There
  are 6 Navarathris in Honour of Divine Mother of our Universe - one for
  each Rithu (season), and this navarathri falling in the sharad rithu 
is  the most important one as it is the one recommended for 
householders.
Navarathri schedule for different parts of the world.
Navaraathri
  austerities begin from October 5, 2013 in India, Gulf countries, European countries and all nations in American continents.
Those living in Malaysia, Thailand, Myanmar, China, Hong Kong, Singapore, Australia, New Zealand, Japan, and Fiji must observe this from October 6, 2013. 
Durga pooja is to be observed
 on October 12, 2013 throughout the world except those living in USA, Canada, and other nations of the American continents who must observe this on October 11, 2013 itself.
Mahaa Navami (Saraswathy Pooja, Ayudha pooja) should
  be celebrated on October 13, 2013 throughout the world - except for those living in USA, Canada, and other nations of the American continents who must observe this on October 12, 2013 itself.
Vijaya Dasami -
There is some confusion in this matter this year.....While Kanchi almanac and some other panchanga scholars opine that Vijaya Dasami also should be observed on October 13th itself in India, Sringeri vidwans and other experts suggest the observance on October 14, 2013.  We are more inclined to side with the Sringeri tradition in this regard since Dasami operates during sunrise of October 14, 2013 and it does not happen until 1:19 p.m. on October 13, 2013. [Dharma shastraic injunctions in this regard suggest that for sukhla paksha dasami related vratas, the reckoning time is sunrise during which time Dasami must operate; if the vratam is about krishna paksha dasami, then we must see on which of those solar days Dasami operates for more time and then take a decision - and it is usual to give preference to the day which has dasami predominating during the night on such occasions if it operates for almost equal duration on both days during krishna paksha....just for your academic interest regarding dharma shastraic injunction of sages in this regard].
So, we leave the observance of Vijaya dasami in India to their respective traditions while I will be giving the traditional Vijaya Dasami Chandi homam poornaahuti done at the end of the Daily Navarathri observance only on October 14, 2013 morning.
In countries of the American continent,  Europe and middle East countries, Vijaya Dasami must be observed on October 13, 2013. (yes, for some regions - like in Europe and in Middle EAst countriesMahaa Navami and Dussera fall on the same day - October 23, 2012; going into the astrological/ astronomical/ panchang sookshma nuances will be beyond the comprehension of most normal devotees who would just like to observe the festivals on the correct dates/ days as per shastric doctrines and so I am not going deeper into this).
For those living in countries to the east of India, Vijaya Dasami must be observed on October 14th, 2013.
Methods of celebrating Navaraathri.
It
  is traditional to keep "Kolu" - an arrangement of dolls during  
Navaraathri. This is to signify that Our Divine Mother resides as Inner 
 Soul in all Forms. Some people make the arrangement in such a way that 
 the various steps of the kolu represent the Order of Evolution - like  
keeping invertebrates and such other forms of lives in the bottom step, 
 keeping dolls representing human life in the middle of the kolu steps, 
 and keeping dolls representing Divine Legends, Dasa Avataars, etc. on  
the top most step of the kolu arrangement. It is traditional to keep 5  
rows (to represent Five Elements of Life), 9 rows (to represent the Nine
  Forms of Divine Mother), 11 rows (to represent the 11 forms of Lord  
Rudra), 13 rows (one in Honour of each chapter of Durga Sapta Sati), or 
 15 Rows (one in Honour of each syllable of Shri Vidhya 
panchadasaakshari  mantra) as per one's convenience; traditionally, 
people avoid arranging  the kolu in 7 rows for sentimental reasons 
(there is a belief that such  an arrangement in 7 rows might affect 
financial prospects).
I  request all our members to 
perform simple worships as per their  convenience during the Navarathri 
period and become recipients of Divine  Grace. This is a period when we 
Celebrate our Universal Mother - so,  that joy should be there in our 
minds when we observe this austerity (we  should not be unnecessarily 
tensed or make this too complicated with  too many taboos! One does not 
think of protocols when approaching one's  mother - but just go with the
 moment with unbounded joy and affection;  such should be our attitude 
when we worship Our Universal Mother during  this period - assuming we 
are all Her Children and we are invoking Her  Presence in our homes - 
celebrating this with affectionate respect and  joy).
Recital
 of Lalitha Sahasranaamam, Dasa Mahaa vidhya  sthothrams, simple Devi 
sthothrams, Abhiraami Andhaadhi, Lalitha  Anubooti, Soundarya Lahiri, 
Dugra Sthothram, Chandi Path (Durga  Saptasathi), etc. can be auspicious
 during this period.
During  this period, we should 
consider all women as Forms of Divine Mother and  treat them with 
courtesy and respect. One who observes the Navarathri  austerities 
intensely, but insults women knowingly/ unknowingly does not  get the 
benefit of the austerities. Remember this, and treat women  (including 
those in your own family) with affection and respect [Ideally  that 
should be the case always! Because Shastras say that where  virtuous 
women are honoured, Divine Grace visits even in an uninvited  manner! 
This is the reason why women should take special care to  safeguard 
their basic dignity, be affectionate and gentle in dealings  with family
 members, avoid letting corrupting thoughts/ behaviour  patterns enter 
their life styles, etc. in an attempt to maintain their  Divine nature 
that is intrinsic to them; All higher forms of lives  spring from the 
feminine gender of the species, and a virtuous woman is a  living Form 
of the Universal Mother - and can be a source of happiness  and Grace to
 herself and to everyone who is blessed enough to move with  her).
Those
 who have Tulsi plant in their houses, can offer  prostrations to that 
Divine Plant and pray for prosperity and Divine  Grace in its vicinity. 
(All the Holy Rivers are in subtle forms in the  roots of the tulsi 
plant; All Divine Forms are manifest in the middle  portion of the Tulsi
 plant, and All Vedas and Holy Scriptures are  manifest in the tips of 
the Tulsi plant, as said in the Puranas).
Offering  
Go-Poojaa (prayers to Cow visualized as embodiment of all Divinities)  
on Fridays and Tuesdays of Navarathri period can give unlimited merit.
It
  is also auspicious to read a small portion of Divine Legends that  
depict how the Gracious and Kind Mother Manifested in Angry Forms to  
annihilate all enemies to peaceful life on Earth every night during this
  navaraathri period, and invoke such Manifestation of Power in our 
lives  also to annihilate all our enemies (both intrinsic like anger, 
greed,  laziness, and ignorance within us, and our external enemies/ 
unruly  elements who try to disturb peaceful and gentle citizens in the 
society  unnecessarily).
Recital of Chandi Paaraayanam 
is a powerful  remedy not merely for our families but for ensuring peace
 in the land  where we live in. In fact, if austere persons of Faith 
keep reciting the  Chandi Path and Shri Rudram regularly, and if there 
are many of them in  a land, shastras proclaim that the elements of 
nature's Fury like  floods, pestilence, droughts, etc. will never harm 
that land and  prosperity will rein in that land. So, it is partly our 
duty as  Universal Citizens to offer special worship to Divine Mother 
during this  period and pray for relief to all the distressed souls who 
have been  harassed much by the floods in Northern parts of our blessed 
land, and  also pray for peace throughout the world in these troublesome
 days where  you can never read a newspaper without coming across some 
inauspicious  event/ mishap in one corner or other of the earth.
SPECIAL WORSHIPS AT MY PLACE DURING NAVARATHRI.
As
  usual special worships will be performed at my residence in Chennai in connection
  with Sharada navaraathri from October 5, 2013 to October 14, 2013. 
We  will be offering poojas and homams for Universal welfare daily during these days, and those 
who  are interested in sponsoring the austerities are welcome to do so.

morning  till night.....Ganapathy homam, Laghu chandi homam, 
recital of  Devi Mahaatmyam, Lalitha Sahasranaamam, Soundarya Lahiri 
sthothras, Dasa Mahaa  Vidhya japams, Select verses from Devi 
Bhagavatam,  veda mantra chants  etc.) is US$80(US  Dollars seventy five only). Resident 
Indians might offer Rs.4500- (rupees four thousand five hundred only 
for the same). We are not restricting participation  in the daily 
homams/ austerities this year. Those who wish to be  part-sponsors for 
more than one day's rituals are also welcome to do so.
Mahaa
  chandi homam is planned on October 14, 2013 on Vijaya Dasami day. The  
part-sponsorship for this Mahaa chandi homam on October 14, 2013 is  
US$400 (US Dollars four hundred only).
To enable persons who are interested in taking part in some form of prayers at our place but are unable to afford the part-sponsorships, this year we have decided to offer the following special poojas at affordable sponsorship rates:
1) Durga Sookta, Lalitha Sahasranaamam paaraayanam, and Durga Sapta Slokhi paddathi deepa pooja for general welfare and removal of planetary afflictions in the evenings - US$15 (US Dollars fifteen only).  Part-sponsors of the day's austerities are automatically included in this - so they need not register again for this performance in the evening. 
2) Saraswathy kavacha paaraayanam and other special chants on Vaak Devi from Yamala tantraic literature to improve general intelligence and promote academic prospects on Saraswathy Pooja day - US$15 (US Dollars fifteen only). This is recommended for those who wish to do aksharambam for their kids this year on Vijaya Dasami.
You can select your option of special worships from the drop=down menu given below at the end of this write-up.
Even
  those who are unable to offer sponsorships for these rituals need not 
 feel let down; prayers are offered for Universal Welfare at the end of 
 each day's austerities, in addition to the prayer for specific special 
 sponsors, and the prayer for Universal Welfare covers everyone -  
including you!
May Divine Mother Bless us all. 
 
Blessed be.
