Chaturdashi tithi is one of the most recognised lunar days in the Hindu calendar, occurring twice every lunar month and carrying special religious significance, particularly for devotees of Lord Shiva. Understanding what chaturdashi tithi means, when it falls, and why it matters can help readers plan fasts, pujas, and other religious observances with greater confidence.
What Is Chaturdashi Tithi?
In the Hindu lunar calendar, each month is divided into 30 tithis (lunar days), split across two phases: Shukla Paksha (the waxing phase of the moon) and Krishna Paksha (the waning phase). Chaturdashi is the 14th tithi in each of these two fortnights, meaning it occurs twice a month:
- Shukla Paksha Chaturdashi — the 14th day of the waxing moon, falling just before Purnima (full moon)
- Krishna Paksha Chaturdashi — the 14th day of the waning moon, falling just before Amavasya (new moon)
Because a tithi is measured by the angular distance between the sun and moon rather than a fixed 24-hour period, chaturdashi tithi does not always align neatly with a single calendar date. It can begin partway through one day and end partway through the next, which is why panchang sources typically list a precise start and end time for chaturdashi tithi rather than a simple date.
The Religious Significance Of Chaturdashi Tithi
Chaturdashi tithi holds particular importance in Hindu religious practice, most notably through Masik Shivratri, a monthly observance dedicated to Lord Shiva that falls on Krishna Paksha Chaturdashi every month. Devotees observe a fast, visit Shiva temples, and perform special pujas during the night hours of this tithi, believing it to be an especially auspicious time for seeking Lord Shiva’s blessings.
Beyond the monthly Masik Shivratri, certain chaturdashi tithis carry even greater significance:
- Narak Chaturdashi (Choti Diwali) — falling on Krishna Paksha Chaturdashi of the Kartik month, this day commemorates Lord Krishna’s victory over the demon Narakasura and is celebrated as part of the broader Diwali festival period
- Maha Shivratri — the most significant of all chaturdashi observances, falling on Krishna Paksha Chaturdashi of the Phalgun or Magh month depending on the regional calendar, and considered one of the most important festivals dedicated to Lord Shiva
- Ananta Chaturdashi — falling on Shukla Paksha Chaturdashi of the Bhadrapada month, marking the culmination of Ganesh Chaturthi celebrations with the immersion of Ganesh idols
How To Check Chaturdashi Tithi Dates
Because tithi timings shift from month to month and can vary slightly by location due to differences in sunrise time, readers looking for the exact chaturdashi tithi date for a specific month should consult a current panchang rather than relying on a fixed calendar date. Most panchang resources display:
- The exact start and end time of chaturdashi tithi for a given date
- Whether the tithi falls in Shukla Paksha or Krishna Paksha
- The associated Hindu month (such as Chaitra, Vaishakh, or Kartik)
- Any festivals or vrats associated with that specific chaturdashi
Since Masik Shivratri occurs on Krishna Paksha Chaturdashi every month, readers following this observance regularly should check the panchang each month rather than assuming a fixed date, since the exact day can shift depending on the lunar cycle.
Chaturdashi Tithi Through 2026
Across 2026, chaturdashi tithi will occur roughly 24 times, twice in each Hindu lunar month, following the natural rhythm of the waxing and waning moon. Some of these occurrences will align with well-known observances such as Masik Shivratri, while the specific Krishna Paksha Chaturdashi falling in the Phalgun or Magh month will mark Maha Shivratri, one of the year’s most widely observed festivals.
For readers planning ahead, it’s worth noting that chaturdashi tithi timings are calculated based on sunrise (Udaya Tithi) in most traditional panchang systems, meaning the tithi considered “active” for a given day is the one prevailing at sunrise, even if it changes to the next tithi later that same day.
Observing A Chaturdashi Vrat
Devotees observing a fast on chaturdashi tithi, particularly for Masik Shivratri, typically follow certain common practices:
- Waking before sunrise and taking a ritual bath
- Offering water, milk, bael leaves, and other items to a Shiva lingam
- Fasting through the day, with many devotees breaking their fast only the following morning
- Chanting the Shiva mantra or reciting the Shiva Chalisa during the night hours, which are considered especially auspicious on this tithi
