(1) Panchangam program for any month and year
(2) Bio Rhythm Program
(3) Fun with numerology

Note:

This is not a piece about astrology and constellation interpretations. This page is to share about time measurement, constellations and objects in the sky. All Calendars are broadly of three types:
(1) Solar calendar (saura maana) based on: (a) seasonal (equinox) and (b) Sun transit along zodiac (in elliptic)
(2) Lunar calendar (chaandra maana) based on:
(a) phases (waxing, waning, tithi or thyathi). Lunar month is marked from Purnima to Purnima (Purnimanta method) or from Amavasya to Amavasya (Amanta method). Synodic month is 29.5306 days and
(b) Moon transit along zodiac (in elliptic) with reference to 27 or 28 constellations or stars. Nakshatra or star-clusters or constellations, which lie along the ecliptic, or path of the sun/moon. An individual's nakshatra, or birth star, is the constellation, to which moon was aligned at the time of birth. Sidereal month 27.321661 days
(3) Indian systems uses mixing both in different combination. So there are many lunisolar calendar systems in use.
A Solar year is the time taken by Sun in its passage from one equinoctical point back to same point = 365.242 days. A Sidereal year is time taken for Sun to move from one star, and then come back to same star which is 365.256 days. Solar year is shorter than Sidereal year by about 19 minutes and 50 seconds and is said to be caused by inertial effects. It is called Earth's Precession.
A Lunar year is made up of 12 lunar months and an extra month added periodically to account for extra days. Moon represents our thought or mind, whereas Sun signifies our action (body). Western astrology is based on Sun, whereas Indian astrology or Vedic astrology is based on the Sun and Moon.

Earth (land mass) with curvature looks like the back of a Turtle which, is a good representation of the slowly sliding Earth plates. Scriptures (Varaha, an ancient geographer) classified earth land mass (bhudevi) into seven dvipas and further sub-divided into the varshas, surrounded by seven seas, after deluge or ice age.

Seven location or dvipa: Jambu dvipa (North, Central and Southern Asia - southern part is bharat); Plaksa dvipa (Mediterranean - some include north africa); Saimali dvipa (East Africa - some include west Africa also); Kusa dvipa (Middle east); Kraunca dvipa (Europe); Saka dvipa (South east asia, australasia); Puskara dvipa (East Asia and northern pacific islands - also america); So, India we say for place, ஜம்பூத்வீபே

Rithu ருதௌ Seasons for southern hemisphere:
1 Praana = 4 seconds
1 Vinadi = 6 Praanas = 24 seconds
1 Ghatika (nazhi) = 60 Vinadis = 360 Praanas = 24 minutes
1 Muhurtha = 2 Ghatikas = 48 minutes
1 day = 60 Ghatikas = 3600 Vinadis = 21600 Praanas
One year made up of 6 seasons of 60 days or 360 days. Extra days were treated as divine days.
Later changed to months based on Sun movement along 12 zodiac signs, a month being a period to cross each zodiac. Two months account for one season.

Summer: December Solstice

Winter: June Solstice
Spring: September Equinox

Nakshatras:

Daksha, (may be chaldean astronomer), identified and named 28 stars and all stars are considered as his daughter. The North and South celestial poles do not remain permanently fixed against the background of the stars. Due to precession of the equinoxes, the poles trace out circles on the celestial sphere, with a period of about 25,700 years. North pole identified by polar-star, is part of porpoise-like constellation (stars of Cassiopeia make its tail, Andromeda and Triangulum form its body, and Aries makes its head)
Below 28 stars with tamil and astronomical names are listed. Angle with reference to Aswin are given in degrees. Currently, Aswin rises at 31 Deg on March Equinox.

Egyptians, Phoenicians, Persians, Greeks, Roman, and many cultures began their new year with the fall equinox. Around 1800 years back the day Sun enters Makara Rashi (Capricorn) was coinciding with the day of Uttarayana or Winter Solstice or Surya beginning Northern journey (Northern hemisphere). This happens to be harvest season. It is also Thiruvalluvar new year or early Tamil New Year. start a year with winter or December solstice (Dec 23). Because of Leap year calculation errors, Gregorian new year shifted by 7 or 8 days. Because of earth's precession, Tamil new year shifted by 21 or 22 days.

Mesopotamians and early vedics celebrated around the time of the vernal equinox, March 23 (Current Hindu Saka calendar). Saka era or Shalivahana Sakabda is the vernal equinox of the year AD 78. Later many Indian systems shifted new year from solstice to March Equinox, during the time of Bhadra, Indian astronomer.

Hindu calendar is a collective name for most of the luni-sidereal calendars and Shalivahana calendar in the Deccan States of Karnataka, Telangana, Maharashtra and Andhra Pradesh

Buddhist Era starts on 543 or 544 BC, replaced by Vikrama Samvat calendar which began in 56 BC. Astronomical calculations are based on Kaliyuga start alignment on 3102 BC (by Aryabhatta). There are other eras such as: Vedanga Jyotisa; Gaurabda Gaudiya; and Kolla Varsham.

Year names are:
Surya Siddhantic list starts with Vijaya. Kalacakra calendar in use, 60 year cycle starting with Prabhava, is by Pandita Somanatha of Tibet/Himalayas, in 1027. He further developed sexadecimal system. The earth's axis wobble that causes the precession of the equinoxes is approximately 25,920 years or 432 sixty year cycles. Many ancient sites reflect the number 432 in their alignment to stars and planets and the earths path through space.

Metonic cycle is 19 years or 235 lunar months or approx 6940 days, nearly a common multiple of the solar year and the synodic (lunar) month. With in 19 years, every 8 and 11 are close match. Callippic cycle, a 76-year cycle with a more accurate approximation = 27759 days.
Tamil Solar New year will be on new moon in 2010 and on full moon in 2014.

Note: Indian festival and ritual days have to be recalculated for Auckland, New Zealand 36° 55' S 174° 45' E, based on original data for Ujjain 23° 11' North 75° 47' East . Long time back, patronized by maharajahs, few astronomers have calculated corrections to be applied for all important places in India. After this not much work has been done. Sunrise and Sunset are not observational and based on geometrical calculations. The centre of the Sun's and Moon's disk are used for rise and set calculations. The refraction is ignored. Due to refraction the Sun becomes visible even when it is below eastern or western horizon. Equinoxes are referred as March Equinox (Northern Equinox) and September Equinox (Southern Equinox). During Equinoxes the tilt of the Earth (with respect to the Sun) is 0° and because of it duration of the day and the night are almost equal on Equinox day i.e. 12 hours. These observational data is used to check calculations.
My panchangam and Himalayan academy publishes panchangam for different places. Maharishi Vashistha, Surya siddhanta, Bhaskaracharya, and Tithi Chinatamani all says one thing. Wherever you are, according to the time of that place, take the panchang as seen by drika ganitha as per that place. The "drik ganita” means calculations corresponding to observable reality and used by mypanchang.com, datepanchang, janmabhumi panchang, rastriya panchang. One has to do observation and apply bija samskaram and other corrections. So, panchang is like sky map locating stars and planets and you can not use one city map to navigate in another city.
