Treat BS month lengths as data

The Bikram Sambat calendar is not converted accurately by adding a fixed number of years and months to an AD date. Month lengths vary, so this tool uses a bundled month-length table. Its supported range is BS 2000–2090. Requests outside that range need a different verified source rather than a guessed extrapolation.

Choose the BS year and month to generate a calendar. Each day also displays an AD month-day reference. The printable header states the AD start and end dates, which helps when a BS month crosses an AD month boundary. You can choose Nepali or English day numerals without changing the underlying dates.

Check a known date before using a schedule

BS 2083-01-01 corresponds to AD 2026-04-14, a Tuesday. BS 2083-07-01 corresponds to 2026-10-18. Under the bundled conversion table, AD 2026-10-28 is BS 2083-07-11. These examples make it easier to notice a wrong selected year or a date-format mix-up.

Write the calendar system beside dates in important records. A string such as 2083-07-11 should be labeled BS, while 2026-10-28 should be labeled AD. Do not assume that a receiving form interprets a date the same way as the calendar you are viewing.

Read holiday scope before planning a closure

The bundled holiday overlay is limited to dated records from the Ministry of Home Affairs notice for BS 2083. Some holidays apply to a region, community, institution or group. A named date in a list does not automatically mean every office, school or business closes.

The tool includes available scope notes on additional printable pages. Other supported years still have calendar dates, but no verified holiday overlay is claimed for them. Consult the official notice and relevant institution for changes or a decision that depends on a closure.

  1. Choose a supported BS year and month.
  2. Review the AD start date and first weekday.
  3. Inspect holiday notes and their scope for 2083.
  4. Download the calendar and any additional notes.
  5. Use the CSV when you need an explicit BS–AD mapping for the month.

Keep the export’s limits visible

A printed page is a snapshot of the bundled data. It will not change if an official notice is later amended. Record the source and check the current official notice before travel, an exam, a payment deadline or another important commitment.

The PDF uses rendered pages to preserve Nepali-script appearance. That is useful for visual consistency, but it does not create a fully structured, selectable-text calendar document. Keep the CSV for machine-readable date mapping. For a single date conversion, use the dedicated date tool and verify the calendar-system labels before copying the result into another application.
