How do Solar Hijri and Gregorian years differ?
The Solar Hijri calendar counts from the Hijrah with a solar year: the first 6 months have 31 days, the next 5 have 30 days, and Esfand has 29 or 30. The Gregorian calendar counts from the birth of Christ, with 28–31-day months and a four-year leap rule (with century exceptions).
Because both are solar but start at different points — the Hijri year begins around 20–21 March while the Gregorian year starts on 1 January — mental conversion is error-prone.
How does the conversion work?
Conversion is an exact calculation, not an estimate: the Solar Hijri date is mapped to a continuous day count and read back in the Gregorian calendar. The result is unique and independent of time zones or seasons.
The output shows only two rows: weekday and the Gregorian equivalent (result). The “Copy result” button copies the Gregorian date with its weekday for direct use in forms and messages.
Leap years and 30-day Esfand
A leap Solar Hijri year has 366 days with a 30-day Esfand. Example: 30 Esfand 1403 equals Thursday, 20 March 2025. Years 1404 and 1405 are not leap years (365 days, 29-day Esfand).
Entering a day that does not exist in that month (for example 30 Esfand in a non-leap year) shows an “Invalid Solar Hijri date” message and no conversion is performed.
Input range and limits
The Solar Hijri year range of this tool is 1200–1500; output in this range matches Iran’s official calendar. The Gregorian and Hijri ranges are documented on the Gregorian to Solar Hijri and Hijri to Solar Hijri pages.
For today’s date see the Iran calendar home, and for the full year the 1405 calendar.
Practical uses
📋 International forms
Foreign forms use Gregorian dates; take the exact Gregorian equivalent of a Solar Hijri date from this tool and paste it with the copy button.
⏰ Deadlines and contracts
Payment due dates and contract ends announced by foreign parties are usually Gregorian; exact conversion prevents one-day deadline slips.
📅 Two-calendar scheduling
When your team works on the Gregorian calendar, record both dates in your notes so planning stays unambiguous.
Tips and common traps
💡 Do not forget leap years
30 Esfand exists only in leap years; the most recent leap year was 1403, and 1404 and 1405 are not leap years.
📍 1 Farvardin has no fixed Gregorian date
Nowruz usually falls on 20 or 21 March; leave the conversion to calculation so the result is not off by a day.
🗓️ Weekday as a quick check
A date and its equivalent point to the same day, so their weekdays match — a fast way to sanity-check a conversion.

Frequently asked questions about Solar Hijri to Gregorian
How do I convert a Solar Hijri date to Gregorian?
Enter the Solar Hijri year (for example 1405), pick the month from the list, enter the day and press “Convert to Gregorian”. The result appears instantly with the weekday and Gregorian equivalent; for example, 1 Farvardin 1405 equals Saturday, 21 March 2026.
Is Solar Hijri to Gregorian conversion exact?
Yes; conversion is an exact day-count calculation and does not depend on time or time zone. Only the Hijri equivalent may differ by one day, because it is computed on the Umm al-Qura basis.
What is the Gregorian date of 1 Farvardin?
1 Farvardin is usually 20 or 21 March. For instance, 1 Farvardin 1405 is 21 March 2026 and 1 Farvardin 1400 was 21 March 2021; use this tool for any other year.
What happens with empty or invalid input?
An error message is shown and no conversion is performed; for example, 30 Esfand 1404 is invalid because 1404 is not a leap year and its Esfand has 29 days.
Why is the weekday shown too?
Because a Gregorian date and its Solar Hijri equivalent point to the same day, their weekdays are identical — so the weekday is a quick correctness check (example: 1 Farvardin 1405 = Saturday = 21 March 2026).
Data source and limits
Nothing on this page is hand-written or estimated: Gregorian equivalents, weekdays and Hijri equivalents are all computed with this site’s calendar engine (assets/js/date-core.js). Hijri equivalents use the Umm al-Qura calendar and may differ by up to one day from moon-sighting announcements.
