Sankashti Chaturthi is a monthly fast dedicated to Lord Ganesha, observed on the Chaturthi (fourth tithi) of the Krishna Paksha — the waning half of each lunar month. This free calendar shows the upcoming Sankashti Chaturthi for your location, along with the timing that matters for breaking the fast after moonrise. No birth details are required — just pick your city.
The name comes from "Sankashti," meaning deliverance from difficult times. The vrat is offered to Ganesha as Vighnaharta, the remover of obstacles, and is believed to bring relief from troubles and the fulfilment of wishes. Because it falls once in every lunar month, there are twelve or thirteen Sankashti Chaturthis in a year.
It is distinct from Vinayaka Chaturthi, which is observed in the bright fortnight (Shukla Paksha). The Sankashti Chaturthi that falls in the month of Magha is regarded as the most important of the year.
Devotees keep a fast from sunrise and break it only at night, after Chandra Darshan — sighting the moon — followed by Ganesha puja with offerings such as modak and durva grass. Since moonrise varies from place to place, the exact time to break the fast differs by city, which is why this calendar is tied to your chosen location.
Selecting your city gives you the correct Sankashti Chaturthi date and the local timing so you can plan the vrat, puja, and paran (breaking the fast) accurately.
Both are monthly Ganesha observances tied to the Chaturthi tithi. Sankashti Chaturthi falls in the Krishna Paksha (waning fortnight) and its fast is broken at night after moonrise, while Vinayaka Chaturthi falls in the Shukla Paksha (waxing fortnight) and is centred on midday worship.
When Sankashti Chaturthi falls on a Tuesday (Mangalvar), it is called Angarki Chaturthi. It is considered especially powerful for Ganesha worship, and observing it is believed to carry the merit of many months of the vrat.
No. Sankashti Chaturthi is a calendar observance, not a birth-chart calculation. Just select your city so the fasting date and the moon-sighting time match your location.
