Q: Is Tarikh Shamsi more accurate than Miladi?
A: Yes, significantly. Shamsi’s drift is near zero; Miladi drifts 1 day per ~3,300 years.
Q: Why is Miladi used everywhere?
A: Colonial history, industrial standardization, and digital compatibility—not because it’s astronomically better.
Q: Can I convert Shamsi to Miladi easily?
A: For rough conversion: add 621 or 622 (e.g., Shamsi year 1403 ≈ Miladi 2024–2025). For exact dates, use online converters or Python’s jdatetime library.
Q: Which is better for programming?
A: Absolutely Miladi. Store dates as UTC Gregorian; convert to Shamsi only for front-end display.
This article was last updated in 2026 — Miladi year 2026 currently corresponds to Shamsi years 1404 (until March 20) and 1405 (starting March 21).
Share this article with anyone debating between Tarikh Shamsi and Tarikh Miladi. Both calendars deserve respect—but now you know which one is “better” for your specific need. tarikh shamsi b miladi better
Whether you are planning an international trip, coordinating a business meeting, or just curious about the history behind our calendars, understanding the switch between (Solar Hijri) and (Gregorian) dates is essential.
Here is a breakdown of why these two systems differ and how to handle them like a pro. 📅 The Core Differences
While both calendars track the sun, they are built on very different historical and astronomical foundations: Shamsi (Solar Hijri):
Based on the solar year and the vernal equinox (first day of Spring/Nowruz). It is used officially in Iran and Afghanistan. Miladi (Gregorian):
The internationally standard calendar used by most of the world for civil and business purposes. 🔄 Quick Conversion Guide Q: Is Tarikh Shamsi more accurate than Miladi
If you are moving between these two systems, keep these general rules in mind: The "Gap": There is a roughly 621-622 year difference
between the two. For example, the Gregorian year 2026 aligns with parts of the Solar Hijri years 1404 and 1405. New Year Start: The Shamsi year begins around March 20th or 21st
. This means the "year" doesn't flip at the same time in both systems. 🛠️ Practical Tools for the Switch
You don't have to do the math by hand! Use these resources to stay accurate:
Simple approximation:
Exact formula (algorithmic):
Example:
1 Farvardin 1405 SH = March 20, 2026 CE (or March 21 depending on equinox).
Common conversion tools:
| Metric | Shamsi | Miladi | |--------|--------|--------| | Year length | ~365.2422 days (matches tropical year precisely via observation) | ~365.2425 days (Gregorian rule) | | Drift over 1000 years | Negligible (observed equinox corrections) | ~0.3 days per 1000 years | | Seasonal alignment | Perfect – New Year always at spring equinox | Drifts ~1 day every 128 years (Gregorian correction minimizes but doesn’t eliminate) |
Verdict: Tarikh Shamsi is astronomically more accurate for seasonal tracking. Miladi is computationally simpler for global standardization. This article was last updated in 2026 —
| Feature | Tarikh Shamsi | Tarikh Miladi | |---------|---------------|----------------| | Year length | 365 or 366 days (solar) | 365 or 366 days (solar) | | Leap year rule | Complex astronomical: based on actual equinox | Simple rule: divisible by 4 except centuries not divisible by 400 | | Month lengths | 6 months of 31 days, 6 of 30 days (last month 29/30) | Irregular: 28–31 days | | New Year | March 20/21 (vernal equinox) | January 1 (no astronomical event) | | Seasonal drift | None – year always starts at spring | Minimal but ~1 day drift per century relative to equinox |
