Depending on the type of the religion ,their calenders differ. In the case of an ethnic religion, the calender is typically more clustered distribution than a universalizing religion, in part because its holidays are based on the distinctive physical geography of the homeland.

In an ethnic religion, there is a celebration of the seasons. The calender is determined by the annual cycle of variation in climate conditions. Therefore, knowing the calender is important for successful agriculture for the year. The calender is determined by the temperatures and precipitation which helps the farmers to know when they should plant or harvest their crops. People in the ethnic religions have rituals based on favorable environmental conditions or to give thanks for past success.

Such as, the Bontok people in the Philippines revolve around the agricultural calender . They have sacred moments called, obaya, this is when the rice field is inti ally prepared, when the seedlings are transplanted, when the harvest has begun, and when the harvest is done. Knowing these dates is essential in the way these people live. Solstice has a special importance to ethnic religions. This is the shortest day and longest night of the year. This s where the Sun appears to be low in the sky and stand still, as is the Latin meaning of solstice, to stand still.

The Jewish Calender also revolves around the agricultural system. In Israel, the grain crops are planted in Autumn, therefore it is expected that the two most holiest days in the year, Rosh Hashanah( New Years) and Yom Kippur(Day of Atonement) happen in Autumn. Sukkot celebrates the final gathering of fruits for the year, therefore they pray for rain and success in the future. Pesach is when they offer God the first fruits in the year. Shavuot is the end of the grain harvest. All these holidays have to do with the agriculture of the home land. These came popular from the liberation of the Jews from the slavery in Egypt called Pesach. Their temporary shelter was called their booths. Rather than using a solar calender like North Americans, they use a lunar calender. The end of the full moon and the appearance of the new moon mark a new month as is the Islamic religion does. Therefore their year has 350 days. In order to balance the years, they add an extra month seven out of every 19 years.
In a universalizing religion, the holidays on the calender are determined on the important events in the founder's life. For Christians, they associate their holidays with seasonal variations in the calender, but not by climate and the agricultural cycle. This does not affect their liturgy or rituals.

In contrast, universalizing religion's calender is based on major holidays. These holidays go along with the events in life of the founder other than the changing of the seasons of a particular place.

Islam and Baha'i calendar are different from the average calender. The Islamic religion also uses the lunar calender, therefore their holidays do not come on the same day as always. They come in different seasons from generation to generation. However, the Baha'i use a calender that has 19 months with each 19 days in it, with an extra 4 intercalary days. They also have a Nineteen Day feast where they pray , read scriptures, and discuss community activities, the first day of every month.
-nevertheless, many holidays in the Islamic calendar go along with events in the life of their founder Mohamed.

Christian, Buddhist, and Sikh Holidays are mainly based on important dates in the founder's life. Such as, for Christians, they celebrate Christ's birth and death, but not all Christians celebrate this on the same day. Protestants and Roman Catholics use the Gregorian calender, while Eastern Orthodox use the Julian calender. Buddhist celebrate Buddha's birth, Enlightenment, and death. Not all Buddhist celebrate these days on the same day. The Japanese Buddhists celebrate each in a different month, while the Theravadist Buddhists observe all three in April. Also, the Sikhism holiday's occur on the births and deaths of their ten gurus. Their main holiday is the day when the Holy Granth was installed as the religion's spiritual guide. By them commemorating historical events, they make them differ from Hinduism in India. Therefore, they become a universalizing religion.
