The Hindu calendar is lunisolar but most festival dates are specified using the lunar portion of the calendar. A lunar day is uniquely identified by three calendar elements: māsa (lunar month), pakṣa (lunar fortnight) and tithi (lunar day).
Furthermore, when specifying the masa, one of two traditions are applicable, viz. amānta / pūrṇimānta. If a festival falls in the waning phase of the moon, these two traditions identify the same lunar day as falling in two different (but successive) masa.
A lunar year is shorter than a solar year by about eleven days. As a result, most Hindu festivals occur on different days in successive years on the Gregorian calendar.
During the festival, the celebrants illuminate their homes, temples and workspaces with diyas (oil lamps), candles and lanterns.[8] Hindus, in particular, have a ritual oil bath at dawn on each day of the festival.[23] Diwali is also marked with fireworks as well as the decoration of floors with rangoli designs and other parts of the house with jhalars. Food is a major focus with families partaking in feasts and sharing mithai.[24] The festival is an annual homecoming and bonding period not only for families,[16][17] but also for communities and associations, particularly those in urban areas, which will organise activities, events, and gatherings.[25][26] Many towns organise community parades and fairs with parades or music and dance performances in parks.[27] Some Hindus, Jains, and Sikhs will send Diwali greeting cards to family near and far during the festive season, occasionally with boxes of Indian confectionery.[27] Another aspect of the festival is remembering the ancestors.[28]
