Theravada Buddhist monks use zayats as their dwelling place while they are exercising precepts on Uposatha days.
Donors mostly build Zayats along main roads aiming to provide the exhausted travelers with water and shelter.
[1][2][3] Contributions, in money or labor, towards the construction, running or elaboration of a zayat are seen as dāna (meritorious charity).
For example, the Jivitadana Sangha Hospital for Buddhist monks and nuns began as a clinic at a zayat.
[6] Because of the importance of zayat based evangelism to Adoniram Judson's mission, and the prominence that his first wife Ann Hasseltine's letters gave his work, many Christian missionaries in Burma constructed and used one or more zayats, and their letters and journals were widely published by missionary boards and societies in the United States.
