Filipino architecture often considers certain days lucky for beginning construction. Which of these is considered unlucky?

In Filipino culture, certain days of the week are associated with beliefs regarding luck and auspiciousness, especially in the context of home building and construction. Among these days, Friday is typically viewed as an unlucky day for starting construction projects. This belief stems from traditional practices and cultural superstitions, which can vary across regions but often hold that projects initiated on a Friday may encounter difficulties or fail to succeed.

The other days listed—Monday, Saturday, and Sunday—do not carry the same negative connotations in the context of beginning construction, often being seen as more favorable options. For instance, Monday is frequently viewed as a fresh start to the week, while Saturday and Sunday, being part of the weekend, are more associated with rest and planning rather than superstitions related to building projects. This cultural context helps to explain why Friday is singled out as unlucky for construction efforts.
