You are probably trying to settle one of three questions: whether March 15 is your Ekadashi observance, when Dwadashi begins, or which parts of Sunday are suitable for worship and new work. The date has a clear tithi transition, but the decision you act on still depends on your city’s sunrise and the rules of your sampradaya.
For many Indian locations, Krishna Paksha Ekadashi continues until 6:58 AM on Sunday, March 15, 2026. Krishna Paksha Dwadashi begins after that. The common mistake is treating 6:58 AM as a complete instruction. A tithi boundary, the vrata date, the parana window, and the day’s caution periods answer four different questions.
Key takeaways for March 15, 2026
- Weekday: March 15, 2026 is Sunday, or Ravi-vara, traditionally associated with Surya.
- Tithi: Krishna Paksha Ekadashi lasts until 6:58 AM for many Indian locations; Krishna Paksha Dwadashi follows.
- Vrata decision: Many communities determine the Ekadashi observance by the tithi prevailing at local sunrise, not simply by the civil date or the number of hours Ekadashi occupies.
- Parana: Do not assume that the fast should be broken at 6:58 AM. Use the parana window attached to your location, observed vrata, and sampradaya.
- Abhijit Muhurta: The generally favorable interval is centered on true local solar noon, approximately 24 minutes before and after it. It is not automatically 12:00 PM.
- Sunday caution periods: Yamaganda occupies the fifth eighth of local daylight, Gulika the seventh, and Rahu Kalam the eighth.
If you only need a sound plan for personal worship, begin with local sunrise, observe the vrata according to your tradition, and reserve exact muhurta calculations for undertakings that truly require them. If you are arranging parana or a formal ceremony, the city and sampradaya cannot be left unspecified.
Why the 6:58 AM tithi change does not decide the vrata by itself
A civil date begins at midnight. A tithi does not. It is determined by the changing angular relationship of the Moon and Sun, with each tithi corresponding to another 12 degrees of separation. Because their apparent motion is not uniform, a tithi may begin or end at any hour. That is why March 15 can contain the end of Ekadashi and most of Dwadashi without becoming a simple choice between two all-day labels.
Sunrise supplies the practical dividing line used by many Hindu observance rules. If your local sunrise occurs before the 6:58 AM transition, Ekadashi is present at sunrise. If sunrise occurs after the transition, Dwadashi is already present. This is the first check to make before copying a calendar label from another city.
That check is necessary, but it may not be sufficient. Smarta and Vaishnava practice can apply different rules to an Ekadashi touching sunrise, and a valid parana can depend on Hari-vasara and on whether Dwadashi remains at the relevant following sunrise. A household following a particular matha, temple, or acharya should use that lineage’s calendar rather than combining the vrata date from one system with the parana time from another.
Most importantly, 6:58 AM marks the transition into Dwadashi; it is not, by itself, permission to end an Ekadashi fast. Complete the vrata prescribed for the observance day and take the parana interval from a location-specific Panchang. This prevents both an early break and the accidental loss of the permitted Dwadashi window.
If a strict food or water fast could be unsafe for you, ask a qualified clinician and your acharya about a suitable form of observance. Japa, restraint, satvika food, dana, and careful speech preserve the vrata’s ethical direction without treating physical hardship as the measure of devotion.
A practical worship plan for this Sunday
Sunday adds a solar emphasis to the waning-fortnight discipline of Ekadashi. In classical jyotisha, Ravi-vara is associated with Surya, clarity, vitality, and steadiness. You can honor both currents without turning the day into a complicated sequence of rituals.
- Set the correct location before the day begins. Record local sunrise and sunset, the local tithi-end time, and the parana window issued for your tradition. If you live outside India, verify the time zone and daylight-saving setting rather than converting an Indian clock time informally.
- Begin at local sunrise. Where feasible, offer arghya to Surya, recite a familiar Surya prayer such as Aditya Hridayam, or sit for quiet contemplation facing the morning light. Keep the practice appropriate to your household tradition.
- Make a clear sankalpa. If March 15 is the Ekadashi vrata day under your calendar, decide the form of upavasa you will keep and the spiritual discipline accompanying it. Japa, dhyana, scriptural study, mindful speech, and reduced distraction give the fast a purpose beyond food restriction.
- Do not abandon the sankalpa merely because Dwadashi begins at 6:58 AM. The tithi has changed, but the vrata and parana rules still belong to the observance as a whole. Follow the parana instruction supplied for that vrata.
- Use the rest of the day for sattvika action. Dana, seva, gratitude, and a simple diet where permitted are more aligned with Ekadashi discipline than filling the day with calculations while neglecting conduct.
The dharmic resonances of restraint should not be used to erase distinctions between traditions. Buddhists may deepen meditation in an Uposatha-inspired spirit; Jains may emphasize Samayik, Paushadha, and vigilance toward ahimsa; Sikhs may give greater attention to simran and seva. These are meaningful parallels, not a claim that the Hindu Panchang automatically creates the same formal observance in every dharmic calendar.
Calculate Sunday’s Rahu Kalam and other planning windows
Fixed clock-time charts are convenient, but they become inaccurate when moved between cities or seasons. Rahu Kalam, Yamaganda, and Gulika are calculated from the actual interval between local sunrise and sunset. The method is simple enough to check yourself.
- Write down local sunrise and sunset for March 15.
- Subtract sunrise from sunset to obtain the daylight duration.
- Divide the daylight duration by eight. Call the result one segment.
- Count the weekday-specific segments forward from sunrise.
| Planning marker | Sunday calculation | How to apply it |
|---|---|---|
| Yamaganda | Fifth daylight segment: sunrise plus 4 segments through sunrise plus 5 segments | Avoid beginning a discretionary undertaking during this interval when following traditional muhurta practice. |
| Gulika | Seventh daylight segment: sunrise plus 6 segments through sunrise plus 7 segments | Treat it as another caution period for initiations, using the convention followed by your regional Panchang. |
| Rahu Kalam | Eighth daylight segment: sunrise plus 7 segments through sunset | Sunday places Rahu Kalam at the end of daylight. Avoid starting important new work then; an activity already underway need not automatically be abandoned. |
| Abhijit Muhurta | Approximately 24 minutes before through 24 minutes after true local solar noon | Use it as a generally favorable window for work requiring clarity or decisiveness, not as a substitute for a ceremony-specific muhurta. |
The Sunday sequence is the fifth segment for Yamaganda, seventh for Gulika, and eighth for Rahu Kalam. Suppose your Panchang gives sunrise as S-rise, sunset as S-set, and one-eighth of daylight as E. Yamaganda then runs from S-rise plus 4E to S-rise plus 5E; Gulika from S-rise plus 6E to S-rise plus 7E; and Rahu Kalam from S-rise plus 7E to S-set. Use the exact sunrise and sunset values rather than rounding them before division.
Abhijit Muhurta follows a different reference point. It is centered on true local solar noon and spans roughly 24 minutes on either side. Clock noon and solar noon are not necessarily the same, so 11:36 AM to 12:24 PM should not be copied as a universal interval. A reliable local Panchang can give the correct center.
Choghadiya is separate again. Day and night are each divided into eight segments, then assigned a rotating quality. Amrit, Shubh, and Labh are commonly treated as favorable; Udveg, Rog, and Kaal as challenging. Do not divide the full 24-hour day into eight or assume that the Rahu Kalam segment tells you the Choghadiya quality. Use the day and night rotations supplied for Sunday in your local calendar.
These caution periods chiefly govern the initiation of optional undertakings. They do not mean that worship, caregiving, necessary travel, medical attention, or ordinary responsibilities must stop when a segment begins. Muhurta is meant to order action with discernment, not to turn duty into paralysis.
What to verify before a sankalpa or major ceremony
The Ekadashi-Dwadashi transition is enough to structure a simple devotional day. It is not enough to schedule a wedding, major samskara, consecration, or another specialized rite. A full Panchang check considers Vara, Tithi, Nakshatra, Yoga, and Karana; the Moon’s Rashi is also commonly displayed because it adds another layer to the election of a time.
- Nakshatra: Confirm which lunar mansion prevails at the proposed hour and whether it changes during your planned window. A civil day’s opening Nakshatra cannot safely be assumed to last until night.
- Moon Rashi: Check the Moon sign at the actual time of the undertaking. The Moon moves quickly enough that a daily label may conceal an intraday transition.
- Yoga: Verify the Yoga calculated from the combined solar and lunar longitudes. It can refine whether a time supports the character of the intended work.
- Karana: Because a Karana is half a tithi, it changes more frequently than the tithi headline. It is often considered for travel, negotiation, and ritual action.
- Location settings: Confirm city, time zone, and any daylight-saving rule. This affects sunrise, sunset, local solar noon, and every interval derived from them.
- Sampradaya rules: Use one internally consistent calendar for the vrata date, Hari-vasara restriction, and parana. Do not assemble those three decisions from unrelated traditions.
Abhijit Muhurta can be helpful for an ordinary initiative when a favorable general window is wanted. It should not be used alone to authorize a marriage or another rite with specialized conditions. In that situation, take the proposed city, participants’ details where your tradition requires them, and the full Panchang to a competent priest or jyotishi.
Before March 15 arrives, put four items in your calendar: local sunrise, the local Ekadashi end, the correct parana window, and Sunday’s calculated caution periods. Once those are fixed, keep the day simple: worship at sunrise, honor the vrata without improvising its ending, and postpone any major ceremony until all relevant Panchang limbs have been checked.
