The terms páhing, pon, wági, kalíwon, and mánis or légi, are applied to the days of the panchawára, or week of five days, which is common throughout the country, and by which the markets are universally regulated[199].
Besides this week of five days, which seems to be by far the most ancient as well as the most generally adopted among them, the Javans have a week of seven days as follows.
| Díti, Sunday, | which corresponds with the Hindu | Rowi. |
| Sóma, Monday | Soma. | |
| Ang'gára, Tuesday | Mangala. | |
| Búdha, Wednesday | Budha. | |
| Raspáti, Thursday | Vrihaspati. | |
| Súkra, Friday | Sukra. | |
| Sanischára or Túmpah, Saturday | Sani. |
The Arabic terms are usually employed to express the months.
The weeks of seven days, considered with reference to the seasons, are termed wúku. Thirty of these are said to have been established in commemoration of the victory obtained over Wátu Gúnung[200]. These thirty have again six principal divisions, each consisting of thirty-five days, and commencing on the day when díti and páhing fall together.
Each wúku, is dedicated to its particular deity, and has its appropriate emblems in the Javan system of judicial astrology. The names of the wúku and of the deities to which each is considered sacred are as follow:
The twelve seasons, Mángsa, of which an account has been given, when treating of the agriculture of the Javans, are said to be determined by reference to the sun's course at the commencement of each of these divisions.
When a want of rain is experienced, it is a custom for the people of the village or town to assemble, and for a wáyang to be performed upon the story of Wátu Gúnung and Déwi Sínta. On these occasions two sticks of the dark coloured sugar-cane, two young and two old cocoa-nuts, two bundles of different coloured pári, two bundles of the flowers of the areca-nut, a piece of white cloth, sweet scented oils, two fowls and two ducks, are placed by the side of the dálang during the performance, and are afterwards considered his property.
The term wíndu is used to express a revolution or cycle of years. The Javans refer to wíndu of eight years, a wíndu of twelve years, a wíndu of twenty years, and a wíndu of thirty-two years. The wíndu of eight years, now in use, seems to have been borrowed from the Arabs; but this is more frequently considered of seven years, each year taking its name from one of the following animals, according to the day of the week on which it begins.
