Persian Calendar 1405 (2026–2027): Key Dates, Holidays & Printable Guide

What is the Persian (Solar Hijri) calendar?

The Persian calendar—often called the Solar Hijri calendar (in Persian: تقویم هجری شمسی)—is the official calendar used in Iran and is widely used culturally by Persian-speaking communities around the world. It’s “Hijri” because the year numbering historically references the Hijra (migration of the Prophet Muhammad), but it’s solar because the calendar tracks the Earth’s orbit around the sun rather than lunar cycles. That one fact explains why it feels so practical: months stay aligned with seasons in a stable way, so spring holidays remain spring holidays, and winter nights remain winter nights.

In everyday life, the Persian calendar is more than a date system—it’s a rhythm. It’s how people structure Nowruz preparations, spring cleaning, family visits, and seasonal foods; it’s how businesses and schools plan, and it’s also how many diaspora families keep a cultural anchor even when they live under a different official calendar. If you’ve ever watched someone reference both “March” and “Farvardin” in one sentence, you’ve already seen how it functions as cultural memory.

When does Persian year 1405 start and end in 2026–2027?

Persian year 1405 begins around the March equinox of 2026 and runs to the March equinox of 2027. In most common conversions, you’ll see it described like this:

• Start (approx.): March 21, 2026
• End (approx.): March 20, 2027

Why “approximate”? Because the Persian New Year (Nowruz) is tied to the exact astronomical equinox moment (تحویل سال). Depending on the year, the equinox can occur at a time that causes the civil calendar boundary to fall a day earlier or later in some contexts. For most planning—blog content, gift guides, shopping seasons, and cultural education—these boundaries are accurate enough. For legal deadlines, official documents, or flight itineraries, it’s smart to confirm with a reliable converter on the specific date you care about.

Months of 1405 (with approximate Gregorian ranges)

The Persian calendar has 12 months. The first six months are 31 days, the next five are 30 days, and the last month is 29 days (or 30 in leap years). The table below gives you a practical “mental map” of year 1405. Keep in mind these ranges can shift by about a day from year to year.

If you’re building content for SEO or product drops, this table is surprisingly useful. It tells you when “Nowruz prep” actually starts in the cultural calendar (Esfand), when autumn aesthetics begin (Mehr), and why Yalda content tends to live in Azar. When your site aligns with this rhythm, your content feels “native” to the audience—even if they’re reading it in English.

How the Persian calendar works (why it’s so accurate)

The Persian calendar’s reputation for accuracy comes from its relationship to the solar year. Instead of drifting through seasons (a common issue in purely lunar calendars), it anchors the year to the sun’s cycle. The beginning of the year is connected to the spring equinox, which is why Nowruz is not just “a date” but a seasonal event. Over long periods, that solar anchoring keeps months aligned with climate patterns, agricultural cycles, and the emotional feel of the year—spring renewal, summer intensity, autumn reflection, winter endurance.

The other piece is month structure. The Persian months are designed to match the reality of the solar year: longer months in the spring and summer, then slightly shorter as the year progresses. The final month (Esfand) is the flexible one, sometimes gaining an extra day in leap years. That leap adjustment is the quiet hero that keeps the calendar stable. For you as a shop owner and content publisher, the practical result is this: seasonal content stays seasonally correct, year after year, without drifting in a way that confuses customers.

Key dates & holidays in year 1405

Persian cultural holidays often have two layers: the fixed “calendar day” layer (for example, 1 Farvardin is always Nowruz) and the lived “social season” layer (for example, the whole final stretch of Esfand feels like Nowruz preparation). Below are the most useful anchors for planning and content. Where a Gregorian date could shift slightly year-to-year, I describe it as a window rather than pretending it’s always identical.

Nowruz (Persian New Year) — 1 Farvardin 1405

Nowruz begins at the moment of the spring equinox (تحویل سال) and marks the first day of Farvardin. In 2026, that falls around March 20–21 depending on the exact equinox time. In practical terms, if you are planning content or product promotions, your best timing is not the day of Nowruz—it’s the runway. The cultural build-up happens throughout Esfand, when people clean, shop, refresh wardrobes, replace household items, and buy gifts that feel symbolic rather than random.

Chaharshanbe Suri — late Esfand 1405

Chaharshanbe Suri is the fire-jumping festival held on the eve of the last Wednesday before Nowruz. Because it’s tied to the week structure rather than a fixed Persian date in the way Nowruz is felt, it shifts each year in Gregorian terms. For content strategy, treat it as a late-Esfand moment: themes of purification, letting go, courage, and “burning away” the heaviness of the year. It’s a powerful cultural story that can link naturally to symbolic gifts without sounding forced.

Sizdah Bedar — 13 Farvardin 1405

Sizdah Bedar (the 13th day of Nowruz season) is the outdoor day—picnics, nature, fresh air, and the final “release” of the Nowruz cycle. In Gregorian terms, it usually lands around early April. This is a good moment for lighter content: spring outdoors, family traditions, simple gift items (postcards, small charms, stationery), and “new year energy” without heavy explanations.

Yalda Night — late Azar 1405

Yalda is the longest night of the year (winter solstice), celebrated with pomegranates, nuts, poetry, and the warmth of gathering. In Gregorian terms, it’s around December 21, which aligns with late Azar / the Azar-to-Dey boundary. If your site sells Persian-inspired gifts, Yalda is an underrated opportunity because it feels intimate and cultural while also fitting naturally into the broader holiday shopping season in many countries.

Seasonal anchor months you can plan around

If you want a publisher’s cheat code for year 1405, here it is: Esfand = Nowruz prep, Farvardin = renewal + visiting, Mehr = autumn cultural mood, and Azar = Yalda season. You don’t need a calendar full of micro-events to rank—Google and readers both respond better when one page clearly owns a topic and your internal links make the site feel organized.

How to convert dates (without headaches)

Converting between Persian and Gregorian dates is easier when you stop trying to “calculate” and start using stable anchors. The number-one anchor is Nowruz: Persian years roll over around March 20–21. So if you see a Persian date in Farvardin, you’re usually in late March or April. If you see Mehr, you’re in early autumn. If you see Dey, you’re in winter. This mental map gets you 80% of the way in daily life, especially for planning content and gifts.

For exact conversions, use a reputable converter and confirm the time zone if the date sits near a boundary (like Nowruz). The tricky cases are usually the first and last days of the year, not the middle months. If you want your blog to be trustworthy, say the truth: “around March 21” is better than confidently stating an exact date that can shift. Readers respect accuracy more than false precision.

Quick examples you can understand instantly

• 1 Farvardin 1405 ≈ March 20–21, 2026 (Nowruz)
• 13 Farvardin 1405 ≈ early April 2026 (Sizdah Bedar)
• Azar 1405 ≈ late November to late December 2026 (Yalda season)
• Esfand 1405 ≈ late February to mid/late March 2027 (Nowruz prep)

Using the Persian calendar in the diaspora

In the diaspora, the Persian calendar often becomes a “second calendar”—not official, but emotionally official. Families use it to remember birthdays, plan gatherings, and keep cultural timing intact even when work and school run on the Gregorian system. That dual-calendar life is exactly why a clear 1405 guide matters: it reduces friction. It helps someone plan a Nowruz gift early, understand why “Esfand” is a whole mood, and stop feeling lost when elders reference dates that don’t match the phone’s default calendar.

From a business perspective, this is also where you can earn trust. Most stores try to sell “Persian items” without organizing information. When your content explains the calendar cleanly, you’re not just attracting traffic—you’re demonstrating that your store actually understands the culture. That kind of authority turns into bookmarks, shares, and repeat visitors, which is exactly what keeps a young website “floating higher.”

Desk calendar tip: making 1405 easy to live with

If you regularly switch between Persian and Gregorian dates, a desk calendar can remove the daily mental load—especially around Nowruz when boundaries matter. The best Persian calendars do two things well: they keep the Persian months readable (so you actually use them), and they make the Gregorian alignment obvious (so you can plan work schedules, school deadlines, and travel).

If you offer a 1405 desk calendar on your store, link it here with a simple, non-pushy line: “If you want a 1405 calendar you can keep on your desk all year, here’s ours.” That’s it. Let the content do the selling.

FAQ

What Gregorian year is 1405 in the Persian calendar?

Persian year 1405 overlaps two Gregorian years. It starts around late March 2026 and ends around late March 2027. The exact boundary depends on the equinox moment, but for most everyday use, “2026–2027” is the correct answer.

Is the Persian calendar the same as the Islamic (lunar) calendar?

No. The Persian (Solar Hijri) calendar is solar, meaning months track the seasons. The Islamic Hijri calendar is lunar, meaning months shift across seasons over time. They share historical naming conventions around “Hijri,” but they behave very differently in real life.

Why does Nowruz sometimes show as March 20 and sometimes March 21?

Because Nowruz is tied to the exact astronomical equinox moment. Depending on the year and your time zone, the equinox can occur at a time that places the new year boundary on one day or the next in the civil calendar. This is normal and expected.

What’s the easiest way to use the Persian calendar day-to-day?

Use a reliable converter for exact dates near boundaries (Nowruz/Esfand), and use the month “season map” for everyday understanding. If you regularly plan events, a dual-date Persian desk calendar can make life dramatically easier.
