Hindu calendar......(1)

How the Hindus remember their calendar? A very simple method had been evolved and it continues even after many thousands of years, from father to son and from a Teacher to his desciple, generations after generations by oral recitation. The method is like this:
Before performing certain day-to-day duties ( including morning bath), a declaration ( Sankalpa) is made. It runs like this:-
1. Salutations to the Gurus ( Acharyas).
2. Blessings of God invoked.
3. Prayer ( to Lord Vishvakshenar) for carrying out the duties without any hindrance.
Now the recitation of the calender:
!. By the will of Lord Mahavishnu (VishnorAgjaya)
2. Now running( Pravarthamanasya)
3. During the period of First Brahma( Adhya Brahmanaha )
4. In his second half (Dwitheeya Parardhe)
5. In Swethaswaraha Kalpam ( swethasvaraha kalpe )
6. Vaivasvathamanvanthram ( Vaivasvathamanvanthare)
7. In Kaliyugam (Kaliyuge)
8. in the first part of ( the above) ( Prathamepade)
Now, the geographical location of the performer
1. In Bharatha Varsham, In the Island of Jambu ( Jambudweepe,Bharatha Varshe)
2. In the continent of Bharatham (Bharatha Khande)
3. In the Era Saka (Sakabthe)
4. In the South of Holy Mountain Meru (Meroho Dhakshineparsve)
5. In Presently Running(Asmin Varthamane Vyaharike
6. In the period of Sixty Years Beginning From Prabhava( Prabhavadeenam Sashti

7. In the year Vyaya( Vyaya Nama Samvathsare)
8. In the Southern Phase of the Sun(Dakshinayane)
9. In Summer(Krishmaruthow)
10.In the month of Kataka(Katakamase)
11.In the Full Moon phase(Shulapakshe)
12.On the auspicious day of Fullmoon (Pournamasyam Shubha Thithow)
13.On Wednesday(Sowmyavasara Yukthayam)
14.On the Day of Shravana Star(Shravana Nakshathrayukthayam)
15.On Yoga (Vishnuyoga Vishnu Karana, Shubha Yoga Shubha karana)
16.On Karana (as above)

Finally the declaration of the duty to be performed is done

That is how the calendar beginning from billions and billions of years ago is kept current till this day. This calculation is very near to the present day scientific calculations. We are the proud owners of such scientific knowledge.

So please follow this method to keep this alive and transfer this knowledgeto the posterity.
