Bhikkhunī Sangha Lunar Calendar Commemorative Dates,
2567-2568 BE | 2024-2025 CE 

Small Wheel_Base_Updating_Apr_16 copy.png

The calendar shows important days throughout the year for commemorating the Bhikkhuni Sangha and great Bhikkhuni foremothers, with the intention of bringing these dates into greater awareness and celebration. The calendar represents countless hours of research and effort, and is based on the historical research of Tathālokā Therī, with calendar design and artwork by Thāvirā Bhikkhunī. 

 

Please note, this is a lunar calendar, so while these dates will be consistent on the South & Southeast Asian Lunar Calendar widely used by Buddhists in these regions year after year, they will change on the western Gregorian calendar, just as with Vesak, Vassa, and other annual Buddhist holidays and commemorative dates which also follow the lunar calendar.

 

We plan to update the calendar for future years, and release around the time of the Astro-Solar New Year (mid-April). 

We currently have a very limited number of printed 16x20 posters of the calendar, please contact us if you wold like to receive one! 

This year, the printing of these posters has been made possible by a grant from the Lenz Foundation. 

Please contact us for information on printing your own copies of the poster, or if you would like to support additional printings now or in future years.
