Within a few days. The 19-year cycle, based on various factors, can contain 6,939, 6,940, 6,941 or 6,942 days. After thirteen 19-year cycles, i.e., 247 years, the calendar returns very close to its initial value. But the 247-year cycle, too, is inexact. It is short by about 3016.67 seconds or about 50.278 minutes.

How closely does the Jewish calendar coincide with the solar calendar every 19 years?

Jewish calendric sources state that after each 19 year cycle the Jewish calendar regresses (i.e. you have to add) 2 days, 16 hours, 595 chalakim (about 1/2 hour). After each 247-year cycle, the calendar returns to the same calculations as the beginning of the previous 247-year cycle, with a regression of just 905 chalakim (about 52 minutes).

What is the major difference between the Jewish calendar and the Gregorian calendar?

The Gregorian calendar is a purely solar calendar, while the Jewish calendar is a solar-lunar calendar. In a bit more detail, the Gregorian calendar has months that have nothing to do with the moon and a leap day is added in February every few years to keep the days and months in their right season. In the Jewish calendar, every month starts with the new moon and a leap month is inserted (by doubling the spring month of Adar) when needed to keep the months in their right season.

On the secular calendar when is Purim celebrated?

It is different every year. It is always on the 14th (or 15th in a few cities) of Adar, a Jewish month. The Jewish months are calculated based on a lunar cycle designed to stay in sync with the solar calendar, unlike the calendar used in America which is purely solar. Because of this, the dates are different every year.
