I have posted blogs on the importance of performing Tarpana ((Oblation to Ancestors)- Mahalaya Amavasya.
Some more posts are on Sandhya Vandhana in two parts and  one audio.
The Tharpana Mantras with basic instructions are given below.

Audio Follows.
Post on ‘Sankalpa’, Sanskrit names for performance of Daily Routines including
SandhyaVandana,Months,Rtus,Pakshas,Manvantaras,Nakshatras follow-with Tamil Equivalents.
I will post for Rik , Sama Veda and Shukla Yajur Veda.
In performance of Tharpana, some wear marks on the forehead and some not.
It is better to follow what has been followed at your homes.
As I mentioned in another blog, Tharpana ,Sraddha are to be performed only after Noon,after performing Madyanhika and Brahma Yagnam.
As a matter of fact Brahma Yagnam is to be performed Daily
.
It is sanctioned in the Sastras that the Sraddha or commitment to performing these Duties are important and not throwing away money to ease Conscience.
Food is to be cooked at Home by the wife/Daughter and not by caterers or getting some one to cook at Home.
It is for your parents.
Physical contribution is necessary.
It is also stated that The Brahmanas who come to Srardha are to be well versed in The Vedas and they are to be fed.
Now a days one does not get them and even if one gets them they do not know The Vedas to be called a purohits(Please read my blog on Acharya,Guru and Purohita).
In the absence of a suitable and qualified Brahmana, I suggest one feed a really needy, caste does not matter, but one should be of good habit, not a Drunkard,way ward and generally uncouth.
They can be given new clothes which they can use, not necessarily Dhoti and Angavastram.
The same can be followed during the Srardha for Women , by giving Sari or chidudhar as they prefer.
I am aware those who call them Panditas objecting to this.
But this is what I have been doing for the past 30 years, criticisms notwithstanding.
Unfortunately for them I read the Sastra texts.

While going through your article as well list of important days of the year I am surprised to see the date of Pithru tharpanam, which falls on Friday, 14th August, 2015. How could such an important day could be forgotten?
August 14 is Amavasya.Tharpana has to be performed.Thithi has nothing to do with Day.For Fridays Akshata has to taken with Ellu.
while starting what natchatra thidi detail only we require others are in books
Nowadays people resort to internet and rely less on Books
Please will you give the Tamil translation of the Mantras to actually know the meaning.
My first cousin (periappa’s son) agrd 90 yrs died on Dec 3. Most of the dayadi’s like me are above 78 yrs and due to failing healh unable to go to cousin’s son’s home to offer 10th day tharpanam. So, I will offer the tharpanam at home. I’m not calling any vadhyar. Due to knee problem, will sit on a small stool and offer the tharpanam water at back of house. I believe the 10th day tharpana manthram is somewhat different to what we offer to parents on Amavasya days. One of my friends age 86 suggested to utter “Gothram of dead person, Name sharmana, mama brathaya prethaya followed by 1) Prathame Aahyam Vasodakam Dadami – 3 times water in reverse thro a piece of cloth 2) Dweethiye Aahyam Vasodakam Dadami – – 4 times water in reverse thru a piece of cloth and so on till 10th day – 13 times. Is this correct? Also, is it necessary to do the usual Sankalpam. Pls advice how to close the tharpanam. Thanks.
In Tharpana and Sraddha, the faith, the disposition to perform them is more important.
It is alright if one offers Tila and water as a Tharpana.
You need not think about the 10th day mantra as it is not relevant in regular Tharpana.
I shall post a detailed article on the conditions when one can not offer regular Tharpana, as many have asked me about this.
In your specific case, considering your age and health, it is enough if you offer Tila and water with the mantra ‘Udhiratdham avara…’the first Tharpana Mantra 3 times each for each Pitru or one for one Pitru (3+3=6), changing the name for Pitru, Pitha maha, Prapitamaha and Mathru Vargam
If this is difficult, you may offer utter simply sarvam Krishnapana masthu’ praying the Pitrus( you may chant the Gothras and nama)
Normal closing of the Tharpana is as per the regular procedure, with Yesham Na maatha Na Pithu’etc…
In your case this is not necessary.
There is the exemption after 60 and or due to illness, the regular Tharpana is waived with the procedure I have mentioned.
One word of caution, in all the cases the desire to perform Tharpana is important and the method I have suggested should not be misused as a justification for avoiding detailed Tharpana.
