What Is the Nepali Calendar?
The Nepali calendar—locally called Nepali Patro—is the country’s official civil calendar, known internationally as Bikram Sambat (Wikipedia). Unlike the purely solar Gregorian system, Bikram Sambat is a lunisolar calendar: it tracks both the moon’s phases and the sun’s position against the stars. As a result, years are about 56–57 years ahead of the Gregorian year count. For example, mid‐April 2025 in Nepal marks the start of 2082 BS, not 2025 AD.
Action Tip: Bookmark a reliable conversion chart—like the one at NepaliCalendar.rat32.com—to check any date on the fly.
History of Bikram Sambat
Bikram Sambat dates back to 57 BCE, when King Vikramaditya of Ujjain is said to have defeated the Sakas. Nepal adopted his era in the 10th century CE as the official state calendar. Over centuries, it blended Hindu traditions (like lunar tithis) with solar festivals, becoming the backbone of Nepalese civic life—from royal decrees to school timetables (Wikipedia).
Action Tip: To appreciate cultural continuity, attend a New Year celebration in Kathmandu around April 14th and compare dates on wall calendars versus your phone.
How the Calendar Works: Lunisolar System
Lunisolar means months follow lunar cycles (new moon to new moon), but the calendar also inserts extra days or months to stay aligned with the solar year. A typical lunar year (12 months) falls about 11 days short of the solar cycle, so every few years an additional Adhik Maas (leap month) is added—much like the February 29 in Gregorian leap years.
Action Tip: Track the next Adhik Maas online via TimeandDate.com to see which Nepali year has an extra month.
Conversion to Gregorian Dates
To convert a Bikram Sambat year to a Gregorian one, subtract 56 or 57 years, depending on the date. From mid‐April to December, subtract 57; from January to mid‐April, subtract 56. For example, 1 Baisakh 2082 BS (April 14, 2025) equals April 14, 2025 AD—but 1 Magh 2082 BS (January 15, 2026) equals January 15, 2026 AD (Wikipedia).
Action Tip: Build a simple spreadsheet: list BS dates in one column, then use an IF formula to subtract 57 or 56 based on the month.
Months of the Nepali Calendar
There are 12 months, each varying between 29 to 32 days:
- Baisakh (Apr–May)
- Jestha (May–Jun)
- Ashad (Jun–Jul)
- Shrawan (Jul–Aug)
- Bhadra (Aug–Sep)
- Ashwin (Sep–Oct)
- Kartika (Oct–Nov)
- Mangsir (Nov–Dec)
- Poush (Dec–Jan)
- Magh (Jan–Feb)
- Falgun (Feb–Mar)
- Chaitra (Mar–Apr)
Action Tip: If you’re planning an event, choose a Baisakh or Kartika date for reliable weather.
Leap Months and Years
When the lunar months drift too far from the solar seasons, an extra month—Adhik Maas—is inserted, typically between Ashwin and Kartika. This keeps religious festivals in their proper seasons. Roughly every 2.5 years, Nepal adds this leap month, extending the year to 13 months (TimeandDate).
Action Tip: Check for Adhik Maas to avoid scheduling weddings or public holidays during this “extra” period.
Nepali New Year: Baisakh 1
Nepali New Year falls on Baisakh 1—usually April 14th. Streets fill with parades, music, and family gatherings. Schools and offices close as communities welcome the new year with prayers and cultural shows (Wikipedia).
Action Tip: Plan travel to Nepal for mid-April to witness Baisakh celebrations and use the Patro to join local festivities.
Major Festivals on the Calendar
Key festivals include Dashain (Ashwin), Tihar (Kartik), Holi (Falgun), and Teej (Bhadra). Each aligns with specific lunar tithis—dates counted from the new moon—so they shift on the Gregorian calendar each year (NepaliPatro).
Action Tip: Subscribe to an online Nepali festival calendar—like Hamro Patro (HamroPatro)—for automatic reminders.
Using the Nepali Calendar Today
While official offices use Bikram Sambat for legal and administrative purposes, many Nepalese households maintain both calendars side by side. Invitation cards, newspapers, and government forms all feature dual dates—the BS year first, then AD (Wikipedia).
Action Tip: If you’re in Nepal, always carry a tiny printed Patro in your wallet or use a multilingual calendar app to avoid confusion.
Digital Tools and Apps
Popular apps include Ramro Patro (Android/iOS), EasyNepaliTyping’s calendar converter, and built-in widgets on Hamro Patro’s website. They offer date conversion, festival alerts, and customizable reminders (Ramro Patro).
Action Tip: Download at least two apps (one for Android, one for iOS) so you can compare conversion accuracy on the go.
Cultural Significance
For Nepalese of all ethnic groups, Bikram Sambat is more than dates—it’s heritage. From planting crops at Chaitra to honoring ancestors during Pitrupaksha (Ashwin), the calendar guides life’s major milestones, weaving time into tradition (Nepal Sambat Wiki).
Action Tip: When attending local ceremonies, ask elders about the “tithi” (lunar day) to understand the deeper meaning behind celebrations.
Practical Tips for Travelers
If you’re visiting Nepal, note that many small businesses—guesthouses, rural markets—follow BS dates for holidays. Plan ahead around Dashain and Tihar when transportation and services may be limited (TimeandDate).
Action Tip: Schedule buffer days around major Nepali public holidays to avoid travel disruptions.
How to Make Your Own Conversion Table
Create a two-column table: column 1 lists Baisakh 1 of each BS year, column 2 lists its Gregorian equivalent. Use a base pairing—say, Baisakh 1, 2082 BS = April 14, 2025—and add 1 year = +1 in both columns, adjusting for leap years manually.
Action Tip: Share your conversion table as a PDF or printout for friends and family new to Nepali timekeeping.
The Future of the Nepali Calendar
With digital transformation, the Bikram Sambat calendar is going online. Government portals now accept BS dates for applications, and blockchain-based “time stamps” are being piloted for land records. Expect even tighter integration between BS and Gregorian systems (NepaliCalendar.rat32.com).
Action Tip: Follow Nepal’s Department of Information Technology updates to stay ahead of e-governance calendar changes.
