Partial Lunar Eclipse 28 August 2026: What to Know
A partial lunar eclipse falls on 28 August 2026, the same day as Raksha Bandhan and Shravana Purnima. The Moon sets across India before the eclipse begins, so it is not visible here, there is no sutak, and rakhi timing is untouched.
A partial lunar eclipse (Chandra Grahan) occurs on 28 August 2026 — the same day as Raksha Bandhan and Shravana Purnima. Because a lunar eclipse can only occur on a full moon (Purnima) tithi, its arrival on Shravana Purnima is not an accident of the calendar. But the detail that settles almost every question families are asking this year is a simple one: the eclipse is not visible anywhere in India. The Moon has already set across the country before Earth's shadow touches it.
When the eclipse happens, and where it can be seen
The contact times, in IST:
- Penumbral phase begins — 06:54
- Umbral (khandagras) phase begins — 08:04
- Greatest eclipse — 09:43
- Umbral phase ends — 11:22
- Penumbral phase ends — 12:32
The eclipse begins while the Purnima tithi is still running, and its faint penumbral closing phase continues for a while after the tithi has ended. Every one of those moments falls after moonset in India. The Moon sets at 05:51 in Delhi, 06:17 in Mumbai, 05:10 in Kolkata and 05:30 in Varanasi. By the time the umbral phase begins the Moon is far below the horizon — 24.2 degrees below it at Delhi, 22.2 at Mumbai, 30.0 at Varanasi and 35.5 at Kolkata — and it stays below the horizon through every stage of the eclipse, everywhere in the country. The eclipse is visible from the Americas, the Atlantic and parts of western Europe.
What kind of eclipse is this, and why it lands on Purnima
Every lunar eclipse takes place at Purnima, when the Sun, Earth and Moon fall close to a straight line and the Moon passes through Earth's shadow. A partial eclipse (khandagrahan) means the Moon dips through only part of Earth's darker umbral shadow rather than being swallowed by it entirely — visually, and in classical reckoning, milder than a total (purna) eclipse. Vedic astrology treats Chandra Grahan as a lunar event above all else: the Moon governs manas, the mind, along with emotional steadiness, sleep, bodily fluids, and the mother figure in one's life. A grahan touching the Moon is read as a temporary disturbance to precisely these areas — more so for anyone whose natal Moon is weak, afflicted by Rahu or Ketu, or placed in a dusthana house (the 6th, 8th or 12th) of their birth chart.
What the Raksha Bandhan overlap actually means
Far less than the shared date suggests. Sutak applies only where an eclipse is actually visible — this is the mainstream classical position, as the major panchangs state — and this eclipse is visible nowhere in India. There is therefore no sutak kaal in India on 28 August, and the eclipse imposes nothing at all on Raksha Bandhan. Temples keep their usual hours, stored food does not need to be covered, and cooking is not restricted.
The only timing consideration for rakhi this year is Bhadra, and Bhadra falls entirely on 27 August, running from 09:09 to 21:33 IST. It has lifted well before the morning of the 28th. Rakhi may be tied on 28 August from sunrise until the Purnima tithi ends at 09:49 IST. That closing instant is the same everywhere in India; only sunrise differs, so the window is 3 hours 25 minutes in Mumbai (06:24 to 09:49) and 4 hours 30 minutes in Kolkata (05:19 to 09:49). Families who follow the rule that rakhi may be tied once Bhadra has lifted also have the night of 27 August, from 21:33 onward. Sunrise for your own city and the full muhurat detail are on the panchang.
Sutak kaal: what it means when an eclipse is visible
None of what follows applies in India on 28 August 2026. With the Moon below the horizon throughout, no sutak is observed here at all. It is included because sutak is a real part of eclipse practice, and worth knowing for the eclipses that are visible where you live.
For a lunar eclipse, sutak traditionally begins nine hours before the eclipse starts, in the places where the eclipse can actually be seen. Where that applies, classical practice within the window recommends:
- Avoiding cooking or eating, particularly for pregnant women and the elderly — many households place tulsi leaves in stored food and water as a traditional buffer
- Postponing new ventures, griha pravesh, and other auspicious sankalpas until after the eclipse ends
- Keeping temple sanctums closed, with the murti covered until the eclipse passes and the space is ritually purified again
- Favouring quiet, low-exertion activity — this is treated as a window for japa and reflection rather than routine work
Children, the sick, and the very elderly are traditionally exempted from strict sutak fasting. A partial eclipse is treated by most traditional authorities as comparatively mild in intensity next to a total one. And the principle underlying the whole practice is tied to visibility: an eclipse that never rises above your horizon does not bring sutak with it.
Remedies once the eclipse ends
Where an eclipse is seen, the standard sequence once the Moon is released from shadow is bathing (a few drops of Ganga jal added to your water is customary), changing into fresh clothes, and donating white items associated with the Moon — rice, milk, white cloth, sugar, or silver — to those in need. In India there is nothing to wait out this time, and anyone who wishes to keep these observances can take them up at any time on the 28th. Chanting the Chandra mantra, "Om Som Somaya Namah," or the Maha Mrityunjaya mantra is widely recommended, along with offering water to the Moon when it rises that evening. If your chart carries a Chandra dosha, or a Rahu-Ketu axis sitting close to your natal Moon, this period is traditionally regarded as a favourable time to take up such remedial worship in earnest rather than deferring it further.
Who should pay closer attention
Eclipse effects in Vedic astrology are read primarily through the rashi the eclipse occurs in, together with the houses it activates from your natal Moon and Lagna. Those whose Moon sign falls in or near the affected rashi, or whose current mahadasha or antardasha is running Moon, Rahu, or Ketu, tend to feel this period more distinctly — as restlessness, disturbed sleep, or heightened emotional intensity around the eclipse date. Rather than guessing, it is worth checking exactly how this grahan lands against your own chart. A free detailed Kundli analysis will show your natal Moon's placement and running dasha, which is the fastest way to know whether this eclipse touches you lightly or significantly.
If the 28 August grahan falls in a sensitive house of your chart, or you have been carrying a lingering Chandra dosha, it is worth addressing properly rather than leaving it to chance — book a consultation with our astrologers to understand exactly what this eclipse means for your chart and which remedy fits your specific placements.
