Neyshabur Khayyam Day in Neyshabur
Neyshabur Khayyam Day marks the life of Omar Khayyam, the eleventh-century Persian mathematician, astronomer, and poet born in Neyshabur around 18 May 1048. Commemorations are traditionally held at his mausoleum in the city, where visitors gather to honor the man who designed the Jalali calendar and wrote the quatrains later known worldwide as the Rubaiyat.
Omar Khayyam was born in Nishapur, a major city of medieval Khorasan, in 1048, at a time when the region was a center of learning under the Seljuk Empire.
