How many weeks in the Gregorian and Hijri year? The Gregorian year and the Hijri year are used in history, and there are a group of countries that use the Gregorian date or the so-called solar date as their primary date, and there are other countries that use the Hijri date or the lunar date, and each of the two dates have indications for the months and weeks in it. Through the reference site, we will learn about the number of weeks in each of the Gregorian and Hijri years.

How many weeks in a Gregorian and Hijri year?

Many peoples have adopted their own calendars, such as the Egyptian calendar, the Syriac calendar, the Persian calendar, the Bahai calendar, the Libyan Jamahiriya calendar, the Hebrew calendar, in addition to the Roman calendar. Although these calendars differ in their characteristics from each other, they can be divided into two main types: the solar based on the Earth’s rotation around the sun, called the Gregorian calendar, and the lunar one based on the moon’s rotation around the Earth, called the Hijri calendar. The number of weeks in each calendar varies as follows:

Number of weeks in a calendar year: The number of weeks of the Gregorian year is approximately fifty-two weeks (52 weeks) and one day, as these weeks are distributed over 12 months, for an ordinary year. A leap year contains 52 weeks and two days.
Number of weeks in the Hijri year: The Hijri year has a total of 51 weeks (approximately). The Hijri year includes twelve months, some of which have twenty-nine days, and some of them have thirty days. Therefore, the average total of the days of the Hijri year is 354 days, meaning that there is a difference between it and the Gregorian year of about 11 days.

Gregorian Year

The Gregorian year is considered a solar year, and the number of its days is 365, and sometimes it is 366 in a leap year. The Gregorian calendar is the universally used calendar. This name was given to the Gregorian calendar in reference to the birth of Jesus, peace be upon him. This calendar was also called the “Gregorian” calendar after Pope Gregory the thirteenth in Rome. Pope Gregory is also considered the one who modified the Greek calendar, to become the calendar we use today.[1]

How to calculate the weeks of the calendar year

The number of weeks in a calendar year can be calculated as follows:

In an ordinary year: The Gregorian year consists of 365 days. One week consists of 7 days. The number of days in the Gregorian year is divided by the number of days of the week as follows: 365 days ÷ 7 days = 52,143 weeks. So the number of weeks in a calendar year equals 52 weeks and one day.
In a leap year: A leap year has 366 days. One week consists of 7 days. The number of days in a leap calendar year is divided by the number of days of the week as follows: 366 days ÷ 7 days = 52.268 weeks. So the number of weeks in a leap year is 52 weeks and 2 days.

Because it is related to the incident of the migration of the Messenger – may God bless him and grant him peace -.

How to calculate the weeks of the Hijri year

The number of weeks in the Hijri year can be calculated as follows: The Hijri year consists of 354 days. One week consists of 7 days.

Because their names differed from one tribe to another. They agreed to name each month

City of Muharram: It was called by this name because it is the Muharram month, and it is one of the four sacred months, in which Muslims are not permitted to fight.

City zero: It was called that because Arab homes were whistling during it, meaning they were devoid of its people, because they went out in it in search of food and sustenance after the end of the sacred months, and they were traveling to escape the summer heat.
Rabi` al-Awwal and Rabi` al-Thani: They were named by this name because they were named in the spring
The first inanimate and the second inanimate: They were called by this name, because their name came in the winter, when the water freezes.
Rajab month: This name was given to him because it means greatness, and it is one of the months in which fighting was forbidden.
Shaban: This month was called by that name because the Muslims in this month split into tribes for war and fighting after the sacred months of Muharram and Rajab.
Ramadan: It is considered one of the greatest months of the Hijri year, because the Holy Qur’an was revealed in it and Muslims fast and draw close to God Almighty.
Shawwal: It is the blessed month of Eid al-Fitr, when camels become paralyzed, i.e. their milk decreases and dries up, hence the name.
Zul Qi’dah: It was called by that name because Muslims refrain from traveling and conquest, and it is one of the sacred months.
Dhul-Hijjah: It is the last month of the Hijri year and in it there is the Day of Arafat and Eid al-Adha, and it was called that because it is the pilgrimage season and Muslims go to the Kingdom of Saudi Arabia for the purpose of the Sacred House of God.
