Purnima is the full-moon tithi that closes the bright Shukla Paksha each lunar month, when the Moon stands 180 degrees from the Sun and its disc appears completely full. It is a traditional day of vrat and worship, most often the Satyanarayan Vrat, and the tithi that carries Guru Purnima, Sharad Purnima and Kartik Purnima. This calendar lists the upcoming Purnima dates for your city, each fixed by the tithi running at your local sunrise. No birth details are needed.

In the Vedic lunar calendar a tithi is the time the Moon takes to gain 12 degrees on the Sun, and Purnima is the 15th and final tithi of the waxing Shukla Paksha. At that point the Moon is 180 degrees from the Sun - directly opposite - so we see its face fully lit. The tithi that follows, Pratipada, opens the waning Krishna Paksha.
Purnima is widely kept as a vrat. Devotees fast through the day and perform the Satyanarayan Puja, traditionally breaking the fast after darshan of the risen full Moon. Because the vrat follows the tithi rather than the clock, this calendar resolves each full-moon tithi against your local sunrise so you know the correct day to observe it.
Every lunar month has one Purnima, and many are named for the festival they carry:
The festival attached to a Purnima does not change how its date is found. Every one of them is fixed by the same rule, the tithi running at your local sunrise, so a named Purnima can fall on different civil dates in two cities exactly as an ordinary one can.
Purnima Vrat is an observance kept through the whole day, so the anchor is sunrise. The rule is stated in Kane, History of Dharmasastra Vol. V Part I, p. 73: religious acts prescribed for the gods by day are begun in the morning even if the tithi is mixed with another on that day, so a day-long observance is governed by the tithi prevailing at sunrise. This calendar takes exactly that day, computed against the true sunrise for your latitude, longitude and time zone.
Occasionally a tithi is vriddha - long enough to cover two consecutive sunrises - and then two civil days both qualify. In that case the calendar lists the earlier day and adds a note naming both dates and saying which was chosen, rather than silently dropping one. The same rule and the same anchor are used for the Amavasya calendar, which is why the two behave alike; the Sankashti and Pradosh calendars use different anchors, because those rites are prescribed for moonrise and for the evening rather than for the day as a whole.
