Seasonal and harvest festivals

Seasonal festivals, such as Beltane, are determined by the solar and the lunar calendars and by the cycle of the seasons, especially because of its effect on food supply, as a result of which there is a wide range of ancient and modern harvest festivals. Ancient Egyptians relied upon the seasonal inundation caused by the Nile River, a form of irrigation, which provided fertile land for crops. In the Alps, in autumn the return of the cattle from the mountain pastures to the stables in the valley is celebrated as Almabtrieb. A recognized winter festival, the Chinese New Year, is set by the lunar calendar, and celebrated from the day of the second new moon after the winter solstice. Dree Festival of the Apatanis living in Lower Subansiri District of Arunachal Pradesh is celebrated every year from July 4 to 7 by praying for a bumper crop harvest.

Midsummer or St John's Day, is an example of a seasonal festival, related to the feast day of a Christian saint as well as a celebration of the time of the summer solstice in the northern hemisphere, where it is particularly important in Sweden. Winter carnivals also provide the opportunity to utilise to celebrate creative or sporting activities requiring snow and ice. In the Philippines, each day of the year has at least one festival dedicated to harvesting of crops, fishes, crustaceans, milk, and other local goods.
