Is “First Day of Week” (System date) configurable or always Sunday?

Hi everyone,

In Logic Blocks we can use the System dates “First Day of Week” and “Last Day of Week”.
In any of my tenants, First Day of Week always resolves to be a Sunday date.

Before I design date logic around this, I’d like to clarify:

  1. Is the day of the week used for “First Day of Week” system value configurable anywhere at tenant / environment level (e.g., via settings, locale, or calendar configuration)?

  2. Or is Sunday a hard-coded platform default for “First Day of Week” that should be treated as fixed and not expected to change in the future?

I’m planning to use this value as an anchor for week-based calculations, so I want to make sure I’m not relying on behavior that could later be changed by configuration or by a platform update.

Thanks in advance for any guidance or documentation pointers.

@lpopovici we use Java’s Calendar class to get relative date values like first/last day of the week. There is no other way to configure them today, so it should be safe to rely on Sunday not changing .
