Tarikh Shamsi vs. Tarikh Miladi: Understanding the Difference and Conversion

The terms Tarikh Shamsi (Solar Hijri) and Tarikh Miladi (Gregorian) refer to two of the most widely used calendar systems in the world today. While the Gregorian calendar is the international standard for civil use, the Solar Hijri calendar remains the official calendar in Iran and Afghanistan. tarikh shamsi b miladi

Understanding the history, structure, and conversion methods between these two is essential for historical research, cultural understanding, and administrative purposes.

The Basic Calculation

To convert a Shamsi year to a Miladi year, you generally add 621 or 622. Understanding Tarikh Shamsi and Tarikh Miladi: A Guide

The Formula:

1. If the Shamsi date falls in the first 9 months (Farvardin to Azar): Add 621.
2. If the Shamsi date falls in the last 3 months (Dey to Esfand): Add 622.

Example 1:

• Date: 15 Farvardin 1403 (Shamsi).
• Since Farvardin is the first month, we add 621 to 1403.
• Miladi Date: April 4, 2024.

Example 2:

• Date: 15 Dey 1403 (Shamsi).
• Since Dey is the 10th month, we add 622 to 1403.
• Miladi Date: January 5, 2025.

(Note: Manual calculation can be tricky regarding the exact day due to the difference in month lengths. It is always best to use a digital converter for precise dates.) 🧠 Fun Facts & Tricks

• Leap years in Shamsi are more astronomically precise than Gregorian (based on equinox observation).
• Year 1400 Shamsi began on March 21, 2021 — many Persians celebrated the “new century” with massive festivals.
• In Afghanistan, the Solar Hijri calendar uses Arabic month names (Hamal, Sawr, etc.) but same system.
• Microsoft Excel has no native Shamsi date system — you need custom add-ins.
