Gregorian
A solar calendar is a type of calendar that is based on the position of the Earth in relation to the sun. This means that the calendar is organized around the length of the solar year, which is the time it takes for the Earth to complete one orbit around the sun. Solar calendars are used to keep track of the seasons and to organize events and appointments throughout the year. Some examples of solar calendars include the Gregorian Calendar, the Julian Calendar, and the Hindu Calendar. The solar calendar is the most widely used calendar system in the world and is the standard for civil and commercial purposes.
A secular calendar is a system of timekeeping that is not tied to religious events or observances. It typically focuses on civil or societal events, such as workdays, holidays, and seasons, rather than religious holidays or rituals. Common examples include the Gregorian calendar, which is widely used around the world, and the fiscal calendar used by businesses for financial planning. Secular calendars aim to provide a neutral framework for organizing time in a diverse society.
Today, we primarily use the Gregorian calendar, which is a reform of the Julian calendar introduced by Pope Gregory XIII in 1582. It is a solar calendar with 12 months and a year length of 365 days, with a leap year every four years to account for the extra 0.25 days in the solar year. The Gregorian calendar is widely adopted around the world for civil purposes, although various cultures still observe their own traditional calendars for religious or cultural events.
The current Gregorian calendar was introduced in October 1582 by Pope Gregory XIII. It replaced the Julian calendar, which had been in use since 45 BC. However, not all countries adopted the Gregorian calendar at the same time; for instance, Great Britain and its colonies switched in 1752. Today, the Gregorian calendar is the most widely used civil calendar around the world.

But there are other types of unofficial calenders used by some groups of people around the world. * Calenders have public/bank/mercantile holidays marked on them specific to that country. * In Sri Lanka, calendars have Full moon days marked on them, because Full moon days are public holidays. * Chinese calendar is a lunisolar calendar, incorporating elements of a lunar calendar with those of a solar calendar. * Islamic (Muslim/Hijri) calendar is a lunar calendar, used to date events in Muslim countries, by Muslims to determine the days to celebrate Islamic holy days and festivals. no,. because in my country there are lot of islands and its used a different calender from each island to the other islands

The Gregorian Calendar has become the standard civil calendar used worldwide. It was introduced by Pope Gregory and took hundreds of years to be accepted as a global standard. Before that, the Julian Calendar, introduced by Julius Caesar, was the civil and religious calendar used in Christian lands. The Julian Calendar is still used in the Eastern Orthodox Church and a few other places. The Jewish Calendar, Islamic calendar, Hindu Calendar and Chinese Calendar all serve to set the dates of festivals celebrated by their respective communities, as well as being used for various other purposes. Various indigenous groups around the world may also have calendars, but to be a formal calendar and not merely a way to recon time, it needs a system of recording dates, which is to day, calendars are for literate cultures. One important calendar is left out above: The Mayan calendar. It is no longer in use, having been forcefully replaced by the Gregorian Calendar when the Conquistadors invaded, but it has been decoded, and you can find software to convert between Gregorian and Mayan dates.
