Timing is everything. If you're planning a puja, a fast, or just trying to figure out when the neighborhood temple is going to be packed, knowing exactly when is Ashtami 2025 matters more than just glancing at a wall calendar. Most people assume there’s just one big day. Truthfully? There are dozens of them.
Every lunar month has two Ashtamis. One falls in the waxing moon (Shukla Paksha) and one in the waning moon (Krishna Paksha). But honestly, most of us are looking for the "big" ones—the ones connected to Durga Puja or Krishna Janmashtami.
Let's cut through the confusion of the Hindu lunisolar calendar.
The Big One: Maha Ashtami 2025
For most people asking about this date, they’re thinking of Durga Puja. This is the peak of the festival. In 2025, Maha Ashtami falls on Wednesday, October 1, 2025.

It’s a huge day. The atmosphere is electric. You've got the Pushpanjali in the morning, where everyone wears new clothes and tries not to faint from the smell of incense and the heat of the crowd. Then there’s Sandhi Puja—the precise window where Ashtami ends and Navami begins.
This specific transition is spiritually heavy. It marks the moment Goddess Durga engaged in the final battle with Mahishasura. If you're planning to attend a ceremony, the Tithi (lunar day) doesn't always align perfectly with the sunrise-to-sunset clock we use in daily life.
According to the Drik Panchang, the Ashtami Tithi for the Shardiya Navratri period actually begins on the evening of September 30 and carries through the day on October 1. This overlap is why you might see some temples starting rituals at what feels like "off" hours.
Krishna Janmashtami and the August Dates
Wait. You might be looking for the birth of Krishna.
Krishna Janmashtami also happens on an Ashtami—the eighth day of the dark fortnight in the month of Bhadrapada. In 2025, this falls on Saturday, August 16.
If you're in Mathura or Vrindavan, or even just heading to a local ISKCON temple, this is the date that's circled in red. It’s a midnight celebration. People fast all day. It’s intense, loud, and beautiful.
But why the discrepancy? Why are there so many? Basically, the Hindu calendar is lunar. It doesn't play nice with the 365-day Gregorian year. That's why the dates shift by about 11 days every year unless there's a leap month (Adhik Maas) involved to pull things back into alignment with the seasons.
Breaking Down the Monthly Ashtami Schedule for 2025
Maybe you’re looking for Masik Durgashtami. These are the monthly observances for devotees of Goddess Durga.
Honestly, trying to memorize these is a headache. Here is how the 2025 calendar actually looks for the Shukla Paksha Ashtamis:
In January, it hits on the 7th. February is the 5th. March follows on the 7th. April’s date is the 5th, which is also significant because it falls during Chaitra Navratri. This is often called Chaitra Durga Ashtami. It’s the spring version of the big autumn festival. If you live in Northern India, this is when you’ll see the Kanya Pujan—the ritual where young girls are worshipped as personifications of the Goddess.
May 2025 sees Ashtami on the 5th. June is the 3rd. July is the 3rd. August is the 1st and then again on the 31st because of how the lunar cycle overlaps the calendar month. September is the 30th (leading into the October mega-festival). October is the 30th. November is the 28th. December ends the year on the 27th.
That’s a lot of fasting if you’re a strict devotee.
Radhashtami and Other Special Mentions
Beyond the "Big Two," there's Radhashtami. This is the birth anniversary of Radha, the consort of Krishna. It’s a big deal in the Braj region.
In 2025, Radhashtami is observed on August 31.
It follows exactly 15 days after Krishna Janmashtami. If you’re a follower of Vaishnavism, this day is just as important as the mid-August celebrations. The vibe is different, though. It’s more focused on Bhakti and the softer, more devotional aspects of the faith.
Then you have Sheetala Ashtami, which happens after Holi. In 2025, this will be on March 22. This is a quirky one. It’s dedicated to the Goddess Sheetala, who is associated with curing smallpox and other heat-related illnesses. The tradition here is unique: you don't light a fire in the kitchen. You eat stale food (Basoda) prepared the day before. It sounds weird to the uninitiated, but the logic is rooted in ancient seasonal health practices as the weather transitions from cool spring to scorching summer.
Why the Timing Sometimes Seems "Wrong"
You’ll see different dates on different websites sometimes. It’s not necessarily a mistake.
It comes down to the Udaya Tithi.
In Vedic astrology, the day is often defined by which Tithi is prevailing at the moment of sunrise. If Ashtami starts at 10:00 AM on Monday and ends at 9:00 AM on Tuesday, Monday is technically the day of observance for some, while others might look at the specific Muhurta (auspicious window) for a specific ritual.

For example, if a fast is meant to be broken at the end of the Tithi, and that happens at 2:00 AM, you’re looking at a very late night.
Practical Tips for Planning Your 2025 Observances
If you're planning a trip to Kolkata for Maha Ashtami or heading to Mathura for Janmashtami, book your travel now. 2025 is expected to see massive crowds as domestic tourism in India continues to break records.
- Check the Tithi Endings: Don't just look at the date. If you're doing a specific puja, look for the Sandhi Puja time. In 2025, for the October festival, this happens in the transition window between Oct 1 and Oct 2.
- Kanya Pujan Logistics: If you're doing Chaitra Navratri (April 5) or Shardiya Navratri (October 1), remember that finding "Kanyas" (young girls for the ritual) in urban areas is getting harder. Many people now coordinate with local orphanages or schools.
- The "No Fire" Rule: If you're observing Sheetala Ashtami on March 22, remember the "no cooking" rule applies to the whole house. Prepare your meals on the 21st.
- Fasting Variations: Not all Ashtami fasts are the same. Some allow fruits (Phalahar), while others are more rigid. Decide your capacity before you commit.
Knowing when is Ashtami 2025 is the first step in aligning your year with these ancient rhythms. Whether it's the roar of the dhak drums in October or the quiet devotion of a monthly Masik Durgashtami, these dates provide a structure to the year that goes beyond the standard work week.
Mark your calendars for October 1st and August 16th specifically. Those are the two you really don't want to miss if you're looking for the full cultural experience. For the rest, a simple digital panchang app can help you track the specific sunrise timings for your city, as the exact start of the Tithi can vary by a few minutes depending on your longitude and latitude.
To ensure your rituals align with local tradition, verify the specific Udaya Tithi with your local temple priest about a week before the dates mentioned, as regional variations in the lunisolar calendar can occasionally shift observance by a single day.
