September 2027 is the crowning month of the Malayalam year. It carries Kerala through the final days of Chingam into the fresh month of Kanni, and it holds the state’s most beloved festival, Onam, alongside the devotional intensity of Ganesh Chaturthi, two Ekadashi vratams, the twilight grace of Pradosham, and the ancestral close of Amavasya. For anyone searching for the Malayalam calendar 2027 September, this month is a bridge between the harvest joy of Chingam and the inward turn of Kanni, and it is filled with observances that connect family, food, prayer, and community.
This guide gives you a verified day-by-day table, clear explanations of each major day, and practical ways to use the calendar at home with balance and respect for tradition.
September 2027 Malayalam Calendar: Day-by-Day Table
September 2027 runs from Chingam 15 to Kanni 13 in the Malayalam calendar (Kollavarsham 1203). The month of Kanni begins on Saturday, 18 September 2027, with the Sun entering the sidereal sign of Kanya (Virgo) on 17 September at 13:58 IST . The table below organizes the major festivals, vratams, and observances in a simple, readable format.
A note on dates: Tithi-based observances such as Ekadashi, Pradosham, and Amavasya depend on sunrise, sunset, and moonrise in the local Kerala Panchangam. Nakshatra-based days such as Thiruvonam follow the star period. Families in Kochi, Thrissur, Palakkad, Kozhikode, or any other district should always cross-check with the Panchangam traditionally followed in their household or local temple.
Onam 2027: Atham on 3 September and Thiruvonam on 12 September
Onam is the heart of September 2027. The ten-day festival begins with Atham on Friday, 3 September, and culminates in Thiruvonam on Sunday, 12 September . Thiruvonam is the day when the Thiruvonam nakshatra prevails in the Malayalam month of Chingam, and it is the main day of Kerala’s harvest festival .
Onam celebrates the homecoming of the mythical king Mahabali, and it is marked by Pookalam (flower carpets), Onasadya (the grand vegetarian feast), Vallam Kali (snake boat races), and family gatherings. In 2027, the main Onam days fall in the second week of September, with First Onam (Uthradom) on 11 September and Thiruvonam on 12 September .
For Kerala families, Onam preparations begin well in advance. Homes are cleaned, new clothes are bought, and the sadya menu is planned. The Onasadya traditionally includes rice, sambar, avial, thoran, pachadi, kichadi, injipuli, pappadam, and payasam, served on a banana leaf. The Pookalam is laid fresh each morning, with the design growing more elaborate as Thiruvonam approaches.
At home, the day of Thiruvonam begins with a clean prayer space, a lit nilavilakku, and a simple prayer for family well-being. The sadya is offered as nivedyam before the family eats, and the afternoon is spent visiting relatives and friends. Onam is not a day of strict fasting; it is a day of abundance, gratitude, and togetherness.
Ganesh Chaturthi on 4 September 2027
Saturday, 4 September 2027, is Ganesh Chaturthi, the birth of Lord Ganesha . In Kerala, Ganesh Chaturthi is observed with prayers at home and visits to Ganesha temples. The festival is not as elaborate as in Maharashtra, but it holds deep significance for families who begin new ventures, children who start their education, and devotees who seek the removal of obstacles.
At home, clean the pooja area and place a Ganesha image or idol in the prayer space. Light a nilavilakku, offer flowers, coconut, banana, and durva grass where available. Chant a familiar Ganesha mantra, such as “Om Gam Ganapataye Namaha,” and offer appam or unniyappam as nivedyam. Some families observe a partial fast until the evening pooja, while others take a simple vegetarian meal.
The ten-day Ganesh festival continues until Anant Chaturdashi on 14 September, when the idol is ceremonially immersed. Families who keep a Ganesha idol at home for the ten days should follow the customary visarjan (immersion) procedure with respect and care for the environment.
Parivartini Ekadashi on 11 September and Indira Ekadashi on 26 September
September 2027 contains two Ekadashi vratams. The first is Parivartini Ekadashi on Saturday, 11 September, and the second is Indira Ekadashi on Sunday, 26 September . Both are dedicated to Lord Vishnu, and both are observed with fasting, prayer, and the lighting of a nilavilakku.
Ekadashi is the eleventh tithi of the lunar fortnight. A strict observer may avoid rice, wheat, pulses, and regular meals, while others take fruit, milk, banana, or a simple vratam meal permitted by family tradition. Onion, garlic, meat, and alcohol are commonly avoided.
A simple home observance begins with an early bath and cleaning of the prayer space. Light a nilavilakku before an image of Mahavishnu or Krishna, offer tulasi leaves, flowers, and clean water, and recite a familiar Vishnu prayer or “Om Namo Narayanaya.” Offer banana, coconut, or aval as nivedyam, and complete the parana on Dwadashi according to the local Panchangam. The first Ekadashi falls during the Onam season, and families may combine the vratam with the festive atmosphere, while the second falls in Kanni and offers a quieter day of reflection.
Pradosham on 13 and 27 September 2027: Shiva’s Twilight Grace
Monday, 13 September, and Monday, 27 September, are both Pradosham days . Pradosham is the thirteenth tithi of the lunar fortnight and is observed during the twilight period, a time considered especially sacred to Lord Shiva and Parvati.
At home, clean the worship area before sunset, light the nilavilakku, and remember Shiva and Parvati. Offer water, flowers, and bilva leaves where available, and chant “Om Namah Shivaya” calmly. Some devotees fast until deeparadhana, while others take fruit or a light meal. The first Pradosham falls on the day after Thiruvonam, and the second falls in the new month of Kanni, creating a continuity between the festive and the contemplative halves of September.
Masa Shivaratri on 28 September 2027
Tuesday, 28 September 2027, is Masa Shivaratri, the monthly Shivaratri . It is a quieter observance than Maha Shivaratri but carries the same spirit of self-discipline and Shiva remembrance. A simple lamp offering, the chanting of “Om Namah Shivaya,” and a vegetarian meal are sufficient for most households. Some devotees fast until the evening pooja, while others take fruit and milk during the day. The day falls just before the new month of Kanni’s first Amavasya, and it offers a moment of pause before the ancestral observances of 30 September.
Kanni 1 on 18 September 2027: A New Malayalam Month
Saturday, 18 September 2027, marks the first day of Kanni, the Malayalam month that corresponds roughly to mid-September to mid-October. The Sun enters the sidereal sign of Kanya (Virgo) on 17 September at 13:58 IST, and the month begins the following day .
The shift from Chingam to Kanni is a seasonal marker. It signals the end of the Onam harvest and the beginning of the post-monsoon season. For Kerala families, the day is a gentle reminder to clean the prayer area, light a lamp, and begin the new month with gratitude. Some households prepare a simple payasam or a vegetarian meal to mark the occasion. Kanni is also the month of Pitru Paksha, the fortnight of ancestral remembrance, which begins after the full moon and leads to Ashwin Amavasya on 30 September.
Pournami on 15 September 2027 and Sree Narayana Guru Jayanthi
Wednesday, 15 September 2027, is Pournami, the full moon day . In Kerala, Pournami is observed with a simple vratam, lamp worship, and offerings of payasam or fruit. The full moon is linked to mental peace and family harmony, and the evening is often marked by a quiet pooja at home.
The same day is Sree Narayana Guru Jayanthi, a Kerala public holiday honouring the social reformer and spiritual leader Sree Narayana Guru . Guru Jayanthi is observed with prayers at Sree Narayana Guru temples, community programmes, and acts of service. For many Kerala families, the day is a reminder of the Guru’s message of equality, education, and spiritual unity. The convergence of Pournami and Guru Jayanthi gives the day a double significance: it is both a full-moon observance and a celebration of Kerala’s reformist heritage.
Sankashti Chaturthi on 19 September 2027
Sunday, 19 September 2027, is Sankashti Chaturthi, a vratam dedicated to Lord Ganesha . The observance is connected with the Krishna Paksha Chaturthi and the local moonrise, so the fast is not completed merely at sunset. Devotees break the fast after viewing the moon and offering prayers to Ganesha.
Observers may take fruit, milk, or a light vratam preparation during the day. At home, clean the pooja area, place a Ganesha image in the prayer space, light the nilavilakku, and offer flowers, coconut, banana, and durva grass where available. Chant a familiar Ganesha mantra, and offer appam or unniyappam as nivedyam. The moonrise timing should be checked in the local Panchangam, as it varies by district.
Ashwin Amavasya on 30 September 2027: New Moon and the Start of Navratri
Thursday, 30 September 2027, is Ashwin Amavasya, the new moon day of the Ashwin month . In Kerala, Amavasya is associated with ancestral remembrance, and the Ashwin Amavasya that falls at the end of Pitru Paksha is especially significant. Families offer bali and tharpanam to departed ancestors, and the day is marked by prayer, charity, and quiet reflection.
The same day marks the beginning of Sharad Navratri, the nine-night festival dedicated to the Divine Mother . Navratri begins with Ghatasthapana, the ceremonial installation of the kalash. In Kerala, the Navratri season is observed with prayers at Devi temples, especially at Chottanikkara and Kodungallur, and with the reading of the Devi Mahatmyam. Families may begin the nine-night observance with a simple lamp offering and a prayer for the well-being of all.
How Kerala Families Use the September 2027 Malayalam Calendar at Home
The Malayalam calendar is most useful when it becomes a practical guide for daily life. Here are a few simple ways to use the September 2027 calendar in a Kerala household:
Keep a printed or digital copy in the pooja area. A single glance at the month helps families remember Onam, Ganesh Chaturthi, the Ekadashis, and the Kanni transition without last-minute confusion.
Check the local Panchangam for tithi timings. Onam’s Thiruvonam is nakshatra-based, and the Ekadashi and Pradosham timings can shift by district. Following the family Panchangam avoids confusion.
Plan Onam preparations early. The Pookalam, sadya, and family visits are best organised well before 12 September. Shopping and cooking can be spread over the first week of the month.
Use Ganesh Chaturthi to begin something new. The day is traditionally auspicious for starting education, new ventures, or a family project. A simple Ganesha prayer and a shared appam are enough.
Mark the Kanni transition with a family reset. On 18 September, clean the prayer area, light a lamp, and begin the new month with gratitude. The Pitru Paksha that follows is a time for ancestral remembrance and simple living.
Balance tradition with health and work. Fasting should never come at the cost of health. Working professionals can observe Ekadashi with fruit and milk rather than a full fast. The spirit of the vratam is devotion and self-discipline, not rigidity.
