The current system of the Javanese calendar was inaugurated by

Prior to this, the Javanese had used the
Śaka calendar, which has its epoch in 78 CE and uses the
lunisolar cycle for calculating time. Sultan Agung's calendar retained the Saka calendar year system of counting, but differs by using the same

The Javanese calendar year of 1944 occurred entirely within the civil calendar year of 2011. Such years occur once every 33 or 34 Javanese years (32 or 33 civil years). More are listed here:
A Javanese year will be entirely within a Gregorian year of the same number in the year 4195, after which year the number of the Javanese year will always be greater than the number of the concurrent civil year.

Most
Markets no longer operate under this traditional ''Pasaran'' cycle, instead pragmatically remaining open every day of the
Gregorian week. However many markets in Java still retain traditional names that indicated that once the markets only operated on certain ''Pasaran'' days, such as Pasar Legi, or Pasar Kliwon.
Some markets in small or medium size locations will be much busier on the ''Pasaran'' day than on the other days. On the market's name day itinerant sellers appear selling such things as livestock, plants and other products that are either less frequently purchased or are more expensive. This allows a smaller number of these merchants to service a much larger area much as in bygone days.
Javanese astrological belief dictates that an individual's characteristics and destiny are attributable to the combination of the ''Pasaran'' day and the "common" weekday of the Islamic calendar on that person's birthday. Javanese people find great interest in the astrological interpretations of this combination, called the ''Wetonan'' cycle.

counterparts, namely:
These two week systems occur concurrently; thus, a certain Friday may fall on a Kliwon day, and is consequently called ''Jumat Kliwon''.
This combination forms the ''Wetonan'' cycle.
Wetonan cycle
The ''Wetonan'' cycle superimposes the five-day ''Pasaran'' cycle with the seven-day week cycle. Each ''Wetonan'' cycle lasts for 35 (7x5) days. An example of ''Wetonan'' cycle:
:
From the example above, the ''Weton'' for Tuesday May 6, 2008 would be read as ''Selasa Wage''.
The ''Wetonan'' cycle is especially important for divinatory systems, important celebrations, and rites of passage. Commemorations and events are held on days considered to be auspicious.
An especially prominent example, still widely taught in primary schools, is that the ''Weton'' for the

, it is still used in Java for special purposes. The calendar consists of concurrent weeks, and has a set of ten weeks, which have a duration of 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 days.
The first day of the year is considered the first day of all ten weeks. As 210 is not divisible by 4, 8, or 9, extra days must be added to the 4-, 8-, and 9-day weeks.
Dates numbering
For timekeeping, days are numbered within the lunar month (''wulan'') as is common in other calendar systems. The date indicates the change in the moon, and symbolizes the life of a human in the world. This process of revolving life is known as ''cakra manggilingan'' or ''heru cakra''.
On the first day of the month, when the moon is small, it is compared to a newborn baby. The 14th day, called ''Purnama Sidhi'' (full moon), represents a married adult. The next day, called ''Purnama'', occurs as the moon begins to wane. The 20th day, ''Panglong'', symbolizes the point at which people begin to lose their memory. The 25th day, ''Sumurup'', represents the point at which the adult requires care like when they were young. The 26th day, ''Manjing'', represents the return of the human to his or her origin.
Cycles of months
Because a Javanese lunar year is between 11 and 12 days shorter than a civil year, it begins 11–12 days earlier in the civil year following the civil year in which the previous Javanese year began. Once every 33 or 34 Javanese years, or once every 32 or 33 civil years, the beginning of a Javanese year (1 Sura) coincides with one of the first ten days of January. Subsequent New Years move backwards through the civil year back to the beginning of January again, passing through each civil month from December to January.

In the 19th century, the solar month system or ''pranata mangsa'' was much better known among Javanese than the civil or religious year.
The cycle is clearly of Javanese origin, since the specific application to their climate does not match other territories in the
Indonesian archipelago, as well as the usage of Javanese names for the months.
Although the cycle matches the weather pattern well, it is still clearly somewhat arbitrary, as can be seen in the lengths of the months.

Each
lunar year (''taun'') is divided into a series of twelve ''wulan/sasi'' or lunar months. Each consists of 29 or 30 days. This is adapted from the use of months in the Islamic calendar. The names of the month are given below in Javanese and Arabic which can be used interchangeably:
Length of the last month may be 29 or 30 days, depending on whether the year is normal or a leap year (''taun kabisat'').
The cycle of months is sometimes considered metaphorically to represent the cycle of human life. The first nine months represent

Year designation
The
Shalivahana era, which started in 78 CE and continues to be used on Bali, was used in Hindu times on Java, and for well over a century after the appearance of Islam on Java.
When Sultan Agung adopted the Islamic lunar calendar in 1633 CE, he did not adopt the

to designate those years, but instead continued the count of the Shalivahana era, which was 1555 at the time.
As a result, the Anno Javanico does not in effect count from any time.
Cycles of years
Eight ''tahun'' makes up a ''windu''. A single ''windu'' lasts for 81 repetitions of the wetonan cycle, or 2,835 days (about 7 years 9 months in the Gregorian calendar). The ''tahun'' are lunar years, and of shorter length than Gregorian years. The names of the years in the cycle of windu are as follows (in krama/ngoko):
# Purwana/Alip (354 days)
# Karyana/Ehé (354 days)
# Anama/Jemawal (355 days)
# Lalana/Jé (354 days)
# Ngawanga/Dal (355 days)
# Pawaka/Bé (354 days)
# Wasana/Wawu (354 days)
# Swasana/Jimakir (355 days)
The ''windu'' are then grouped into a cycle of four:
# Windu Adi
# Windu Kunthara
# Windu Sengara
# Windu Sancaya
The cycles of ''wulan'', ''tahun'', and ''windu'' are derived from the
Saka calendar.
''Windu are no longer used much in horoscopy, but there is evidence that it was previously used by
court officials to predict trends. The passing of a ''windu'' is often seen as a milestone and deserving a

ritual feast.
Kurup
The ''kurup'' is a period of 120 ''tahun'', or lunar years. There are thus 1440 lunar months, or 15 ''windu'' in a ''kurup''. One day is dropped from the last month of Besar having 30 days, resulting in the last ''windu'' of the ''kurup'' having one less day than usual. Thus, the total number of days in a ''kurup'' is 42,524 (2,835 days in a ''windu'' x 15 ''windu'' - 1 day). This is the same number of days as in 120 lunar years of the Tabular Islamic Calendar.
Each ''kurup'' is named for date of the wetonan cycle on which the ''kurup'' commences. As this always falls in the Alip (first) year of the ''windu'', it is prefixed with Alip. The current ''kurup'' started on Tuesday, March 24 of 1936 CE, which corresponds to Muharram 01 of 1355 AH in the Tabular Islamic Calendar, and will end on Sunday, August 25 of 2052 CE. As the wetonan date of that day was Selasa Pon, the ''kurup'' is named Alip Selasa Pon.
The next ''kurup'' will commence on Monday, August 26 of 2052 CE, which corresponds to Muharram 01 of 1475 AH in the Tabular Islamic Calendar, and will end on Saturday, January 28 of 2169 CE, and will be named Alip Senin Pahing.
