Religious movements, sects and even festivals will appear and disappear. Occasionally, one will endure and a significant segment of society will recognise it as a legitimate spiritual path or celebration. Eventually, the larger society may lend its approval. Of course, contemporary views of what are socially defined as religion, denomination, or sect may also change in the future. In these cases, future editions may well include religions, denominations and sects not presently included.
With regard to any particular festival, the guiding principle is how broadly the different segments of that religion accept the festival. The festivals noted in Multi Faith Calendar are annual events that people celebrate once during the course of a solar or lunar year.
The common theme of calendar making is the desire to organise units of time to satisfy the needs and pre occupations of society. In addition to serving practical purposes, the process of organization provides a sense, however illusory, of understanding and controlling time itself.
Other cycles of time are also important: the new or full moon, a season, a week day (for example, the Jewish Shabbat or the Friday prayers in a mosque), or a daily cycle (such as the Eucharist for traditional Christian communities). While these cycles are less obvious, they are as important to the faithful as annual festivals.
The actual time between new moons varies with the seasons. There can be as much as 15 hours difference between a month's true lunar conjunction and its mean conjunction. The earth rotates at an irregular rate. The rotational speed of the Earth changes slightly for several reasons. Large scale movements of water and changes in the atmosphere affect the Earth's angular momentum (like when a pirouetting ballerina moves her arms in or out). Tidal friction from the moon, which results in the rise of tides in the ocean, diminishes the speed of rotation. Physical processes occurring on or within the Earth also affect the earth's rotation. The length of the year increases slightly for a variety of reasons. These include: the gradual slowing of the Earth's rotation, slow changes in the Earth's orbit due to other planets and the moon, as well as regular effects due to the slow precession of the Earth's axis of rotation.
So how do different calendars deal with this? The Christian calendar is purely solar. The tides and the lunar phases have no obvious connection to the calendar; you have to calculate them. Furthermore, there is no way to determine exactly when one date ends and the next begins, without inventing and carrying a timepiece. (In return for this inconvenience, this calendar acquires the feature that all its dates are of equal duration.) Similarly, there is no objective difference between the end of one month and the beginning of another. The idea of grouping the dates into months is anachronistic in a purely solar calendar. When comparing calendars, remember that the three astronomical cycles cannot be reconciled. All fixed calendars will require adjustment.
The complexity of calendars arises because these cycles of revolution do not comprise an Integral number of days, and because astronomical cycles are neither constant nor perfectly Commensurable with each other, the tropical year is defined as the mean interval between Vernal equinoxes; this corresponds to the cycle of seasons on average. The ancient astronomy, affecting astrological beliefs, cannot be dismissed simply because many of them go against conventional beliefs and customs but, being in natural law merits serious study and debate.
Our Multifaiths website is used by the world's foremost professional, industry standard, for accurate public holidays listings, long-term forecasts and date calculations. The Multifaith Public Holidays calendar is the professional online source of international Public Holidays, covering many countries of the world
The western world is most familiar with the Gregorian solar calendar, now used internationally for business. As with other solar calendars, the time it takes the earth to make one revolution around the sun determines the length of the solar Gregorian year. (Mean Value) We hope this Multifaith Calendar will broaden understanding and acceptance of alternate paths of spirituality consistent with what most people presently regard as an authentic religious festivals.

How accurate are dates of the Public Holidays Database? Since 1999, we have developed mathematical and astronomical calculation software libraries, These unique software tools, in conjunction with our database of predictive rules, enable us to easily forecast worldwide public holidays for the next 50 years and beyond. Which is visited daily by diary and calendar publishers, financial institutions, logistics companies, shipping and brokerage firms, government agencies, NGOs, and even Education sector websites. In addition, community workers for whom accurate astronomical data are vital, to generate their calendar that contain astronomical data.
Food customs, the social or religious regulations surrounding the preparation, serving, and eating of food and drink. Eating together (commensality) is a basic human act, which denotes the friendliness and common purpose of a group. Feasts are often used to mark rites of passage, such as marriages, or religious festivals, such as Christmas, and symbolic meals play an important part in some religion.
Fasting, the avoidance of food, may also be regarded as a religious act, as in various ascetic cults, or as in temporary periods of fasting like Ramadan. All societies select certain foods as especially valuable and mark off others as wholly inedible or taboo. Many ritual observances include some measures of this sort, while some religions forbid certain sorts of food under any circumstances.
Dietary laws within Judaism forbid the eating of any foods not regarded as kosher or legitimate; and alcohol, among other things, is strictly prohibited for Muslims. Other food prohibitions can be calendrical: that is, certain forms of food may not be eaten on certain days or at particular times of the year. Certain types of food may also be seen as the privilege of certain persons, or groups of people, and in this way may serve as an indicator of social status and rank.
