Determining exactly when was Muhammed born isn't as straightforward as looking at a modern birth certificate. Most historians and Islamic scholars point to the year 570 CE. But honestly, if you dig into the lunar calendars and the oral traditions of 6th-century Arabia, things get a bit more nuanced. It’s a mix of astronomical tracking and deep-seated cultural memory.
He was born in Mecca. A rugged, bustling trade hub.
The traditional date most people cite is the 12th of Rabi' al-Awwal. This falls in the third month of the Islamic calendar. However, because the Islamic calendar is lunar, that date shifts every year relative to the Gregorian calendar. If you're looking for the Western equivalent, it’s generally accepted as April 22, 570 CE.
But wait. There's more to it.
The Year of the Elephant: Why 570 CE Matters
In pre-Islamic Arabia, people didn't use a continuous numbering system for years like we do now. They named years after major events. The year the Prophet was born is famously known as Am al-Fil, or the Year of the Elephant.
Why elephants? Because Abraha, the Yemeni Christian ruler, supposedly marched toward Mecca with an army that included war elephants, intending to destroy the Kaaba. It failed. The event was so seismic that it became the "Year Zero" for that generation.
Does the math actually add up?
Some modern historians, like Lawrence Conrad, have poked at the 570 CE date. They suggest he might have been born a bit earlier, perhaps 567 CE. Why the discrepancy? Because early biographies (Sirah) were written down decades, sometimes over a century, after the events happened. Scholars like Ibn Ishaq and Ibn Hisham did incredible work, but they were working with an oral tradition that prioritized the significance of an event over a precise GPS-stamped timestamp.
Still, for the vast majority of the world's two billion Muslims, 570 CE remains the gold standard.
Dissecting the Day: 12th or 17th of Rabi' al-Awwal?
Here is where it gets interesting. Depending on who you ask, the specific day changes.
Sunni Muslims typically observe the 12th of Rabi' al-Awwal as the Mawlid (the birth anniversary). Meanwhile, most Shia scholars argue for the 17th of Rabi' al-Awwal. It's a five-day gap that has existed for centuries.
Some scholars, like the 13th-century historian Ibn Dihya, noted that even in the early days, there were debates. Some said he was born on the 2nd, others the 8th, or even the 10th.
Does it change the theology? Not really. But it shows that the early community was more focused on his message than his "birthday party." In fact, for the first couple of centuries, there wasn't a massive celebration like we see today. The Mawlid as a major public festival didn't really kick off until the Fatimid Caliphate in Egypt or the Muzaffarids in Iraq much later.
The Monday Connection
One thing everyone seems to agree on is the day of the week.
Muhammed was born on a Monday.

There's a famous Sahih Muslim Hadith where someone asked him why he fasted on Mondays. He replied, "That is the day on which I was born and the day on which I received Revelation."
This is a rare piece of "hard data" in the biographical record. If you track back the calendars—which is a headache because of the way "intercalary months" were used in old Arabia—a Monday in the spring of 570 CE lines up pretty well with the late April date.
The Context of Mecca in 570 CE
To understand when was Muhammed born, you have to understand the world he entered. It wasn't a vacuum. Mecca was a "Haram," a sanctuary.
His father, Abdullah, died before he was even born. His mother, Aminah, was left in a precarious social position, even though they belonged to the noble Quraysh tribe. This timing is crucial. Being born an orphan in a tribal society meant you were at the bottom of the power structure, despite your lineage.
This influenced everything.
A world between empires
The world in 570 CE was squeezed between two superpowers: the Byzantine Empire and the Sassanid Persian Empire. They were constantly at each other's throats. Arabia was the "empty" space in the middle that everyone wanted to control for trade routes but nobody wanted to actually govern.

When he was born, the "Global North" of the time was falling apart. The plague of Justinian had recently ravaged the Mediterranean. The old world was exhausted.
How We Know What We Know (The Sources)
We don't have a diary from Aminah. We have Isnad.
This is the chain of narration. Islamic history is built on this "he said, she said" system, but turned into a rigorous science.
- Ibn Ishaq: Wrote the first major biography. He lived about 100 years after the Prophet.
- Ibn Sa'd: Wrote Tabaqat Al-Kubra, which is like a massive biographical encyclopedia.
- Astronomy: Modern researchers use software to retro-calculate the moon phases of 570 CE.
When you combine the oral reports with the astronomical data, the window narrows. Most experts land on the period between the 9th and the 12th of Rabi' al-Awwal.
Misconceptions About the Date
People often get confused because they try to find a "Christmas" equivalent.
For a long time, particularly in the Wahhabi or Salafi strands of Islam, celebrating the birth was actually discouraged. They viewed it as an innovation (bid'ah) that wasn't practiced by the Prophet himself.
So, if you go to Saudi Arabia today, you won't see the city decked out in lights for his birthday like you might in Istanbul, Cairo, or Jakarta. This lack of a standardized, universal "holiday" for centuries is partly why the exact date wasn't as rigidly "enforced" in the historical record as, say, the date of a Roman Emperor's coronation.
Actionable Insights for Researching Early Islamic History
If you're trying to pin down dates in this era, keep these things in mind.

First, always check if the source is using the "pre-Islamic" lunar calendar or the "Hijri" calendar. They are different. Pre-Islamic Arabs used to add an extra month every few years to keep the seasons aligned (intercalation), a practice later abolished in the Quran. This makes converting dates from 570 CE to the modern calendar a bit of a mathematical nightmare.
Second, look for the "Year of the Elephant" references. It’s the most reliable cultural anchor we have. If a source doesn't mention the elephant army, it's probably not looking at the primary tradition.
Third, acknowledge the Monday factor. Any date proposed by a historian that doesn't fall on a Monday is usually discarded by Islamic scholars because of the specific Hadith evidence.
Finally, realize that in the 6th century, "exactness" was a different concept. Birthdays weren't celebrated with cakes and candles. They were markers of a person's entry into a tribal lineage. The fact that we have a consensus on the year and the month at all is actually a testament to how much of an impact he had on his contemporaries.
Whether it was April 22nd or a few days off, the shift in world history that began in that year in Mecca is undeniable. You can track the lineage of almost every major event in the Middle East back to that specific coordinate in time.
To explore this further, you should compare the traditional biographies (Sirah) with modern archaeological findings in the Hejaz region. Looking at the "Petra vs. Mecca" debate—while controversial and largely dismissed by mainstream academics—provides an interesting look at how researchers try to use geography to confirm these ancient dates. Stick to peer-reviewed journals like the Journal of Near Eastern Studies for the most sober takes on the 570 CE timeline.
