September 21, 2026 Hindu Panchang: Dashami to Ekadashi

If you are arranging Monday’s puja, a tithi-based observance, or a family ritual, September 21 cannot be treated as though it has one tithi from morning to night. The practical point is the evening transition: Dashami governs the earlier part of the day, while Ekadashi begins afterward.

Use the listed changeover to identify the tithi at your chosen time. If the observance depends on local sunrise, a particular sampradaya’s rules, or a complete muhurta, confirm those separately rather than trying to derive them from the tithi alone.

September 21 Panchang at a glance

For most regions, Shukla Dashami continues until 6:19 PM on September 21, after which Shukla Ekadashi begins. The Gregorian date and weekday remain Monday when the tithi changes; only the lunar-day designation moves from the tenth tithi to the eleventh.

How to read a day with two tithis

A tithi does not have to begin at midnight or last for an entire civil date. That is why a calendar can correctly identify September 21 with both Dashami and Ekadashi. The clock time of your activity determines which of those two tithi names applies.

For an activity clearly completed before the listed transition, read the tithi as Shukla Dashami. For an activity beginning after the transition, read it as Shukla Ekadashi. If the precise tithi at the start of a sankalpa matters, avoid scheduling directly on the boundary and verify the transition for your location.

This distinction also prevents a common calendar mistake: seeing “Dashami” beside the date and assuming it remains Dashami throughout Monday. On September 21, that shortcut becomes inaccurate after 6:19 PM.

Plan worship without turning a tithi into a muhurta

The Dashami-to-Ekadashi transition tells you which lunar day is operating. It does not, by itself, declare every earlier or later hour auspicious for every purpose. A complete muhurta decision can depend on additional Panchang elements, the nature of the rite, local calculations, and the tradition being followed.

1. Write down the location where the observance will occur and the local clock time at which it will begin.
2. If it begins before 6:19 PM under the applicable calendar, identify the tithi as Shukla Dashami.
3. If it begins after the transition, identify the tithi as Shukla Ekadashi.
4. If the rite requires a full sankalpa or an auspicious starting time, ask the officiating priest or consult a Panchang calculated for that location. Do not fill in missing calendar elements by assumption.
5. Keep one calendar convention throughout the decision. Mixing a tithi from one location with timings from another can produce an internally inconsistent plan.

For ordinary personal prayer, the transition may simply tell you how to name the lunar day. For a temple service, samskara, vrata, or other rule-bound observance, the tradition’s own decision method should govern.

Do not infer the Ekadashi vrata date from onset alone

The beginning of Ekadashi tithi at 6:19 PM answers one narrow question: when the calendar changes from Dashami to Ekadashi on September 21. It does not, on its own, settle every question about when an Ekadashi vrata should be observed or broken.

If your actual decision concerns fasting, use the Ekadashi calendar followed by your temple, guru-parampara, or household tradition for your location. Ask specifically for the observance date and parana instructions rather than assuming that the evening onset automatically determines both. This keeps the tithi calculation and the religious rule for observing it from being confused with each other.

The same discipline applies when relatives in different cities are coordinating a vrata. Share the local calendar determination, not merely “Ekadashi starts in the evening,” because a clock time should not be transferred between locations without checking the relevant Panchang.

Key takeaways for September 21

• Monday, September 21, 2026 falls in Shukla Paksha.
• Shukla Dashami remains in effect until the listed transition at 6:19 PM.
• Shukla Ekadashi begins after that transition.
• Use the start time of your activity to identify its tithi, but verify the clock time for your location when precision matters.
• Do not treat a tithi transition as a complete muhurta or as a complete Ekadashi-vrata determination.

Before fixing a tithi-dependent observance, record your city, intended start time, and religious tradition. Those three details will tell your priest or local calendar exactly what must be checked, while the September 21 entry supplies the essential starting point: Dashami before the evening change and Ekadashi afterward.
