Tarikh: Shamsi B Miladi

For converting Miladi to Shamsi, you do the opposite:

| Feature | Tarikh Shamsi (Solar Hijri) | Tarikh Miladi (Gregorian) | | :--- | :--- | :--- | | Basis | Solar (Earth around Sun) | Solar (with leap year rules) | | Year 1 | Hegira (622 CE) | Birth of Jesus (1 CE) | | Start Month | Farvardin (March 20/21) | January 1 | | Used In | Iran, Afghanistan | Most countries worldwide | | Conversion Formula | Miladi = Shamsi + 621/622 | Shamsi = Miladi - 621/622 |

Final Tip: For precise conversion—especially for legal deadlines, birthdays, or historical dates—always use a verified online calendar converter or a dedicated app, as leap year variations can cause a one-day shift. However, for day-to-day reference, adding 621 to the Shamsi year (after spring) is a reliable and easy method.

The conversion from Tarikh Shamsi (Solar Hijri) to Miladi (Gregorian) is a common need for scheduling, official documentation, and history. Because the Solar Hijri year usually begins on the vernal equinox (around March 21), the relationship between the two calendars shifts slightly depending on whether the date falls before or after the Iranian New Year (Nowruz). 1. General Conversion Logic

To convert a Solar Hijri (SH) year to a Gregorian (AD) year, use these simple rules of thumb:

For the first 9 months of the SH year (Farvardin to Azar):Add 621 years to the Solar year.Example: 1403 SH + 621 = 2024 AD.

For the last 3 months of the SH year (Dey to Esfand):Add 622 years to the Solar year.Example: 1403 SH + 622 = 2025 AD. 2. Month Equivalencies

While the exact start days can vary by one day due to leap years, the general alignment is as follows: Solar Hijri Month Approximate Gregorian Start Farvardin Ordibehesht Khordad Tir Mordad Shahrivar Mehr September 23 Aban October 23 Azar November 22 Dey December 22 Bahman January 21 Esfand February 20 3. Key Differences Between the Calendars

Year Zero: The Solar Hijri calendar begins with the Hijra (migration) of Prophet Muhammad in 622 AD.

Accuracy: The Solar Hijri calendar is an astronomical calendar, meaning it is tied to the actual movement of the earth around the sun, making it one of the most accurate seasonal calendars in the world.

Leap Years: Both calendars use leap years, but the Solar Hijri leap year occurs every 4 or 5 years based on complex astronomical observations, whereas the Gregorian calendar follows a fixed mathematical rule (every 4 years, with century exceptions). 4. How to Convert Specific Dates

If you need an exact date (e.g., 15 Mehr 1350), it is best to use a digital converter to account for leap year shifts. Popular tools include: Time.ir: The standard reference for Iranian time and dates.

Calendar.az: A common tool for Persian and Gregorian conversions.

This report examines the Solar Hijri calendar (Tarikh-e Hijri Shamsi), the official timekeeping system of Iran and Afghanistan, and its conversion to the Gregorian calendar (Tarikh-e Miladi). Overview of the Solar Hijri Calendar

The Solar Hijri calendar is a solar-based system that is widely considered one of the most accurate in the world due to its reliance on astronomical observations rather than fixed rules.

Starting Point (Epoch): Like the Lunar Hijri calendar, it starts from the year of the Prophet Muhammad's migration (Hijrah) in 622 CE.

New Year (Nowruz): The year begins at the exact moment of the Vernal Equinox (the start of spring in the Northern Hemisphere), typically on March 21.

Accuracy: It has an error of only one day in about 110,000 years, making it more precise than the Gregorian calendar, which drifts by one day every 3,226 to 3,333 years. Calendar Structure

The year is divided into 12 months, with lengths determined by the Earth's orbit: Month Order Persian Name Month Length Gregorian Equivalent Farvardin to Shahrivar 31 days each March – September Mehr to Bahman 30 days each September – February 29 days (30 in leap years) February – March Conversion Methods Converting dates from the Tarikh Shamsi

Leap Year Rule: Leap years occur every 4 or 5 years. This is typically managed through a 33-year cycle (8 leap years) or, more rarely, a 29-year cycle. Quick Conversion Guide

Because the Solar Hijri year begins in March, a single Shamsi year spans parts of two Miladi years. Year Conversion Formula:

For dates before the start of the next Miladi year (Jan 1): Miladi Year = Shamsi Year + 621

For dates after the start of the next Miladi year: Miladi Year = Shamsi Year + 622

Current Comparison (Example): As of April 2026, the current year is 1405 SH. Practical Tools for Conversion

For precise day-to-day conversion, several digital tools and methods are available:

Even experts make mistakes. Watch out for:

If you need bulk conversion, Excel can handle Tarikh Shamsi b Miladi using a custom VBA script or by leveraging the fact that the Shamsi epoch (1 Farvardin 1) = March 19, 622 CE (Julian).

Better yet, use:

=DATE(ShamsiYear+621,3,21) + (ShamsiMonth-1)*30.5 + ShamsiDay - 1

(Approximate – not precise for month boundaries.)

Miladi Year = Shamsi Year + 621 (for Jan–Mar dates)
Miladi Year = Shamsi Year + 622 (for Apr–Dec dates)

Why? Because the Shamsi new year starts around March 20–21.
