This guide walks through the Tamil Calendar for July 2026 in plain, everyday language. Every date below has been checked against multiple Panchangam sources rather than repeated from a single listing, which turned up several corrections worth knowing before you plan your month around it — more on those below. As always, exact Tithi and Nakshatra timings can shift by a few hours depending on your city, so confirm precise muhurtham windows with your family priest or a local Panchangam before finalising any major event.
Tamil Calendar Festivals and Muhurtham Dates: July 2026
Below is a simplified table of the key Panchangam dates, fasting days, and observances that fall in July 2026, cross-checked against multiple sources for accuracy.
| Date (2026) | Day | Tamil Masam | Occasion |

| July 12 | Sunday | Aani | Pradosham |
| July 14 | Tuesday | Aani | Amavasai (New Moon – Tarpanam Day) |
| July 17 | Friday | Aadi (begins) | Aadi Pirappu / Dakshinayana Punyakalam |
| July 19 | Sunday | Aadi | Skanda Sashti Vratham |
| July 25 | Saturday | Aadi | Devshayani Ekadashi (Shukla Paksha); Chaturmas begins |
| July 26 | Sunday | Aadi | Pradosham (second of the month — a rare double Sunday Pradosham) |

A quick but important correction: several calendars circulating online list Aadi Pooram as falling in July. Based on standard Panchangam calculations, that isn’t correct this year — Aadi Pooram, the festival dedicated to Andal, actually falls on August 14, 2026, along with Aadi Perukku (August 3) and Aadi Karthigai (August 6–7). July only captures the very start of Aadi Masam; its signature festivals arrive the following month.
How to Download and Use This Tamil Calendar for July 2026
If you’d like to keep this calendar handy through the month — printed out, saved as a phone wallpaper, or pinned near the family altar — you can save this page directly from your browser using the “Print” or “Save as PDF” option, which keeps the festival table above intact for quick reference. If your family follows a specific temple-published or regional Panchangam, it’s worth cross-checking that source too, since a few Nakshatra and Tithi timings can vary by an hour or so depending on the calculation method and your exact location.
Major Observances in the July 2026 Tamil Calendar
Yogini Ekadashi — July 10, 2026
The first Ekadashi of the month falls in Aani’s waning fortnight and is dedicated to Lord Vishnu. Tradition holds that observing this fast with devotion clears past transgressions and brings peace of mind — it’s widely observed just before the more significant Devshayani Ekadashi later in the month.
Pradosham — July 12 and July 26, 2026
This year brings a genuinely unusual coincidence: both Pradosham days in July fall on a Sunday, making each one a Ravi Pradosham — considered especially beneficial for health, longevity, and Surya worship alongside the usual Shiva puja. Having two Sunday Pradoshams in the same month is uncommon enough that it’s worth marking on your calendar if your family observes this fast regularly.
Amavasai — July 14, 2026
This new moon day falls in the final stretch of Aani Masam and is traditionally reserved for Tarpanam — offerings to ancestors. Since it also falls on a Tuesday this year, it carries the added significance of a Bhauma (Mangal) Amavasai, considered favourable for Hanuman worship and for resolving longstanding disputes or obstacles.
Aadi Pirappu — July 17, 2026
The first day of Aadi Masam is marked by Dakshinayana Punyakalam, the beginning of the Sun’s southward journey. Many families perform Tarpanam on this day, and it’s traditionally treated as the start of six months considered less favourable for major life events, even as temple activity — particularly Amman worship — picks up considerably through the month. Fridays falling within Aadi (Aadi Velli) and Tuesdays (Aadi Chevvai) are both considered especially auspicious for temple visits throughout the month, even though the month as a whole avoids weddings and housewarmings.
Skanda Sashti Vratham — July 19, 2026
Just two days into Aadi Masam, this monthly fasting day dedicated to Lord Murugan falls on the Shukla Paksha Sashti tithi. Devotees fast from sunrise and break the fast the following morning after prayers, with many visiting Murugan temples such as Palani, Thiruchendur, or Thiruparankundram.
Devshayani Ekadashi and the Start of Chaturmas — July 25, 2026
This is one of the most significant Ekadashis of the year across the Tamil Panchangam and the wider Hindu calendar. Also known as Ashadhi or Hari Shayani Ekadashi, it marks the day Lord Vishnu is believed to enter his four-month yogic sleep (Chaturmas), a period during which many auspicious ceremonies are traditionally paused — reinforcing Aadi’s broader reputation as a month for spiritual withdrawal rather than celebration. Chaturmas runs roughly from this Ekadashi through late October or early November, meaning its overlap with Aadi Masam is one of the reasons the month carries such a consistent “avoid new beginnings” reputation across Tamil households, independent of the Aadi-specific solar-calendar customs.
Pournami / Guru Purnima — July 29, 2026
The month’s full moon coincides with Guru Purnima (also called Vyasa Purnima), the day set aside across Hindu, Buddhist, and Jain traditions to honour teachers and spiritual guides. In Tamil households, this Pournami is also treated as a significant day for Satyanarayana Puja and river or tank bathing where possible.
How Aadi Masam Compares Across South Indian Calendars
If you’ve noticed friends from other South Indian states referring to a different month name during the same weeks, that’s expected. Aadi Masam corresponds to Ashadha and part of Shravana in the North Indian Purnimanta reckoning, and to Ashadha–Shravana Masam in the Amanta systems followed in Andhra Pradesh, Telangana, Karnataka, and Maharashtra. It coincides with Karkidakam in the Malayalam calendar — where it carries an almost identical reputation for being spiritually intense but socially quiet — and with Shraban in the Bengali Panjika. The underlying Tithi-based festivals (Ekadashi, Amavasai, Pournami, Pradosham) fall on the same days regardless of which regional month name is used, since those are lunar observances; it’s only the solar month name and its cultural associations that shift from one calendar tradition to another.
Muhurtham Guidance for July 2026
Aadi Masam has a well-earned reputation as the least preferred month of the Tamil year for weddings, Griha Pravesham, and business launches, and July 2026 is no exception once Aadi begins on the 17th. A few points worth keeping in mind:
- The first half of the month (July 1–16, still in Aani Masam) can carry ordinary muhurtham dates — check specific Tithi and Nakshatra combinations with your family astrologer
- Once Aadi begins on July 17, most families reserve the month for Amman pooja, temple visits, and religious observance rather than weddings or housewarming ceremonies
- Aadi Velli (Fridays in Aadi) and Aadi Chevvai (Tuesdays in Aadi) are considered especially good for temple worship, even within an otherwise “inauspicious” month
- Ekadashi (July 10, July 25) and Amavasai (July 14) are fasting and remembrance days, not typically used for celebrations regardless of which Tamil month they fall in
Why the Tamil Calendar Still Matters in Aadi Masam
Aadi is arguably the month where the Tamil calendar matters most to ordinary households, precisely because so many families organise their year around avoiding it for weddings while embracing it for Amman worship, Koozh offerings at temples, and the reflective mood that Dakshinayana is said to bring. Knowing exactly when Aani ends and Aadi begins — and which of the month’s fasting days fall where — makes it far easier to plan July with intention, whether that means scheduling a last Aani-month function before the 17th or simply marking your calendar for Skanda Sashti and the two Ravi Pradoshams.
Frequently Asked Questions
When does Aadi Masam begin in 2026? Aadi Masam begins on Friday, July 17, 2026, and continues until August 16.
Does Aadi Pooram fall in July 2026? No. Aadi Pooram, dedicated to Andal, falls on August 14, 2026 — well into the second half of Aadi Masam, not at its start.
How many Ekadashi days fall in July 2026? Two: Yogini Ekadashi on July 10 and Devshayani Ekadashi on July 25, which also marks the beginning of Chaturmas.
Why are there two Pradosham days on a Sunday in July 2026? Both Trayodashi tithis this month happen to fall on a Sunday, making both Pradoshams Ravi Pradosham — a relatively uncommon coincidence worth noting if your family observes this fast.
Is July 2026 a good month for weddings on the Tamil calendar? The first half (through July 16, still Aani Masam) can carry ordinary muhurtham dates depending on individual horoscopes. Once Aadi begins on July 17, most Tamil families avoid scheduling weddings or housewarming ceremonies until the month ends in mid-August.
