Date Of Construction

In Indian system the “Tithi”(Hindi Date) plays a very important role in determining the auspiciousness of time or day for a particular activity. The tithi prevailing on the day of construction has to be auspicious to harness the good effects of nature.If we add 4 to the current tithi number and multiply by 2; to this number add letters of the name of owner.Divide the sum by 3. If the remainder is 1 or 2 then the construction on that day will result all round benefits and if remainder is 3 then it will cause inauspicious results to the owner.
Example
If a owner Ram Kumar want to begin the construction on Panchami tithi, then calculations will be as follows
Current Tithi=5
Letters in the name of owner=8
Formula=(((5+4)x2)+8 )/3=26/3
Remainder=2
Result=Auspicious

Age of House

It sounds amazing that age of house can be calculated. In modern era the construction is done at abnormally alarming rate. Despite using new technology It is often seen that houses which were built many decades before are still in a better position than the newly built house as they require renovation less frequently.

Formula-
To know the age of house multiply the built up area by 8 and divide it by 120. The remainder indicates the age of house. It is advisable that it should be above 60. The lesser it is, the more frequently the house will demand renovation.
For Example
The area of floor is 20fx38f
Formula =(20x38)x8/120=(760x8)/120=6080/120=Remainder is 80
This is above the average.

Rahu Kaal

Rahu is a planet of separation. It is rahu who was given a boon that he will cause eclipse from time to time. It is a natural malefic planet. The kaal means “the period of time”. It is believe that certain duration of each day is inauspicious which is rule by Rahu. During this time one should avoid any auspicious action such as investments, business transactions, journeys and medical treatments. It is believed that work done during this period does not bring successful results..In hindu jyotish the day begins when the sun rises. The difference between time of sunset and sunrise indicate the length of day called as Dinmaan. Divide the Dinmaan by 8. We get 1/8 th portion of a day. Now for various days the portion ruled by rahu is given below.
For Sunday , the 8th portion from the sunrise is Ruled by Rahu
For Monday the 2nd portion is called Rahu Kaal
For Tuesdays - 7th portion is Rahu Kaala
For Wednesday - 5th portion is Rahu Kaala
For Thursday - 6 th portion is Rahu Kaala
For Friday - 4 th portion is Rahu Kaala
For Saturday -3rd portion is Rahu Kaala

For Example

For Monday if the sunrise in Delhi is at 6.30am and sun set is 5.50 pm, then the Dinmaan will be (5.50pm-6.30 am) of 11 hrs and 20 mints equivalent to 680 mints. Divide it by 8, we will get duration of each portion of 85 minutes (1 hr & 25 mints.).
Portion 1 from sunrise(6.30) to 7.55 am
Portion 2 from 7.55 am to 9.20 am
Portion 3 from 9.20 am to 10.45 am
Portion 4 from 10.45 am to 12.10 pm
Portion 5 from 12.10 pm to 1.35 pm
Portion 6 from 1.35 pm to 3.00 pm
Portion 7 from 3.00 pm to 4.25 pm
Portion 8 from 4.25 pm to 5.50 pm
As per rule on Monday 2nd portion is rahu kaal. Therefore from 7.55 am to 9.20 am is rahu kaal
