RAHU KALAM;
According to Vedic astrology, certain parts of the day, called Rahu Kalam, are inauspicious periods and one should not undertake any auspicious work during these periods - especially any new undertaking.
Rahukalam differs from place to place depending on Sun-rise & Sun-set time. The day duration from Sun-rise to Sun-set, at a particular location, is divided into eight equal parts. There is no Rahu Kalam during the first period of any weekday. On Monday it falls on the 2nd period, Saturday 3rd period, Friday 4th period, Wednesday 5th period, Thursday 6th period, Tuesday 7th period & Sunday 8th period.
The following are the details of the Rahukalam (also known as rahukal or rahu kal) periods in in operation during the various week days. This is based on 6:00 AM local Sun-rise time and 6:00PM local Sun-set time. If the Sun-rise and Sun-set times are different, you can take the Day duration, divide it in to 8 equal parts and apply the above given formula.
Since the Raahu Kalam is dependent on the Sun-rise and Sun-set times of your particular location, you must calculate it for each day using the bellow method.
Your local Sun-rise & Sun-set times are usually given in the local news papers.
Raahu Kaalam Calculation
Week day
Example 1:Sunrise 6:00 a.m.Sunset 6:00 p.m.1/8 of Day = 90 minutes
Example 2:Sunrise 5:58 a.m.Sunset 8:14 p.m.1/8 of Day = 107 minutes
Example 3:Sunrise 6:36 a.m.Sunset 6:10 p.m.1/8 of Day = 87 minutes

Yamagandam
Like Rahukalam the following periods known as Yamagandam during which it is considered to be inauspicious to start any important work.
Monday ------10-30 --AM --to --12 -00--PM
Tuesday ------9-00 --AM --to--10 -00---AM
Wednesday ---07-30 --AM --to 09--oo-- AM
Thursday----- 06-00-- AM -to- -07-30 ---AM
Friday---------03-00 PM --to---4-30 -----PM
Saturday ------1-30 PM ---to---- 03 -00---PM
Sunday-12 -00 PM TO 1-30 PM
According Hindu Astrology, there are seven days in a week viz., from Sunday to Saturday. Each day is being ruled by a particular planet and has its own ruling deity. The ancient texts says that ruler of the day is prescribed that is as under:
Sunday is ruled by Ravi
Monday is ruled by Chandra
Tuesday is ruled by Kuja
Wednesday is ruled by Budha
Thursday is ruled by Guru
Friday is ruled by Sukra
Saturday is ruled by Saturn
In addition to the above, the ancient rushies have given equal importance to Rahu and Ketu. However, they did not give any specific day for them as they treated Rahu and Ketu as nodes. However, Rahu and Ketu will be given one and half hours time in a day resulting three hours for Rahu and Ketu.
Out of 24 hours time, if we deduct three hours (one and half-hours for Rahu and another one and half-hours for Ketu) comes to 21 hours, which is shared by the seven planets. However, Rahu and Ketu have been given equal powers by rushies. If we calculate the time, the total time given to Rahu and Ketu in a week is 21 hours. Let us see how to calculate.
Rahu Kalam = 1.30 x 7 = 10.30
Yama Kalam = 1.30 x 7 = 10.30
Total time: 21.00 hours
For calculating Rahu Kalam and Yama Kalam, from Sun rise to Sunset will be divided into 8 equal parts.
The first part will become the day of the ruler. For example, if we take Sunday, the first part is Ravi and hence, the day is ruled by Ravi. After deducting the first part of the day, the time of Rahu Kalam is calculated within the seven parts. For easy calculating of Rahu Kalam, we remember the following sentence.
'Mother Saw Father Wearing The Turban on Sunday'
If we want to calculate the Rahu Kalam, if the Sunrise is 6am, as we discussed earlier, leave first one and half hours. The rest of the seven can be divided into seven parts. On any day, the first part is called Rahu Kalam.
Ex. Mother = Monday - 7.30 to 9.00amSaw = Sunday - 9.00 to 10.30amFather = Friday - 10.30 to 12.00 noonWearing = Wednesday - 12.00 to 1.30pmThe = Thursday - 1.30 to 3.00pmTurban = Tuesday - 3.00 to 4.30pmSunday = Sunday - 4.30 to 6.00pm
Therefore, before calculating the Rahu Kalam one has to take into consideration of the Sun rise time.
