kotlin 判断节假日

kotlin 编写函数判断节假日。节假日信息 获取

• 先判断是否是节日休息
• 再判断是否周六周日，且不是调休，才算做休息日
• 剩余的都是工作日

holiday

data class Holiday(
    // 节日名称
    val name: String,
    // 节日休息范围
    val dateRange: ClosedRange<LocalDate>,
)

fun holidays(date: LocalDate): Boolean {
    val holidays = listOf(
        Holiday("New Year's Day", LocalDate.of(2023, 12, 30)..LocalDate.of(2024, 1, 1)),
        Holiday("Spring Festival", LocalDate.of(2024, 2, 10)..LocalDate.of(2024, 2, 17)),
