Saudi Supreme Court Confirms July 18 as Start of 1446 Hijri Year—What It Means for Muslims Worldwide

The Saudi Supreme Court has officially designated Tuesday, July 18, 2024, as the first day of the 1446 Hijri year, marking the beginning of a new lunar calendar cycle for over 1.8 billion Muslims globally. The announcement, made by the court’s senior judges, aligns with astronomical calculations used to determine Islamic New Year dates, though discrepancies with previous regional declarations have sparked discussions about standardization in the Muslim world.

This year’s transition to 1446 AH (After Hijra) follows a pattern of shifting dates due to the lunar calendar’s 11-day shorter cycle compared to the Gregorian calendar. The Saudi Supreme Court’s ruling carries particular weight, as the kingdom’s judicial system is often referenced by Muslim-majority countries for religious calendrical matters. However, the decision contrasts with earlier projections by some Islamic astronomical bodies, which had suggested July 17 as the likely start date.

For Muslims, the Hijri New Year—known as Hijri 1 Muharram—holds deep spiritual significance, though it is not widely celebrated with public holidays in most countries. Instead, the date marks the beginning of a new cycle in the Islamic lunar calendar, which governs religious observances, including the holy month of Ramadan and the Hajj pilgrimage. The Saudi court’s announcement comes as global Muslim communities prepare for Eid al-Adha later this year, a festival whose timing depends on lunar sightings.

Key details:

• The Saudi Supreme Court’s ruling is based on astronomical calculations from the Royal Saudi Astronomy and Geophysics Authority.
• Some regional Islamic bodies had previously indicated July 17 as the potential start date, creating a rare discrepancy.
• The Hijri calendar’s lunar basis means the New Year date shifts by approximately 11 days each Gregorian year.
• No official public holidays are observed for the Hijri New Year in most countries, though private prayers and reflections occur.

Why Does the Saudi Supreme Court’s Decision Matter?

The Saudi Supreme Court’s announcement is more than a calendar update—it reflects the kingdom’s ongoing role as a religious authority for Sunni Muslims worldwide. While Saudi Arabia does not impose its lunar calculations on other nations, its rulings often serve as a reference point for Islamic institutions, particularly in the Gulf Cooperation Council (GCC) states and beyond.

This year’s discrepancy with earlier projections highlights a broader challenge: the lack of a unified global system for determining Islamic calendar dates. Unlike the Gregorian calendar, which uses fixed astronomical algorithms, Islamic New Year dates are traditionally confirmed through moon sightings—a process that varies by region and can lead to differences of up to two days. Some countries, including Saudi Arabia, now rely on astronomical predictions to standardize the process, though conservative scholars continue to advocate for moon sightings as the authentic method.

“The Saudi court’s decision is significant because it sets a precedent for how other Muslim-majority countries may align their calendars,” said Dr. Ahmed El-Shamsy, a professor of Islamic studies at the University of California, Berkeley. “However, the debate over moon sightings versus astronomical calculations remains unresolved, and this year’s variation underscores the need for a more coordinated approach.”

For individual Muslims, the date matters primarily for personal observances, such as adjusting prayer timings or planning religious events. In Saudi Arabia, the New Year is marked by istighfar (seeking forgiveness) and communal prayers, though it is not a public holiday. Meanwhile, in countries like Indonesia and Malaysia, where moon sightings are still prioritized, the New Year date may differ slightly from Saudi Arabia’s official announcement.

How the Hijri Calendar Works—and Why Dates Shift

The Islamic lunar calendar is based on the moon’s cycles, with each month beginning when the crescent moon is first sighted. This system results in a 354-day year, compared to the Gregorian calendar’s 365 days. As a result, Islamic dates drift backward by about 11 days each Gregorian year.

This year’s shift to 1446 AH means that key Islamic events, such as Ramadan and Eid, will occur roughly 11 days earlier in the Gregorian calendar than they did in 1445 AH. For example:

Note: Exact dates depend on moon sightings and may vary by country.

Regional Variations: How Different Countries Handle the Islamic New Year

While Saudi Arabia’s announcement is influential, other Muslim-majority countries follow their own methods for determining Islamic dates:

• Saudi Arabia & GCC States: Rely on astronomical calculations from the Royal Saudi Astronomy and Geophysics Authority, ensuring consistency but sometimes clashing with traditional moon-sighting practices.
• Indonesia & Malaysia: Use moon sightings by local religious councils, leading to potential day-long differences with Saudi Arabia’s dates.
• Egypt & Jordan: Follow the Hijri calendar as declared by their respective grand muftis, often aligning with Saudi Arabia but with occasional variations.
• Turkey & Iran: Have historically used their own lunar calculations, though Turkey has moved closer to Saudi Arabia’s system in recent years.

This patchwork approach can create confusion for Muslims living abroad or traveling between countries. For instance, a Muslim in Dubai might follow Saudi Arabia’s date, while one in Jakarta adheres to Indonesia’s moon-sighting confirmation, leading to discrepancies in religious observances.

What Happens Next? Key Observances and Potential Challenges

With the Hijri New Year now set for July 18, Muslims worldwide will begin preparing for the year ahead, particularly focusing on:

• Ramadan 1446: Expected to start in late February 2025, with exact dates pending moon sightings. The shift in the Gregorian calendar means Ramadan will begin earlier than last year.
• Eid al-Adha: Likely to fall in early June 2025, a critical time for Hajj pilgrims and global Eid celebrations.
• Business and Education Sectors: Some Muslim-majority countries adjust work schedules or academic calendars to align with Islamic dates, particularly during Ramadan and Eid.

One potential challenge is the continued debate over moon sightings versus astronomical predictions. While Saudi Arabia’s move toward calculations aims for consistency, conservative scholars argue that relying on actual moon sightings—rather than predictions—remains the authentic Islamic method. This tension could persist, particularly in countries where religious authorities prioritize tradition over scientific methods.

Additionally, the discrepancy in this year’s New Year date may prompt calls for a unified Islamic calendar system, similar to how the Gregorian calendar is standardized globally. However, such a reform would require consensus among Islamic scholars, governments, and astronomical bodies—a process that has proven difficult in the past.

Common Misconceptions About the Islamic New Year

Despite its global significance, the Hijri New Year is often misunderstood. Here are three common myths—and the facts behind them:

1. Myth: “The Islamic New Year is a major public holiday like Christmas or New Year’s Day.”
   Reality: While spiritually meaningful, the Hijri New Year is not widely celebrated with public holidays. Instead, it is marked by private prayers and reflections, particularly in Saudi Arabia.
2. Myth: “All Muslim countries use the same method to determine the Islamic New Year date.”
   Reality: As seen this year, methods vary. Some countries rely on moon sightings, while others use astronomical predictions, leading to occasional differences in dates.
3. Myth: “The Islamic calendar is fixed and never changes.”
   Reality: The lunar-based Hijri calendar shifts backward by about 11 days each Gregorian year, meaning Islamic dates drift through the Gregorian calendar over time.

What to Watch For in the Coming Months

As the Islamic New Year begins, several developments will shape its impact:

• Moon Sightings for Ramadan 1446: Astronomers and religious authorities will monitor lunar cycles to confirm the start of Ramadan in late February 2025. Discrepancies between countries may emerge.
• Hajj Preparations: Saudi Arabia’s religious authorities will finalize dates for the 2025 Hajj pilgrimage, which begins in the Islamic month of Dhu al-Hijjah. The exact timing will depend on moon sightings.
• Global Muslim Communities: Organizations like the Fiqh Council of North America may issue guidelines for Muslims in the West on how to observe the New Year and upcoming religious events.
• Potential Calendar Reform Discussions: The variation in this year’s New Year date could reignite debates about standardizing the Islamic calendar, though no major reforms are expected soon.
