ANSWER: Yoga Day
Explanation:
The UN postal agency, UN Postal Administration (UNPA) will issue the new special event sheet to commemorate Yoga Day that has been marked annually since 2015.
The special sheet comprises stamps with images of the sacred Indian sound “Om” and various yogic asanas. The UN stamps are issued simultaneously at UN offices in New York, Geneva and Vienna.
Each issue carries a design theme with different denominations for each office. Generally, six new commemorative issues are released each year and remain on sale for 12 months only.
The stamps illustrate the aims and achievements of the United Nations and the other organisations affiliated to it.
The UN General Assembly had adopted the resolution to commemorate the International Day of Yoga every year on 21 June in December 2014.
The resolution had been passed with the support of a record number of nations (177).
The first International Yoga Day was commemorated at the UN in 2015.
MEA Minister Sushma Swaraj had led the celebrations along with the then UN Secretary General Ban Ki-moon, spiritual yoga guru Sri Sri Ravi Shankar and US Congresswoman Tulsi Gabbard.
