@govph clarified that Monday, 13 June 2011 is a working day. In previous regimes, the government practiced holiday economics. Should the holiday fall on a Sunday, then the following Monday will be a holiday. The administration of President Aquino has done away with holiday economics. Independence Day is celebrated on June 12. The 13th of June is a regular working day.
The government also clarified that 20 June is a holiday. This is in commemoration of Jose Rizal’s 150th Birthday.
