Solar and Lunar Time in Nepal

Nepal uses two calendar systems side by side: the international Gregorian (English) calendar and the Nepali calendar called Bikram Sambat (वि.सं.), which is also commonly known as the Nepali Patro. The Gregorian calendar is a solar calendar. Its months have fixed lengths, ranging from 28 to 31 days, and its year is organized to remain aligned with the seasons.

The Nepali calendar, by contrast, follows the Bikram Sambat system. It is approximately 56 years and 8½ months ahead of the Gregorian calendar. The Nepali New Year begins in the middle of April, usually around April 13 or 14. Unlike the Gregorian calendar, the lengths of Nepali months are not fixed in advance. They may vary from year to year and usually range from 29 to 32 days. For this reason, Nepali dates do not correspond exactly to English dates month by month.

In everyday life, both calendar systems are important. Gregorian dates are commonly used for international communication, travel, passports, and global business. Bikram Sambat dates, however, are widely used within Nepal in schools, government offices, newspapers, calendars, and daily social life. In many contexts, both systems appear together.

This difference is especially noticeable in festivals and religious observances. Many important Nepali festivals are determined by lunar timing, often explained through tithi, or the lunar day. As a result, festival dates change each year on the Gregorian calendar. A festival that falls on one English date in one year may fall on a different English date the next year.

For learners of Nepali language and culture, it is useful to understand both systems. Knowing the names of Nepali months, recognizing that Bikram Sambat is significantly ahead of the Gregorian calendar, and understanding that many festivals follow lunar timing will make it easier to read schedules, understand notices, and participate in everyday conversations about time in Nepal.
