How to solve this issue ?

Modify the following logic

maskito/projects/kit/src/lib/utils/date/append-date.ts

Lines 3 to 21 in 802972a

	export function appendDate(
	initialDate: Date,
	{day, month, year}: Partial<MaskitoDateSegments<number>> = {},
	): Date {
	const date = new Date(initialDate);
	if (day) {
	date.setDate(date.getDate() + day);
	}
	if (month) {
	date.setMonth(date.getMonth() + month);
	}
	if (year) {
	date.setFullYear(date.getFullYear() + year);
	}
	return date;
