getUTCDate() — epoch day is 1

📖 Usage Example

const d = new Date('2024-06-15T12:00:00.000Z')
d.getUTCDate()  // → 15

Use getUTCDate() to retrieve the day of the month (1–31) in UTC, unaffected by the local timezone.

Date.prototype.getUTCDate()

The Unix epoch is January 1, 1970 UTC, so getUTCDate() returns 1.

Challenge: Verify that new Date(0).getUTCDate() returns 1.
