Hijri To Gregorian​

Introduction
In a country like Saudi Arabia, where most of the aspects of its capacity are modernizing rapidly, the Hijri calendar stands out as an inseparable part of its identity-both culturally and religiously. From daily life to state affairs, "Hijri calendar" explains time, the adherence to religious dates, and the national rhythm flowing through the veins of Saudi society. The paper searches for how modern Saudi Arabia uses the Hijri calendar and continues to become significant to this date.
How the Hijri Calendar Shapes Saudi Daily Life
In Saudi Arabia, the Hijri calendar is used along with the Gregorian calendar, mainly for religious and cultural purposes. For example, the beginning of the Islamic month of Ramadan is determined by the lunar sighting, while the start of Hajj season is computed in accordance with the Hijri calendar. Public holidays, school schedules, and business hours might be scheduled around a certain "Hijri date today" during the month of Ramadan.
The Continued Importance of the Hijri Calendar
Though the Gregorian calendar is followed more and more in international communications and commerce, the Hijri calendar remains at the center of Saudi life. All government documents, state holidays, and the times of religious events are all calculated according to the Hijri calendar system. For example, the date for Islamic New Year's and the celebration of Eid-El Fitri rely on the Hijri calendar system alone.

Introduction
If you have ever wondered why the "Hijri New Year" greets different Gregorian calendar sets each year, you're not alone. Unlike the Gregorian calendar, which is fixed to Earth's orbit around the sun, the Hijri calendar is based on the lunar cycle. We are going to talk in this paper about why the Hijri New Year is not falling in the same particular month of the Gregorian calendar and how it is going to affect an Islamic year.
Difference Between Solar and Lunar Calendars
Apart from that, the main difference between the Hijri calendar and Gregorian is that the latter is based on a solar cycle whereas the former draws its origin from the orbit of the moon around the Earth. A year in a solar system has approximately equal days of 365.25 days; whereas its lunar counterpart only has 354 or 355 days. Considering this fact, the Hijri calendar becomes shorter by approximately ten to twelve days every year compared to the Gregorian calendar.
Implications for the Hijri New Year
Because the Hijri year is shorter, the "Hijri New Year" then progresses toward each Gregorian year by approximately 10-12 days. This explains why Islamic New Year falls on a different date with every passing year in the Gregorian calendar. In one year, it might happen in winter, while in another, it could happen during summer, depending on the cycle of the moon.
