When organizing Buddhist events or studying Buddhist culture, you often need to accurately convert dates between the Gregorian and Buddhist calendars. Based on the standard Theravada Buddhist algorithm (Gregorian Year + 543 = Buddhist Year), this tool provides precise two-way conversion between Gregorian and Buddhist dates. The output includes the complete date and the day of the week. The Buddhist calendar is an era system starting from the Parinirvana of the Buddha, widely used in Southeast Asian Buddhist countries.
How do you convert between the Buddhist and Gregorian calendars?
The algorithm adds 543 years to the Gregorian year to get the Buddhist year. For example, the Gregorian year 2024 corresponds to the Buddhist year 2567.
What input formats does the tool support?
It supports delimited formats like YYYY-MM-DD and YYYY/MM/DD. The system will automatically recognize the date digits for conversion.
Please ensure you enter the correct date format, otherwise the conversion may fail. This tool is based on the Theravada Buddhist standard calculation, which may differ from Mahayana Buddhist algorithms. The results only provide date conversion and do not include a Buddhist holiday lookup feature. All calculations are performed locally in your browser, ensuring your privacy is protected.
For academic research or religious event planning, we recommend verifying that your required Buddhist calendar standard matches the tool's algorithm. A typical conversion example: May 18, 2024 (Gregorian) converts to Saturday, May 18, 2567 (Buddhist), and vice versa. If you need to process historical dates, please note that the first year of the Buddhist calendar corresponds to 543 BCE.
