A Comprehensive Guide with Reference Tables

Introduction

The Islamic (Hijri) and Desi (Bikrami) calendars are widely used in Muslim-majority regions, particularly in South Asia. While the Hijri calendar is lunar-based and used for religious events, the Desi calendar is solar-based and traditionally used for agricultural and cultural purposes. Combining both into a dual-calendar system provides a seamless way to track dates for religious, cultural, and daily activities.

This article explores the structure, conversion methods, and benefits of using a dual Islamic & Desi calendar system, complete with reference tables for easy date lookup.

Why Use a Dual Islamic & Desi Calendar?

1. Religious & Cultural Synchronization – Track both Islamic events (Ramadan, Eid) and Desi festivals (Baisakhi, Lohri).
2. Agricultural Planning – Farmers can align crop cycles with the solar-based Desi months.
3. Historical & Traditional Relevance – Many South Asian communities still follow the Desi calendar for cultural events.
4. Global & Local Compatibility – Works alongside the Gregorian calendar for international scheduling.

How to Convert Between Hijri & Desi Dates

Since the Hijri calendar is lunar and the Desi calendar is solar, direct conversion requires reference points. Below is a simplified conversion method:

Example Conversion (2025)

Gregorian Date	Hijri Date	Desi Date
August 15, 2025	22 Safar 1447 AH	1 Bhadon 2082
March 14, 2025	14 Sha’ban 1446 AH	1 Chet 2082

Mathematical Approximation:

• Hijri to Gregorian:
• Each Hijri year ≈ 354 days (11 days shorter than Gregorian).
• Example: 1447 AH ≈ 2025 CE (but shifts yearly).
• Desi to Gregorian:
• Desi year = Gregorian year + 57 (e.g., 2025 CE = 2082 Desi).
• Fixed start dates (e.g., Chet starts on March 14).
