Why Satyanarayan Puja Is Tied to Purnima
Shri Satyanarayan Puja, dedicated to Lord Vishnu in his Satyanarayan form, doesn’t have one single fixed date — it’s traditionally performed on Purnima (the full moon day), which occurs roughly once a month. Some households also perform it on other significant occasions such as a housewarming, a new business launch, a wedding, or after a wish has been fulfilled, but Purnima remains the most common and widely recommended occasion for the puja.
2026 Purnima Dates (Monthly List)
Based on Delhi/IST Panchang calculations, the Purnima dates for 2026 fall roughly as follows: Pausha Purnima on January 3, Magha Purnima on February 1, Hutasani/Phalguna Purnima around March 3, Chaitra Purnima on April 1, followed by dates continuing through the year in May, June (note: 2026 includes an Adhik Maas, or leap lunar month, in the May-June period), July, August, September, October, November, and finally Margashirsha Purnima on December 23.
2026 is notable for containing an Adhik Maas (an extra lunar month added periodically to keep the lunar calendar aligned with the solar year), which means the year has 13 Purnimas instead of the usual 12. Sources place the additional Purnima around late May, specifically noted as Adhika Jyeshtha Purnima on May 30, with the regular Jyeshtha Purnima following on June 29. Performing Satyanarayan Puja during this extra Adhik Maas period is traditionally considered to bring additional merit.
Timing Matters as Much as the Date
Because Purnima is a Tithi (lunar day) rather than a fixed calendar day, its exact start and end times shift throughout a 24-hour period and can span across two calendar dates. Panchang sources generally recommend performing the puja in the evening, since the Purnima Tithi sometimes concludes during the morning hours, which would make an evening puja fall outside the correct Tithi window. Some listings note the puja day as the Chaturdashi (the day before Purnima) specifically for evening observance, so it’s worth double-checking whether a source is listing morning-appropriate or evening-appropriate dates before finalizing plans.
Regional and Time Zone Differences
Purnima timings are calculated based on a specific reference location (commonly Delhi or New Delhi in most published Panchangs), and the exact Tithi start and end times shift for other cities and, more significantly, for locations outside India. For devotees outside India — in the US, UK, or elsewhere — the Purnima Tithi may begin on the evening before the India-listed date due to time zone differences, which is worth checking carefully rather than assuming the same calendar date applies everywhere.
How to Confirm the Exact Date for Your Location
Given the timing sensitivity involved — checking not just the date but the specific start and end time of the Purnima Tithi for a specific city — the most reliable approach is to consult a location-specific Panchang (many are available online, allowing users to input their city) or a family priest closer to the date in question, rather than relying on a general national list. This is especially important for anyone planning to combine the puja with another major life event, like a housewarming or wedding, where getting the exact timing right carries added significance.
