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

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 natural calamities in various parts of the world, 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.
