Tarikh Shamsi vs Miladi: Understanding the Differences and Conversions
The solar calendar, also known as the Tarikh Shamsi or Persian calendar, and the Gregorian calendar, commonly referred to as the Miladi calendar, are two widely used calendar systems across the world. While the Miladi calendar is the most widely used internationally, the Tarikh Shamsi has significant cultural and historical importance in countries like Iran, Afghanistan, and Tajikistan. This article aims to explore the origins, differences, and conversion methods between these two calendar systems.
Origins of Tarikh Shamsi (Persian Calendar)
The Tarikh Shamsi, or Persian calendar, has its roots in ancient Persia (modern-day Iran). It is a solar calendar that was introduced in 1079 CE by the Seljuk Sultan Jalaluddin Malikshah I. This calendar is based on the solar year, with the beginning of the new year (Nowruz) marking the spring equinox. The Tarikh Shamsi consists of 12 months, with the months being: Farvardin, Ordibehesht, Khordad, Tir, Mordad, Shahrivar, Mehr, Aban, Azar, Dey, Bahman, and Esfand.
Origins of Miladi (Gregorian Calendar)
The Miladi calendar, also known as the Gregorian calendar, was introduced by Pope Gregory XIII in 1582 CE. It is a solar calendar that is based on a 365-day year, with an extra day added every four years (leap year). The Miladi calendar is the most widely used calendar internationally and is used as the global standard for business, travel, and communication.
Key Differences between Tarikh Shamsi and Miladi Calendars
The main differences between the Tarikh Shamsi and Miladi calendars are:
Converting between Tarikh Shamsi and Miladi Calendars
Converting between the two calendars can be done using the following methods:
Miladi Year = Tarikh Shamsi Year + 621 Miladi Month = Tarikh Shamsi Month - 3 (or add 9 if the Tarikh Shamsi month is less than 7)
For example, to convert the Tarikh Shamsi date 1399-01-01 (March 20, 2020) to a Miladi date:
Miladi Year = 1399 + 621 = 2020 Miladi Month = 1 - 3 = March (or add 9: 1 + 9 = 10, which corresponds to October, but this is incorrect)
The correct conversion is: 1399-01-01 (Tarikh Shamsi) = March 20, 2020 (Miladi)
Conclusion
The Tarikh Shamsi and Miladi calendars have distinct differences in their origins, structures, and conversion methods. While the Miladi calendar is widely used internationally, the Tarikh Shamsi calendar holds significant cultural and historical importance in certain regions. Understanding the differences and conversion methods between these two calendars can facilitate communication, trade, and cultural exchange between communities that use different calendar systems.

Title: Understanding the Difference: Tarikh Shamsi vs Miladi
Introduction
In our daily lives, we often take for granted the way we measure time. We wake up every morning, check our clocks, and plan our days accordingly. But have you ever stopped to think about the calendar system we use? In many parts of the world, especially in Iran and Afghanistan, there are two widely used calendar systems: Tarikh Shamsi (Persian Solar Calendar) and Miladi (Gregorian Calendar). In this blog post, we'll explore the differences between these two calendars and their significance.
What is Tarikh Shamsi (Persian Solar Calendar)?
The Tarikh Shamsi, also known as the Persian Solar Calendar, is a solar calendar used in Iran, Afghanistan, and Tajikistan. It is based on the solar year, which is the time it takes the Earth to orbit the sun. This calendar was introduced in 1925 and is a modified version of the ancient Persian calendar.
The Tarikh Shamsi has 12 months, with each month beginning on the day of the equinox or the solstice. The months are:
What is Miladi (Gregorian Calendar)?
The Miladi calendar, also known as the Gregorian Calendar, is the most widely used calendar system in the world. It was introduced by Pope Gregory XIII in 1582 and is a solar calendar that is based on the Earth's orbit around the sun.
The Miladi calendar has 12 months, with each month having a specific number of days:

Conclusion
In conclusion, the Tarikh Shamsi and Miladi calendars are two distinct calendar systems used in different parts of the world. While the Miladi calendar is widely used globally, the Tarikh Shamsi calendar holds significant cultural and historical importance in Iran, Afghanistan, and Tajikistan. Understanding the differences between these calendars can help us appreciate the diversity of human experience and cultural expression.
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. Tarikh Shamsi vs Miladi: Understanding the Differences and
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.
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.
There are dozens of practical reasons why you might need to perform a Tarikh Shamsi b Miladi conversion:
In many parts of the world, especially in Iran, Afghanistan, and among Kurdish communities, two calendars are commonly used side-by-side: Tarikh Shamsi (the Solar Hijri calendar) and Tarikh Miladi (the Gregorian calendar). Knowing the difference and how to convert between them is essential for daily life, business, travel, and historical research.
The fundamental difference in the year count stems from the starting point:
Add 621 from Nowruz to the end of autumn; add 622 from the start of winter until Nowruz.
Converting a Solar Hijri (Shamsi) date to a Gregorian (Miladi) date involves transitioning between two solar-based systems that use different starting points (epochs) and month structures. Understanding the Two Systems
Solar Hijri (Shamsi): Currently the official civil calendar in Iran. It begins each year on the vernal equinox (Nowruz), typically around March 21. It counts years from the Prophet Muhammad's migration (Hijrah) in 622 CE.
Gregorian (Miladi): The internationally used civil calendar. It also follows the solar cycle but starts its year on January 1 and counts from the birth of Jesus Christ (Anno Domini). How to Convert Shamsi to Miladi
Because both calendars follow the sun's orbit, their year lengths are identical (365 or 366 days), making conversion more consistent than lunar systems.
Determine the Year Difference: Generally, adding 621 or 622 years to a Shamsi year provides the Miladi equivalent. Start of the Year : The Tarikh Shamsi
Add 621 years: If the Shamsi date falls between January 1 and the start of the Persian New Year (around March 20/21).
Add 622 years: If the Shamsi date falls after the Persian New Year (after March 21) through December 31. Specific Example: To convert the Shamsi year 1403: Dates before Nowruz (Spring): Dates after Nowruz (Spring): Month Correlation
The first six months of the Shamsi calendar have 31 days, and the next five have 30 days. Farvardin 1 (Nowruz): Typically corresponds to March 21. Tir 1: Typically corresponds to June 21 (Summer Solstice).
Mehr 1: Typically corresponds to September 23 (Autumn Equinox).
Dey 1: Typically corresponds to December 22 (Winter Solstice). Tools for Precise Conversion
For exact day-to-day accuracy, especially during leap years, it is recommended to use an Iranian Date Converter or dedicated mobile apps like the Date Converter.
The phrase tarikh shamsi b miladi refers to the conversion of dates from the Persian Solar Hijri (Shamsi) calendar to the Western Gregorian (Miladi) calendar. Understanding how these two systems interact is essential for anyone dealing with Iranian or Afghan history, business, or culture. The Two Calendar Systems
Solar Hijri (Shamsi): This is the official calendar of Iran and Afghanistan. It is a solar calendar based on the Earth's orbit around the sun. The year begins at the exact moment of the vernal equinox (Nowruz), typically occurring between March 19 and March 21.
Gregorian (Miladi): Used internationally for civil purposes, this calendar counts years from the assumed birth of Jesus Christ. It is also solar-based but follows fixed rules for month lengths and leap years, unlike the Shamsi calendar which relies on astronomical observations. How to Convert: A Simple Formula
To convert a Solar Hijri year to a Gregorian year, you generally add 621 or 622 years, depending on the month.
Between Nowruz (March 21) and December 31: Add 621 years to the Shamsi year.
Between January 1 and Nowruz (March 20): Add 622 years to the Shamsi year.
Example: To find the Gregorian equivalent for the year 1404 SH: If the date is after Nowruz (Spring), If the date is before Nowruz (Winter), Monthly Differences
The Solar Hijri year consists of 12 months, with the first six months always having 31 days and the next five having 30 days. The final month, Esfand, has 29 days in a common year and 30 in a leap year. This rigid structure differs from the Gregorian system, where months like February, April, and June vary more widely in length. Accuracy and Leap Years
The Solar Hijri calendar is considered one of the world’s most accurate because its start date is determined by astronomical measurement of the sun entering the Northern Hemisphere. While the Gregorian calendar uses a fixed rule (adding a leap day every four years, except for most century years), the Shamsi system uses a complex 33-year cycle to determine leap years, ensuring it stays perfectly aligned with the seasons.
