UKismetMathLibrary::GetDay

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the day-of-month component of A as an integer in the range 1–31. Use this when you need to display or compare individual date components.

Caveats & Gotchas

• The return value is 1-based (1 = first day of the month), not 0-based. Subtracting 1 before indexing an array is a common off-by-one mistake.
• The valid range depends on the month and year — February in a non-leap year has a maximum of 28. If A was constructed with an out-of-range day, FDateTime clamps or wraps the value; the returned day may not match what you passed to the constructor.
