When Is Persian New Year in 2025?

Persian New Year, also known as Nowruz, will begin on Thursday, March 20, 2025, precisely at 5:01 AM UTC, coinciding with the astronomical vernal equinox. This moment marks the exact time when day and night are nearly equal in length, symbolizing balance and renewal—a core theme of when Persian New Year is observed each year. Unlike fixed-date holidays, Nowruz follows the solar calendar and always aligns with the first day of spring in the Northern Hemisphere, typically falling on March 20 or 21. The celebration spans 13 days and is observed by millions across Iran, Central Asia, the Caucasus, the Middle East, and diaspora communities worldwide.

What Is Nowruz?

Nowruz, meaning 'new day' in Persian, is a festival that heralds the beginning of the Iranian New Year. Rooted in Zoroastrianism, one of the world’s oldest monotheistic religions, Nowruz has been celebrated for over 3,000 years. It transcends religious boundaries and is embraced by Muslims, Christians, Jews, Baha’is, and secular populations alike. UNESCO recognized Nowruz as an Intangible Cultural Heritage of Humanity in 2009, underscoring its cultural significance and enduring legacy.

The holiday is not tied to any single faith but rather to nature, rebirth, and hope. Families gather to celebrate the triumph of light over darkness, life over stagnation, and harmony over chaos. The timing of when Persian New Year occurs each year depends entirely on precise astronomical calculations, ensuring that the new year begins exactly when the sun crosses the celestial equator.

Historical Origins of Nowruz

The origins of Nowruz trace back to ancient Persia during the Achaemenid Empire (c. 550–330 BCE). Historical records indicate that kings held grand Nowruz celebrations at Persepolis, where dignitaries from across the empire brought gifts. The festival was deeply connected to Zoroastrian cosmology, emphasizing fire, water, earth, and air as sacred elements.

Despite the Arab conquest of Persia in the 7th century and the spread of Islam, Nowruz endured due to its cultural rather than religious nature. Islamic rulers, including those from the Samanid and Safavid dynasties, preserved and even expanded Nowruz traditions. Over centuries, it absorbed regional customs while maintaining its central symbolism of renewal and unity.

How the Date of Persian New Year Is Determined

Unlike Gregorian calendar-based holidays, the date of Persian New Year is determined astronomically. The event is set by the instant of the vernal equinox—the moment the Sun appears directly above the Earth's equator, moving northward. This calculation varies slightly each year depending on Earth’s orbit.

In Iran, the official timekeeping authority uses the observatory in Tehran to determine the exact second Nowruz begins. For global observers, Coordinated Universal Time (UTC) is often used as a reference point. In 2025, this moment falls on March 20 at 5:01 AM UTC. Local times vary:

Location	Local Time (March 20, 2025)
Tehran, Iran	8:31 AM
Dubai, UAE	9:01 AM
London, UK	5:01 AM
New York, USA	12:01 AM (midnight)
Toronto, Canada	12:01 AM
Sydney, Australia	4:01 PM

Because the equinox can occur before or after midnight local time, some regions may observe Nowruz on March 21. However, most countries—including Iran—officially recognize March 20 as the public holiday.

Traditional Customs and Rituals

Preparations for when Persian New Year is celebrated begin weeks in advance. One of the most iconic traditions is khaneh tekani, or 'shaking the house,' a thorough spring cleaning meant to purge negativity and welcome positivity. Homes are scrubbed, carpets beaten, and old items discarded or donated.

The centerpiece of Nowruz is the Haft-Seen table—a display of seven symbolic items, each starting with the Persian letter 'seen' (س). These include:

• Sabzeh (wheat or lentil sprouts): Growth and renewal
• Samanu (sweet wheat pudding): Affluence and fertility
• Senjed (dried lotus fruit): Love and wisdom
• Seer (garlic): Health and medicine
• Seeb (apple): Beauty and health
• Sumaq (sumac berries): The color of sunrise, victory over darkness
• Serkeh (vinegar): Patience and age

Additional items often placed on the Haft-Seen include a mirror (reflection), candles (light and happiness), goldfish in a bowl (life), painted eggs (fertility), and a copy of the Quran or poetry by Hafez. Families gather around the Haft-Seen at the exact moment Nowruz begins, exchanging wishes and sometimes reading poetry.

Regional Variations Across Cultures

While centered in Iran, Nowruz is celebrated across diverse cultures under different names and with unique customs. In Afghanistan, it’s called Nawroz; in Kurdish regions, Newroz; in Central Asia, Navruz. Despite variations, the underlying themes remain consistent: renewal, family, and nature.

• Azerbaijan: People jump over bonfires during Chaharshanbe Suri, a pre-Nowruz fire-jumping ritual believed to cleanse the soul.
• Kurdistan: Fire plays a central role, with large public bonfires and dancing. Women wear traditional colorful attire.
• Tajikistan: Families prepare sumalak, a thick sweet paste made from germinated wheat, cooked overnight in communal pots.
• Albania and the Balkans: Some communities observe Sultan Nevruz, honoring a Bektashi saint associated with springtime.

Diaspora communities in the United States, Canada, Germany, and Sweden have adapted Nowruz to urban settings, hosting public festivals, music performances, and educational events to preserve cultural identity.

Common Misconceptions About Persian New Year

Several misunderstandings surround when and how Persian New Year is observed:

1. Misconception: Nowruz is a religious Islamic holiday.
   Reality: It predates Islam and is primarily cultural and secular, though many Muslims observe it.
2. Misconception: Nowruz always starts on March 21.
   Reality: It begins at the exact moment of the equinox, which can fall on March 20 or 21 depending on the year and time zone.
3. Misconception: Only Iranians celebrate Nowruz.

How to Prepare for Nowruz in 2025

If you're planning to celebrate the Persian New Year in 2025, here are practical steps:

• Set up your Haft-Seen: Begin growing sabzeh (sprouts) at least three weeks before March 20. Use a decorative tray and arrange all seven 'S' items thoughtfully.
• Clean your home: Dedicate a weekend to deep cleaning. Involve family members to make it a bonding activity.
• Buy new clothes: Wearing new or clean garments symbolizes a fresh start.
• Plan visits: The first 13 days involve visiting relatives, starting with elders. Host guests on specific days based on tradition.
• Prepare traditional foods: Cook dishes like sabzi polo ba mahi (herb rice with fish), kuku sabzi (herb frittata), and ash reshteh (noodle soup).

The Thirteenth Day: Sizdah Bedar

The final day of Nowruz, known as Sizdah Bedar (meaning 'getting rid of the thirteenth'), falls on April 1, 2025. It’s considered unlucky to stay indoors, so families picnic outdoors, throw the sabzeh into flowing water (symbolizing letting go of misfortunes), and enjoy games and music. This day emphasizes nature, humor, and social connection.

Modern Challenges and Global Recognition

In recent decades, political tensions in certain regions have led to restrictions on Nowruz celebrations. Nevertheless, its resilience continues. In 2010, the United Nations officially recognized March 21 as the International Day of Nowruz, affirming its role in promoting peace and intercultural dialogue.

Cities like Los Angeles, Toronto, and London now host large-scale Nowruz parades and cultural exhibitions. Google has marked the occasion with Doodles since 2009, increasing global awareness of when Persian New Year takes place and what it represents.
