Solar and Lunar Time in Nepal

Nepal uses two calendar systems side by side: the international Gregorian calendar and the Nepali calendar, called विक्रम संवत् (bikram sambat), often written as वि.सं. (wi.saṃ.). The Nepali calendar is also commonly called the नेपाली पात्रो (nepālī pātro).

The Gregorian calendar is a solar calendar. Its months have fixed lengths, from 28 to 31 days, and the year is organized to stay aligned with the seasons.

The Nepali calendar follows the विक्रम संवत् (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, Nepali month lengths are not fixed in the same way. They may vary from year to year and usually range from 29 to 32 days. For this reason, Nepali dates do not match English dates exactly from month to month.

Two Calendars in Everyday Life

Both calendar systems are important in Nepal. Gregorian dates are commonly used for international communication, travel, passports, visas, and global business.

विक्रम संवत् (bikram sambat) dates are widely used within Nepal in schools, government offices, newspapers, calendars, and daily social life. In many contexts, both dates appear together.

For example, a school notice, official document, or public event announcement may include both the Nepali date and the Gregorian date.

Festivals and Lunar Timing

The difference between the two systems is especially noticeable during festivals and religious observances. Many important Nepali festivals are determined by lunar timing.

A key term is तिथि (tithi), which means a lunar day. Because many festivals follow the lunar calendar, their 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.

This is why festivals such as दशैं (daśaĩ), तिहार (tihār), होली (holī), and other religious observances do not always appear on the same Gregorian date each year.

Why This Matters for Learners

For learners of Nepali language and culture, it is useful to understand both calendar systems. Knowing the names of Nepali months helps you read schedules, understand notices, follow festival dates, and talk about time in everyday conversation.

It is also helpful to remember three basic points:

Nepal commonly uses both the Gregorian calendar and विक्रम संवत् (bikram sambat).

विक्रम संवत् (bikram sambat) is approximately 56 years and 8½ months ahead of the Gregorian calendar.

Many Nepali festivals follow lunar timing, so their Gregorian dates change each year.
