation workflows, and other compatible applications.

My goal is to make Khmer calendar information easier for developers and AI systems to access, while continuing to build on the existing calendar engine.

This is not about replacing the original application. It's about extending its capabilities and creating more possibilities for future integrations.

🌱 What's Next?
This is an early step toward a broader vision: making Khmer calendar information more accessible through developer-friendly APIs and AI integrations.

I'm looking forward to exploring more use cases, improving the integration, and making Khmer calendar technology useful to more people.

Sometimes, a small technical experiment can open the door to much bigger ideas.

Khmer Hybrid Calendar is no longer just about displaying dates. It's also about exploring how Khmer calendar knowledge can connect with the AI ecosystem.

🇰🇭 Built with purpose. Inspired by Khmer culture. Designed for the future.

Khmer Hybrid Calendar v1.1.0 Released — Complete Holidays, UNESCO Heritage & 10x Faster 🚀

Heng LOEM — Wed, 30 Sep 2026 10:58:55 +0000

Excited to announce the release of khmer-hybrid-calendar v1.1.0 on npm! 🇰🇭✨

If you're building applications that need Cambodian holidays, Khmer lunar dates, Buddhist observance days (ថ្ងៃសីល/ថ្ងៃកោរ), or international & Chinese calendar integrations, this update brings major enhancements and performance improvements.

📦 What's New in v1.1.0

1. 🪷 Expanded Buddhist & Khmer Lunar Observances

Buddhist Lent Ceremonies: Added Candle Making Day (ពិធីសិតទៀន), Dragon Monk Ordination (បំបួសនាគខ្នាន), and Lent Entry (ចូលព្រះវស្សា).
Dynamic Waning Observances: Accurate waning Kaor day (ថ្ងៃកោរ) and end-of-month Sil day (ថ្ងៃសីល ដាច់ខែ) calculated for 29 vs 30-day lunar months.
Pchum Ben Closing Day: Added the final transition day (ថ្ងៃឆ្លងភ្ជុំបិណ្ឌ).

2. 🏛️ Cambodian National & UNESCO Heritage Days

UNESCO World & Intangible Heritage: Added anniversaries for Koh Ker, Kun Lbokator, Khmer Krama, Royal Ballet, Sbek Thom, Chapei Dang Veng, and Tuol Sleng Archives.
Historical Observances: National Fish Day, Cambodia's UNESCO accession, and official commemoration days.

3. 🌍 54 International & Chinese Calendar Observances

Expanded to 54 official international days (UN & global observances).
Added Chinese New Year's Eve (ថ្ងៃសែនចូលឆ្នាំចិន) and festival calculations.

4. ⚡ 10x Performance Boost

Optimized astronomical ephemeris calculations and date-range filtering, cutting generation times by over 90%.

🚀 Quick Start

npm install khmer-hybrid-calendar

import calendar from 'khmer-hybrid-calendar';

// Convert Gregorian to Khmer Lunar Date
const khmerDate = calendar.gregorianToKhmer(2026, 4, 14);
console.log(`${khmerDate.lunarDay} ខែ${khmerDate.monthName}`); 
// Output: 14កើត ខែចេត្រ

// Check if a date is a public holiday
const isHoliday = calendar.isHoliday(new Date('2026-04-14'));
console.log(isHoliday); // true (Khmer New Year Day 1)

// Generate iCal (.ics) feed
const ics = calendar.generateICalFeed(2026);

Check it out on npm or GitHub. Feedback and contributions are welcome! 🙌

I built a Khmer Hybrid Calendar package for JavaScript/TypeScript

Heng LOEM — Fri, 17 Jul 2026 03:10:41 +0000

Hey everyone!

I just released khmer-hybrid-calendar – a library that combines Gregorian and Khmer lunar calendars in one easy-to-use package.

Why I built it:

The Khmer calendar is an important part of Cambodian culture, used to determine holidays, religious observances, and traditional events. However, there weren't many modern, well-maintained libraries for developers to integrate this functionality into their applications. I created this to bridge that gap.

Key features:

✅ Accurate Khmer lunar date conversion with moon phase emojis
✅ Complete list of Cambodian national holidays and Buddhist observances
✅ Support for Chinese lunar festivals (New Year, Mid-Autumn, etc.)
✅ iCal feed generation for any year
✅ Full TypeScript support with bundled declarations
✅ Works in Node.js, browser, and React/Next.js applications

Example use:

typescript

import { KhmerCalendar } from 'khmer-hybrid-calendar';

const calendar = new KhmerCalendar();
const khmerDate = calendar.gregorianToKhmer(2026, 4, 13);
console.log(khmerDate.lunarDay); // "១៥កើត"

I'd love to hear your feedback, ideas, or any questions you have!
