Dear all,

 

When a fellow bhAgavata friend asked the way DwAdasi PAraNai

time has to be calculated, aDiyEn replied back as an algorithm

(just for a surprize and some amount of fun) since that bhAgavata

is in the software field. Thought of just sharing it for

time being ....

 

/* Algorithm for determining the DwAdasi PAraNai Time-Range */

 

TSDT = Time Span of DwAdasi Thiti from Sun-Rise, converted

to hrs-mts scale. TSDT takes values from Zero and upwards

/* One nAzhi = 24 mts; 5 nAzhi = 2hrs */

 

H = Time Span of HarivAsaram converted to hrs-mts scale.

/* H may take values from Zero and upwards,

but always less that TSDT. H is Zero in many cases,

but not always Zero. Important to know its value,

though it would be usually small. Basically, one

shouldn't eat during the HarivAsaram time period. */

 

ST = Sun Rise Time.

 

/* TSDT, H and ST to be obtained from Calendar */

 

PT = PAraNai Time Range- A Real-valued Set.

 

/* 6 nAzhi = 2hrs and 24mts = 144 mts */

 

If (TSDT >= 144 mts) then PT = [sT+H..ST+144];

 

/* PT is anytime between ST+H to ST+144 mts ;

H won't take values as large as 144 mts*/

 

Else If (TSDT > 0 mts) then PT = [sT+H..ST+TSDT];

 

/* Here, TSDT is less than 144 mts, but greater than Zero.

PT is anytime between ST+H to ST+TSDT */

 

Else PT = [sT+H..ST+144];

 

/* Here,TSDT is Zero ie.even before Sun-Rise, DwAdasi Thiti

got over; It occurs very rarely. PT is same as that of

the first case */

 

/* End of Algo */
