A friend from Kolkata once told me the real test of a Durga Puja calendar is whether it gets Saptami and Ashtami right, because those two days are where most printed calendars quietly disagree with each other. 2027 is exactly the kind of year that exposes the disagreement, since the tithi timing genuinely compresses two of the five main days close together.
The main 2027 dates
Durga Puja 2027 runs from Shashthi on October 6 through Vijaya Dashami on October 9. Within that window, Maha Saptami and Maha Ashtami both fall predominantly on October 7, because the Saptami tithi ends and Ashtami begins later in the day, well after the customary morning rituals for Saptami are already underway.
Maha Navami follows on October 8, and Vijaya Dashami, marking Durga’s immersion, lands on October 9.
Why Saptami and Ashtami overlap this year
Each tithi (lunar day) has a precise start and end time that rarely aligns neatly with sunrise. Most years, Saptami and Ashtami each get a full calendar day of their own.
In 2027, the Saptami tithi is short enough, and starts late enough, that it barely spans a sunrise-to-sunrise day before Ashtami takes over, pushing the two into what looks like a single compressed day to anyone tracking only the Gregorian date.
Traditional practice still observes each tithi’s specific rituals (Saptami’s Kola Bou bathing ritual, Ashtami’s Sandhi Puja at the exact junction of the two tithis) even when they share a calendar date, which is why the exact clock time of Sandhi Puja matters more than the date alone in a year like this.
Saraswati Puja and Durga Puja season
Just before the main Durga Puja days, a separate autumn Saraswati Puja is observed around October 7, as part of the same festival season. This is not the more widely known spring Saraswati Puja on Basant Panchami; the distinction between the two is covered in Saraswati Puja 2027.
This site does not sell pujas or rituals. Every date here is checked against the Panchang; where two sources genuinely diverge (as with the exact Sandhi Puja minute, which depends on your city), that is stated rather than papered over.
What are the main Durga Puja 2027 dates?
Shashthi on October 6, Saptami and Ashtami both largely on October 7, Navami on October 8, and Vijaya Dashami on October 9.
Why do Saptami and Ashtami fall on the same day in 2027?
Because the Saptami tithi is short and ends late in the day, leaving little separation before Ashtami begins, so both land on the same Gregorian date this year.
Is the exact Sandhi Puja time the same everywhere?
No. Sandhi Puja happens at the precise junction of Ashtami and Navami tithis, which is a specific clock time that varies slightly by city and time zone.
Is the autumn Saraswati Puja part of Durga Puja?
Yes, in Bengal and neighbouring states it is observed as part of the same Navratri and Durga Puja season, distinct from the spring Saraswati Puja on Basant Panchami.
