Philippine presidents declared July 23 a special public holiday for Apolinario Mabini's birthday one year at a time, at least as far back as Ramon Magsaysay's Proclamation No. 45 of 7 July 1954. Proclamation No. 2367 made the holiday permanent for Batangas in 1984, and Republic Act No. 9430 attached the name Apolinario Mabini Day to a special working holiday in the City of Tanauan in 2007.
A holiday signed one year at a time
For decades no statute protected the date. Presidents signed the holiday into being one proclamation at a time, under section 30 of the Revised Administrative Code. The earliest one located is Ramon Magsaysay's Proclamation No. 45 of 7 July 1954, which gave the province of Batangas the day.
The habit outlasted him. Diosdado Macapagal signed one for the centennial in 1964. His proclamation asked for "appropriate ceremonies in tribute to the legacy he has left to the present generation".
