A lunar calendar is based on the movements of the Moon. It is a general description of a type of calendar. There are many lunar calendars. The Gregorian Calendar is one particular calendar. It was established by Pope Gregory XIII, who introduced it in 1582. It is the calendar that much of the world now uses.

The Gregorian calendar is a solar calendar based on the Earth's orbit around the Sun, with months of fixed lengths. The lunar calendar is based on the cycles of the Moon and has months of varying lengths, making it around 11 days shorter than the Gregorian calendar year. This leads to differences in how dates are calculated and the timing of religious or cultural events.
Ramadan is based on the Islamic lunar calendar because the lunar year is about 10-12 days shorter than the Gregorian calendar, which is based on the solar year. This causes Ramadan to shift by about 10-12 days earlier each year in the Gregorian calendar.
The difference is the accuracy of mathematical computation of the length of the day, in essence. The Roman calendar was fairly accurate (considering the computation tools of the time, quite accurate), but over a period of many years, it was off by a period of (then) ten days. The Gregorian calendar proposal used more precise mathematics, and deduced that the calendar had lost ten days since the calendar of Rome was established. The calendar was jumped forward ten days (it's a long story). The current (Gregorian) calendar is accurate to about one day every several thousand years.
As the moon revolves around the Earth, and the Earth revolves around the Sun. I would guess you'd be 28.
The Jewish calendar consists of twelve lunar months. It also keeps in step with the solar year, by adding a thirteenth lunar leap-month seven times every nineteen years. The Gregorian calendar, which sticks to the solar year, ignores the lunar months and does not attempt to keep in step with them.

The United States uses the Gregorian calendar, which is a solar 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.

The Oriya calendar for 1971 corresponds to the years 1892-1893 in the Gregorian calendar due to the difference in the starting point of the two calendars. The Oriya calendar is based on the Hindu lunar calendar and follows the traditional Indian system of timekeeping.
The Jewish calendar is based on both the moon and the sun. A month can have 29 or 30 days (to start each month with a new moon), and there can be 12 or 13 months to a year. In every 19 years, 12 of the 19 years have 12 months, while seven have 13 months, thus keeping in line with the solar calendar and making every 19 years on a Jewish calendar exactly equal to 19 years on the Gregorian calendar.
