July 28 in each year commemorates the day that Peru gained its independence. General José de San Martín, known as Peru's liberator, proclaimed Peru's independence on this date. At dawn on the 28th a 21 cannon salute begins flag-raising ceremonies as Peru remembers the anniversary of its independence. Use of the flag 

During the whole month of July, homes, office buildings, public and private institutions, schools, and restaurants display the national flag. It is obligatory and it is rare to see any of these places without a flag. Regarding the President 
The President of Peru fulfills one of his major obligations during these days. In his capacity as Head of State he must, on July 28 of each year, give an accounting of the nation's progress up to this date. This Peruvian custom was established by José de San Martín. Te Deum Mass 
On the morning of July 28, the Archbishop of Lima celebrates the Mass of the Te Deum as mandated by the Catholic Church. Originally, the Mass was celebrated on July 29 but was later changed to its present date. The President, other government officials, and ranking dignitaries attend the service. The Mass officially begins at 9:00 A.M. Invitation of the President of the Republic 
On the morning of July 28 representatives of the Congress of the Republic of Peru go to the Government Palace to invite the President to give the traditional Address to the Nation. The delegation of the Peruvian Legislature can be led by any congressman or by the President of the Congress. Route to the Congress 
Once he has been invited, the President leaves by car headed toward the seat of Congress or, rarely, on foot. The nation's leader will sometimes choose to travel in a closed limousine or in a car with an open roof. It is common on this route for the President's supporter's to accompany him throwing flowers and shouting praises. During the presidency of Alan García Pérez the trip was always made in an open car. Once he arrives at the seat of the legislature he enters through the Hall of the Lost Footsteps where the Commander in Chief of the military detachment pays his respects to his high position. The President then enters the main room where he finds the general assembly. Address to the Nation 
Following the introductions, the President begins with his Address to the Nation for the National Holidays giving his accounting of the developments of the state during the year. The President discusses developments in projects economical, social, and cultural achievements as well as others. However, it is not uncommon for these accomplishments to be exaggerated. Return to the Government Palace 
Once finished with his address the President returns to Government Palace (commonly referred to as the House of Pizarro) to continue with other official ceremonies. July 29
