April 30 is the day of expelling the invaders from the southern sea of Iran. This day is celebrated in the Iranian calendar as the "National Day of the Persian Gulf". This day reminds us of the power, peace, greatness and unbreakable bond of the Iranian nation with the azure waters of the south. The Persian Gulf is not just a geographical location, but encompasses a large part of Iran’s thousand-year-old identity, history and civilization. This beautiful name shines with dignity and glory on all old maps. We congratulate all Iranians and the guardians of our sacred homeland on this important day. May God protect Iran and the glorious name of the Persian Gulf forever.
