type fest cung cấp thêm các kiểu cho TS

// deno
import type { IntRange } from "https://deno.land/x/fest" 
// node
// import type { IntRange } from 'type-fest';

type Year = IntRange<2024, 2051>
type Month = IntRange<1, 13> /** The upper bound in IntRange is exclusive, so IntRange<1, 12> would not include 12. */
type Day = IntRange<1, 32>

Still, if you notice a decrease in performance, perhaps just splitting it out is best. For your convenience, here are the types for hour, day, month, year:

type Hour = 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23
type Day = 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31;
type Month = 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12
type Year = 2024 | 2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | 2035 | 2036 | 2037 | 2038 | 2039 | 2040 | 2041 | 2042 | 2043 | 2044 | 2045 | 2046 | 2047 | 2048 | 2049 | 2050 

It’s generated by this code:

console.log(new Array(30).fill(0).map((_, i) => i+2024).join(" | "))
