Date.prototype.getUTCDate() returns the day of the month (1–31) for a date in UTC (universal time). It is read-only and does not change the Date.
date.getUTCDate()
→ integer 1 … 31 (UTC calendar day)
→ NaN (if the Date is invalid)
getUTCDate() → day of month in UTC
getDate() → day of month in local time
getUTCDay() → weekday in UTC (0–6)Call date.getUTCDate. Start with this line.
date.getUTCDate()| Call | What it does |
|---|---|
date.getUTCDate() | Primary signature. |
date.getUTCDate(...) | Call with the arguments your case needs. |
Built into JavaScript. Call getUTCDate(...) on a Date instance — no import required.
date.getUTCDate()This method has no parameters beyond those shown in the signature.
| Return Value | Description |
|---|---|
| * | The value returned by date.getUTCDate(). |
Build a UTC instant with Date.UTC, then call getUTCDate().
const d = new Date(Date.UTC(2026, 2, 15)); // Mar 15, 2026 UTC
console.log(d.getUTCDate()); // 15Date.UTC(2026, 2, 15) means year 2026, month index 2 (March), day 15 in UTC.Date. new Date(...) stores that instant.getUTCDate() returns 15.Date is unchanged; getUTCDate only reads.Same wall-clock label with GMT+11 vs GMT-11 maps to different UTC calendar days.
const date1 = new Date("August 19, 1975 23:15:30 GMT+11:00");
const date2 = new Date("August 19, 1975 23:15:30 GMT-11:00");
console.log(date1.getUTCDate()); // 19
console.log(date2.getUTCDate()); // 2019.20.getUTCDate() when UTC is the contract.setUTCDate(getUTCDate() + n)Shift a UTC date forward; overflow rolls into the next month in UTC.
const future = new Date(Date.UTC(2026, 0, 28)); // Jan 28, 2026 UTC
future.setUTCDate(future.getUTCDate() + 7);
console.log(future.getUTCDate()); // 4
console.log(future.getUTCMonth()); // 1 (February)getUTCDate() is 28.setUTCDate(28 + 7) asks for UTC day 35 of January.getUTCDate() is 4; UTC month index is 1 (February).Date.prototype.getUTCDate() has been in JavaScript since ES1. It is Baseline and works in every modern browser and Node.js — no polyfill needed.
Supported everywhere Date exists: Chrome, Firefox, Safari, Edge, Internet Explorer, and all Node.js versions.
Bottom line: Safe to use in any environment. Focus on UTC vs local correctness. See also the MDN getUTCDate() reference.
