Does a new day start after maghrib
In Islamic law and tradition, the day is divided into 24 hours, but the timing of the day is calculated differently than in the Western Gregorian calendar.
In the Islamic calendar, the day starts at sunset, which is called "Maghrib" in Arabic. This is because the Prophet Muhammad (peace be upon him) said, "The day begins at sunset and ends at sunrise." (Bukhari and Muslim)
So, according to this definition, a new day starts after Maghrib, which is the time of sunset. This means that the day of Friday, for example, starts at sunset on Thursday and ends at sunset on Friday.
However, it's worth noting that in modern times, many Muslims have adopted the Western concept of a 24-hour clock, where the day starts at midnight and ends at midnight. This is especially true in countries where the Islamic calendar is not the official calendar.
In summary, from a traditional Islamic perspective, a new day starts after Maghrib (sunset), but in modern times, many Muslims use the Western concept of a 24-hour clock.
