areMonthDaysEqual

Unreleased

Not in @northguild/gmt 1.20.0 on npm yet. It is on main and ships in the next release.

Signature

areMonthDaysEqual(a: string, b: string): boolean

Check whether two month-day strings (--MM-DD, or MM-DD) name the same day of the year.

• Accepts both input forms, so 12-25 and --12-25 are equal.
• The year is not part of a month-day: --02-29 is not equal to --02-28.
• Returns false if either input is invalid or not in the ISO calendar.

Parameters

Parameter	Type	Description
a	string	month-day string
b	string	month-day string

Returns

true only when both are valid and name the same month and day, or false on invalid input
