In other words, a tithi is a time duration between the consecutive epochs that correspond to when the longitudinal angle between the Sun and the Moon is an integer multiple of 12°. Tithis begin at varying times of day and vary in duration approximately from 19 to 26 hours. [2] Every day of a lunar month is called tithi.
A tithi corresponds to the concept of a lunar day. Tithi have Sanskrit numbers according by their position in the pakṣa, i.e. prathama (first), dvitīya (second) etc. The fifteenth, that is, the last tithi of a kṛṣṇa pakṣa is called amāvāsya (new moon) and the fifteenth tithi of a śukla pakṣa is called pūrṇimā (full moon).

Tithi, Nakshatra, Rāśi, Yoga, and Karana depend upon Moon's motions, which are five in number. Panchānga is a Sanskrit word, literally meaning "having five limbs". If these five limbs, for example, the five attributes depending upon Moon, are accurate, an almanac is held to be reliable, because other elements are not so difficult to compute ...
It stands to reason that during the original naming of these months -- whenever that happened -- they were indeed based on the nakshatras that coincided with them in some manner. The modern Indian national calendar is a solar calendar, much like the Gregorian calendar wherein solstices and equinoxes fall on the same date(s) every year.
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).
Some months are considered very auspicious, while a few are considered inauspicious as well. Tamil months start and end based on the Sun's shift from one Rāsi to the other, but the names of the months are based on the star on the start of the pournami in that month. The name of the month is sometimes the name of the star itself.
Indian calendars use 30 lunar phases, called tithi in India. [1] [2] The dark moon tithi is when the Moon is within 12 degrees of the angular distance between the Sun and Moon before conjunction . [3] The New Moon tithi (called Pratipada or Prathama) is the 12 angular degrees after syzygy. Amāvásyā is often translated as new moon since there ...
The traditional lunar calendar system measures time based on the Moon's phases and its relation to the Sun. Unlike solar calendars, it uses units such as tithi (lunar day), pakṣa (lunar fortnight), māsa (lunar month), ṛitu (season), ayanam (half-year), and varsha (lunar year) to structure the year. [17]
