Omar Khayyam’s commemoration day

In Iranian Jalali calendar, today, Ordibehesht 28, is Omar Khayyam’s commemoration day. Omar Khayyam was a Persian mathematician, astronomer, philosopher, and poet.

Khayyam was born in Nishabur, in northeastern Iran in May 18, 1048. As a mathematician, he is most notable for his work on the classification and solution of cubic equations, where he provided geometric solutions by the intersection of conics. Khayyam also contributed to the understanding of the parallel axiom. As an astronomer, he designed the Jalali calendar, a solar calendar with a very precise 33-year intercalation cycle.

Khayyam is one of the best known Persian poets in world where a lot of English readers are also attracted to his poems. His poetry became widely known to the English-reading world in a translation by Edward FitzGerald, which enjoyed great success in the Orientalism of the fin de siècle.

Yon rising Moon that looks for us again –
How oft hereafter will she wax and wane;
How oft hereafter rising look for us
Through this same Garden – and for one in vain!

Omar Khayyam

World Migratory Bird Day

In 2006, the United Nations established World Migratory Bird Day to be held on the second weekend of May every year. The event was founded as an effort of the UN’s Agreement on the Conservation of African-Eurasian Migratory Waterbirds to raise awareness of the migratory linkages between regions of the globe. World Migratory Bird Day events have been held in 118 nations. Each year, the United Nations announces a uniting theme for official events.

It’s important to raise people’s knowledge about migrant birds as many of them are in danger of extinction or at least the loss and destruction of their habitats.

For example, “Omid” (literally means Hope in Persian) is the last Siberian crane that wings his way to Iran for years in the first week of the Iranian calendar month of Aban falling on the last week of October. Every year, there are concerns about the extinction of this very special migratory bird as it’s the only survivor of this species.
