If you are deciding whether a puja, vrata, or sankalpa on October 8 belongs to Trayodashi or Chaturdashi, the important point is the evening transition. On Thursday, October 8, 2026, Krishna Paksha Trayodashi continues until 9:52 PM, after which Krishna Paksha Chaturdashi begins.
That means the civil date carries two tithis. You should compare the intended time of your observance with the transition rather than treating the printed date as one uninterrupted lunar day. Because panchang timings are location-sensitive, confirm the change in a calendar calculated for your location before fixing a formal ritual.
October 8, 2026 panchang at a glance
| Calendar element | Details |
|---|---|
| Civil date | Thursday, October 8, 2026 |
| Paksha | Krishna Paksha, the waning or dark half of the lunar month |
| Tithi until 9:52 PM | Trayodashi, the thirteenth lunar day |
| Tithi from 9:52 PM onward | Chaturdashi, the fourteenth lunar day |
This timeline answers the immediate tithi question. It does not, by itself, establish a complete muhurta. If you are choosing a time for a ceremony or another consequential samskara, you still need the relevant local panchang factors and the rules followed by your family, temple, or sampradaya.
Why one Thursday contains two tithis
A civil date runs from midnight to midnight. A tithi follows the relationship between the Sun and Moon, so its boundary does not have to coincide with midnight. It can change in the morning, afternoon, evening, or night.
On October 8, the relevant boundary falls at 9:52 PM. An action performed earlier falls within Trayodashi under this timing; an action performed after the transition falls within Chaturdashi. This distinction matters whenever the ritual instruction specifies that a particular tithi must prevail at the time of worship.
Do not automatically move an observance merely because Chaturdashi appears beside October 8 in a calendar. Likewise, do not assume the entire Thursday is Trayodashi because that is the tithi prevailing through most of the date. The deciding rule may depend on the tithi at sunrise, during a prescribed worship period, or at another ritual moment.
How to use the transition when planning an observance
- Identify what your practice actually requires. Routine daily worship usually does not need to be rearranged around every tithi change. A tithi-specific vrata, puja, or sankalpa may have a precise rule.
- Check the intended time. If the required act will occur before 9:52 PM, the working tithi is Trayodashi. If it will occur after 9:52 PM, the working tithi is Chaturdashi.
- Ask whether the rule uses sunrise or a special ritual period. The tithi present at the moment of an observance is not always the sole criterion. Follow the method prescribed by your tradition rather than choosing whichever label seems more convenient.
- Verify the location. Use a panchang set for the place where the observance will actually happen. A transition printed for another region should not be copied mechanically into your local schedule.
- Keep tithi and muhurta separate. Tithi is one part of the decision. Do not declare the whole day suitable or unsuitable for an important undertaking from this one entry alone.
If two calendars differ slightly, first check whether they use the same location and time zone. Do not average their transition times. For a formal observance, use the calendar followed by the officiating temple or priest so that the sankalpa and performance follow one consistent system.
Key takeaways for October 8
- October 8, 2026 is a Thursday in the civil calendar.
- Krishna Paksha Trayodashi prevails until 9:52 PM in the cited calendar.
- Krishna Paksha Chaturdashi begins after the 9:52 PM transition.
- A tithi-specific observance must be matched to its prescribed ritual time, not merely to the date printed on a calendar.
- For a formal puja, vrata, or muhurta, confirm the transition with a panchang calculated for your location.
For practical planning, mark October 8 as Trayodashi until 9:52 PM and Chaturdashi thereafter. Before making a formal sankalpa, verify the local timing and the rule your tradition applies. The useful question is not simply, “What is the tithi on October 8?” It is, “Which tithi prevails when this observance must be performed?”
