, the 6th-century ''Romaka'' by Latadeva and ''Panca Siddhantika'' by Varahamihira, the 7th-century ''Khandakhadyaka'' by Brahmagupta and the 8th-century ''Sisyadhivrddida'' by Lalla. These texts present Surya and various planets and estimate the characteristics of the respective planetary motion. Other texts such as ''Surya Siddhanta'' dated to have been completed sometime between the 5th century and 10th century present their chapters on various deified planets with stories behind them. The manuscripts of these texts exist in slightly different versions. They present Surya, planet-based calculations and Surya's relative motion to earth. These vary in their data, suggesting that the text were open and revised over their lives. For example, the 1st millennium CE Hindu scholars calculated the sidereal length of a year as follows, from their astronomical studies, with slightly different results: The Hindu texts used the lunar cycle for setting months and days, but the solar cycle to set the complete year. This system is similar to the Jewish and Babylonian ancient calendars, creating the same challenge of accounting for the mismatch between the nearly 354 lunar days in twelve months, versus over 365 solar days in a year. They tracked the solar year by observing the entrance and departure of ''Surya'' (sun, at sunrise and sunset) in the constellation formed by stars in the sky, which they divided into 12 intervals of 30 degrees each. Like other ancient human cultures, Hindus innovated a number of systems of which intercalary months became most used, that is adding another month every 32.5 months on average. As their calendar keeping and astronomical observations became more sophisticated, the Hindu calendar became more sophisticated with complex rules and greater accuracy. According to Scott Montgomery, the ''Siddhanta'' tradition at the foundation of Hindu calendars predate the Christian era, once had 18 texts of which only 5 have survived into the modern era. These texts provide specific information and formulae on motions of sun, moon and planets, to predict their future relative positions, equinoxes, rise and set, with corrections for prograde, retrograde motions, as well as parallax. These ancient scholars attempted to calculate their time to the accuracy of a ''truti'' (29.63 microseconds). In their pursuit of accurate tracking of relative movements of celestial bodies for their calendar, they had computed the mean diameter of the earth, which was very close to the actual 12,742 km (7,918 mi). Hindu calendars were refined during the
Gupta era The Gupta era is a historical calendar era that begins from c. 318–319 CE. It was used by the Gupta emperors, as well as their vassals and their successors in present-day northern India and Nepal. It is identical to the Vallabhi era (or Valabh ...

Months


Solar month and seasons

The Hindu calendar divides the zodiac into twelve division called ''rāśi''. The time taken by the Sun to transit through a ''rāśi'' is a solar month whose name is identical to the name of the ''rāśi.'' In practice, solar months are mostly referred as ''rāśi'' (not months). The solar months are named differently in different regional calendars. While the Malayalam calendar broadly retains the phonetic Sanskrit names, the Bengali and Tamil calendars repurpose the Sanskrit ''lunar month names'' (Chaitra, Vaishaka etc.) as follows: * The Tamil calendar replaces Mesha, Vrisha etc. with Chithirai, Vaigasi etc. * The Bengali calendar is similar to the Tamil calendar except in that it starts the year with Boiśākh (instead of Choitrô), followed by Jyoisthô etc. The Assamese and Odia calendars too are structured the same way.

Lunar months

Lunar months are defined based on lunar cycles, i.e. the regular occurrence of new moon and full moon and the intervening waxing and waning phases of the moon.


Paksha

A lunar month contains two fortnights called '' pakṣa'' (पक्ष, literally "side"). One fortnight is the bright, waxing half where the moon size grows and it ends in the full moon. This is called "Gaura Paksha" or ''Shukla Paksha''. The other half is the darkening, waning fortnight which ends in the new moon. This is called "Vadhya Paksha" or ''Krishna Paksha''. The Hindu festivals typically are either on or the day after the full moon night or the darkest night (''amavasya'', अमावास्या), except for some associated with

Amanta and Purnimanta systems

Two traditions have been followed in the Indian subcontinent with respect to lunar months: the amanta tradition, which ends the lunar month on

As a consequence, in the amanta tradition, Shukla paksha precedes Krishna paksha in every lunar month, whereas in the purnimanta tradition, Krishna paksha precedes Shukla paksha in every lunar month. As a result, a Shukla paksha will always belong to the same month in both traditions, whereas a Krishna paksha will always be associated with different (but succeeding) months in each tradition. {, class="wikitable" , +style="text-align:left", Variations in the naming of lunar months ! !Krishna Paksha !Shukla Paksha !Krishna Paksha , - style="text-align:center" , style="text-align:left" , Amanta , Phalguna , colspan="2" , Chaitra , - style="text-align:center" , style="text-align:left" , Purnimanta , colspan="2" , Chaitra , Vaishaka The amanta (also known as Amavasyanta or Mukhyamana) tradition is followed by most Indian states that have a peninsular coastline (except

, who wanted to return to the Vedic roots. The presence of this system is one of the factors considered in dating ancient Indian manuscripts and epigraphical evidence that have survived into the modern era. The two traditions of Amanta and Purnimanta systems have led to alternate ways of dating any festival or event that occurs in a Krishna paksha in the historic Hindu, Buddhist or Jain literature, and contemporary regional literature or festival calendars. For example, the Hindu festival of Maha Shivaratri falls on the fourteenth lunar day of ''Magha's'' Krishna paksha in the Amanta system, while the same exact day is expressed as the fourteenth lunar day of ''Phalguna's'' Krishna paksha in the Purnimanta system. Both lunisolar calendar systems are equivalent ways of referring to the same date, and they continue to be in use in different regions, though the Purnimanta system is now typically assumed as implied in modern Indology literature if not otherwise specified.


List of Lunar Months

The names of the Hindu months
vary by region. Those Hindu calendars which are based on lunar cycle are generally phonetic variants of each other, while the solar cycle are generally variants of each other too, suggesting that the timekeeping knowledge travelled widely across the Indian subcontinent in ancient times. During each lunar month, the Sun transits into a sign of the zodicac (
sankranti Sankranti ( sa, संक्रान्ति ''saṁkrānti or saṅkramaṇa'') means transmigration of the Sun from one zodiac to another in Indian astronomy. Each Sankranti is marked as the beginning of a month in the sidereal solar calen ...
). The lunar month in which the Sun transits into Mesha is named Chaitra and designated as the first month of the lunar year. A few major calendars are summarized below:

Corrections between lunar and solar months

Twelve Hindu mas (māsa, lunar month) are equal to approximately 354 days, while the length of a sidereal (solar) year is about 365 days. This creates a difference of about eleven days, which is offset every (29.53/10.63) = 2.71 years, or approximately every 32.5 months. Purushottam Maas or Adhik Maas is an extra month that is inserted to keep the lunar and solar calendars aligned. The twelve months are subdivided into six lunar seasons timed with the agriculture cycles, blooming of natural flowers, fall of leaves, and weather. To account for the mismatch between lunar and solar calendar, the Hindu scholars adopted intercalary months, where a particular month just repeated. The choice of this month was not random, but timed to sync back the two calendars to the cycle of agriculture and nature. The repetition of a month created the problem of scheduling festivals, weddings and other social events without repetition and confusion. This was resolved by declaring one month as ''Shudha'' (pure, clean, regular, proper, also called ''Deva'' month) and the other ''Mala'' or ''Adhika'' (extra, unclean and inauspicious, also called Asura masa). The Hindu mathematicians who calculated the best way to adjust the two years, over long periods of a ''yuga'' (era, tables calculating 1000 of years), they determined that the best means to intercalate the months is to time the intercalary months on a 19-year cycle. This intercalation is generally adopted in the 3rd, 5th, 8th, 11th, 14th, 16th and 19th year of this cycle. Further, the complex rules rule out the repetition of Mārgasirsa (also called ''Agrahayana''), Pausha and
Maagha Maagha (Hindi: माघ ''maagh'') is a month of the Hindu calendar. In India's national civil calendar, it's the eleventh month of the year, corresponding to January/February in the Gregorian calendar.Henderson, Helene. (Ed.) (2005) ''Holida ...
lunar months. The historic Hindu texts are not consistent on these rules, with competing ideas flourishing in the Hindu culture.


Rare corrections

The Hindu calendar makes further rare adjustments, over a cycle of centuries, where a certain month is considered ''kshaya'' month (dropped). This occurs because of the complexity of the relative lunar, solar and earth movements. Underhill (1991) describes this part of Hindu calendar theory: "when the sun is in perigee, and a lunar month being at its longest, if the new moon immediately precedes a samkranti, then the first of the two lunar months is deleted (called ''nija'' or ''kshaya'')." This, for example, happened in the year 1 BCE, when there was no new moon between Makara samkranti and Kumbha samkranti, and the month of Pausha was dropped.


Day

Just like months, the Hindu calendar has two measures of a day, one based on the lunar movement and the other on solar. The solar (''

'') day or civil day, called ''divasa'' (), has been what most Hindus traditionally use, is easy and empirical to observe, with or without a clock, and it is defined as the period from one sunrise to another. The lunar day is called ''tithi'' (), and this is based on complicated measures of lunar movement. A lunar day or ''tithi'' may, for example, begin in the middle of an afternoon and end next afternoon. Both these days do not directly correspond to a mathematical measure for a day such as equal 24 hours of a solar year, a fact that the Hindu calendar scholars knew, but the system of ''divasa'' was convenient for the general population. The ''tithi'' have been the basis for timing rituals and festivals, while ''divasa'' for everyday use. The Hindu calendars adjust the mismatch in ''divasa'' and ''tithi'', using a methodology similar to the solar and lunar months. A ''tithi'' is technically defined in Vedic texts, states

, as "the time required by the combined motions of the sun and moon to increase (in a bright fortnight) or decrease (in a dark fortnight) their relative distance by twelve degrees of the zodiac. These motions are measured using a fixed map of celestial zodiac as reference, and given the elliptical orbits, a duration of a ''tithi'' varies between 21.5 and 26 hours, states Cort. However, in the Indian tradition, the general population's practice has been to treat a tithi as a solar day between one sunrise to next. A lunar month has 30 ''tithi''. The technical standard makes each ''tithi'' contain different number of hours, but helps the overall integrity of the calendar. Given the variation in the length of a solar day with seasons, and moon's relative movements, the start and end time for ''tithi'' varies over the seasons and over the years, and the ''tithi'' adjusted to sync with ''divasa'' periodically with intercalation.


Weekday/Vāsara

''Vāsara'' refers to the weekdays in Sanskrit. Also referred to as ''Vara'' and used as a suffix. The correspondence between the names of the week in Hindu and other Indo-European calendars are exact. This alignment of names probably took place sometime during the 3rd century CE. The weekday of a Hindu calendar has been symmetrically divided into 60 ''ghatika'', each ''ghatika'' (24 minutes) is divided into 60 ''pala'', each ''pala'' (24 seconds) is subdivided into 60 ''vipala'', and so on.

Five limbs of time

The complete Vedic calendars contain five ''angas'' or parts of information: lunar day (tithi), solar day (diwas), asterism (naksatra), planetary joining (yoga) and astronomical period (karanam). This structure gives the calendar the name ''Panchangam''. The first two are discussed above.

The longitude of the sun and the longitude of the moon are added, and normalised to a value ranging between 0° to 360° (if greater than 360, one subtracts 360). This sum is divided into 27 parts.

Karaṇa

A karaṇa is half of a
tithi In Vedic timekeeping, a ''tithi'' is a uration of two faces of moon that is observed from earth known as ''milа̄lyа̄'' (𑐩𑐶𑐮𑐵𑐮𑑂𑐫𑐵𑑅, मिलाल्याः) in Nepal Bhasa, or the time it takes for the longi ...
. To be precise, a karaṇa is the time required for the angular distance between the sun and the moon to increase in steps of 6° starting from 0°. (Compare with the definition of a tithi.) Since the tithis are 30 in number, and since 1 tithi = 2 karaṇas, therefore one would logically expect there to be 60 karaṇas. But there are only 11 such karaṇas which fill up those slots to accommodate for those 30 tithis. There are actually 4 "fixed" (sthira) karaṇas and 7 "repeating" (cara) karaṇas. The 4 # Śakuni (शकुनि) # Catuṣpāda (चतुष्पाद) #

) (भद्रा) * Now the first half of the 1st ''tithi'' (of Śukla Pakṣa) is always ''Kiṃtughna karaṇa''. Hence this karaṇa is "fixed". * Next, the 7-repeating karaṇas repeat eight times to cover the next 56 half-''tithis''. Thus these are the "repeating" (cara) karaṇas. * The 3 remaining half-''tithis'' take the remaining "fixed" karaṇas in order. Thus these are also "fixed" (sthira). * Thus one gets 60 karaṇas from those 11 preset karaṇas. The Vedic day begins at sunrise. The karaṇa at sunrise of a particular day shall be the prevailing karaṇa for the whole day. (citation needed )
