Word
dayOf
The calendar day of a moment in a time zone. With no zone it is the zone of the project.
Example
TypeScript
const day = dayOf(order.placedAt, 'Europe/Istanbul')Returns
The day, as '2026-10-08'. A day answers itself, and nothing answers nothing. With no zone it asks the engine: where a definition is being made it answers its record.
Errors
code.T0027: a value of another kind than the word works with, or a value past the limit valueSize.
code.T1014: a zone that is written and that the runtime does not know, when the project is described.
