If you are arranging a vrata, puja, sankalpa, or family observance on October 26, the important boundary is not midnight. On Monday morning, Purnima is still in effect, but the tithi changes at 9:57 AM.
The practical answer is simple: use Purnima until 9:57 AM on October 26 and Krishna Paksha Pratipada after 9:57 AM. Pratipada then continues until 8:27 AM on October 27. If your observance has rules tied to sunrise, moonrise, or a locally calculated muhurta, confirm those separately rather than treating the tithi boundary as a complete muhurta.
October 26 tithi schedule at a glance
| Date and time | Tithi | What it means for planning |
|---|---|---|
| October 26, before 9:57 AM | Purnima | The full-moon tithi is still present. |
| October 26, from 9:57 AM onward | Krishna Paksha Pratipada | The first tithi of the waning fortnight has begun. |
| October 27, until 8:27 AM | Krishna Paksha Pratipada | The same tithi continues into the following civil day. |
No later tithi is identified here for October 27. If you need to plan anything after 8:27 AM that day, consult the Panchang entry for October 27 instead of assuming which tithi follows or when another factor becomes favourable.
Why one Monday contains two tithis
A tithi is a lunar day, not a label permanently attached to a civil date. Its beginning and end are determined by the changing angular relationship between the Sun and Moon, so a tithi can end in the morning, afternoon, or night. Midnight does not reset it.
That distinction matters on October 26. The date begins under Purnima, the full-moon tithi. At 9:57 AM, the calendar moves into Krishna Paksha Pratipada, the first lunar day of the waning or dark fortnight. This is therefore both a tithi change and a paksha transition.
If you make a sankalpa before the change, Purnima is the applicable tithi. If you make it after the change, Krishna Paksha Pratipada is applicable. Write the cutoff into your plan, especially when several family members or temple volunteers are coordinating the observance.
How to use the 9:57 AM transition correctly
- Identify the rule governing your observance. A practice prescribed for Purnima is not automatically interchangeable with one prescribed for Krishna Paksha Pratipada.
- Compare the actual ritual time with 9:57 AM. A morning act completed before that boundary falls under Purnima; one performed after it falls under Pratipada.
- Check whether your sampradaya uses another deciding condition. Some observances depend on the tithi at sunrise, while others also involve moonrise, a particular part of the day, or the conjunction of additional Panchang limbs.
- Use your local Panchang when location matters. Panchang clock times are location-sensitive, so a time printed for one region should not be carried unchanged to another time zone.
- For a strict vrata or temple programme, follow the calendar accepted by your temple, guru, or family parampara. This prevents a technically correct calculation from conflicting with the convention governing the observance.
If your purpose is ordinary daily worship rather than a rule-bound vrata, you do not need to turn the transition into a source of anxiety. Note the tithi current at the time of worship and proceed according to your practice.
What this tithi timing does not establish
A tithi is only one limb of a full Panchang. The October 26 timing above does not by itself tell you the day’s nakshatra, yoga, karana, sunrise, sunset, moonrise, Rahu Kalam, or a complete auspicious muhurta. It should not be used alone to select a wedding, griha pravesh, major purchase, journey, or another undertaking that requires a fuller electional calculation.
Monday is the weekday, but the weekday also does not override the tithi boundary. Avoid attaching a deity, festival, fast-breaking time, or promised result merely because the date is a Monday or begins with Purnima. Those conclusions require the rules of the particular observance and, in many cases, more Panchang information.
The safest way to plan is to separate two questions. First ask, “Which tithi is active when I will perform the act?” Then ask, “Does this observance require any condition besides tithi?” The first question is answered by the 9:57 AM cutoff. The second must be answered from your tradition’s procedure and a complete local Panchang.
Key takeaways
- October 26, 2026 falls on a Monday.
- Purnima remains until 9:57 AM on October 26.
- Krishna Paksha Pratipada begins after 9:57 AM and lasts until 8:27 AM on October 27.
- Use the tithi active at the actual time of your sankalpa or ritual.
- Verify local timing and any sunrise, moonrise, or muhurta requirements before a rule-bound observance.
Mark 9:57 AM beside your October 26 plan now. Then check the rule for your specific vrata or ceremony with the local Panchang your family or temple follows; that one step will keep a clear tithi answer from being mistaken for a complete ritual determination.
