Date.prototype.setMinutes() changes the minutes (and optionally seconds and milliseconds) of a date in local time. It mutates the Date in place and returns the new timestamp.
date.setMinutes(minutes)
date.setMinutes(minutes, seconds)
date.setMinutes(minutes, seconds, ms)
minutes: 0 … 59 (local)
→ returns new timestamp (ms)
→ mutates date
setMinutes(45) // keep seconds/ms
setMinutes(45, 0, 0) // snap to :45:00.000
setMinutes(75) // overflow → +1 hour, :15Call date.setMinutes. Start with this line.
date.setMinutes(m[, sec[, ms]])| Call | What it does |
|---|---|
date.setMinutes(m[, sec[, ms]]) | Primary signature. |
date.setMinutes(...) | Call with the arguments your case needs. |
Built into JavaScript. Call setMinutes(...) on a Date instance — no import required.
date.setMinutes(m[, sec[, ms]])| Parameter | Description |
|---|---|
| minutesValue | Required. Local minutes (typically 0–59; overflow allowed) |
| secondsValue | Optional. Local seconds; keep current if omitted |
| msValue | Optional. Must also pass seconds if you pass ms |
| Return Value | Description |
|---|---|
| * | The value returned by date.setMinutes(). |
Change the minutes and keep the existing seconds.
const event = new Date(1975, 7, 19, 23, 15, 30);
event.setMinutes(45);
console.log(event.getMinutes()); // 45
console.log(event.getSeconds()); // 307 is August.setMinutes(45). Only the minutes argument is provided.30.event now reads minutes 45.Pass multiple arguments to snap to an exact local time within the hour.
const event = new Date(1975, 7, 19, 23, 15, 30);
event.setMinutes(45, 0, 0);
console.log(event.getMinutes()); // 45
console.log(event.getSeconds()); // 0
console.log(event.getMilliseconds()); // 0setMinutes(45, 0, 0) sets minute, second, and ms.Values outside 0–59 normalize into later hours.
const d = new Date(2026, 2, 15, 10, 30, 0); // Mar 15, 2026 10:30
d.setMinutes(75);
console.log(d.getHours()); // 11
console.log(d.getMinutes()); // 1510.75 = 60 + 15 → add 1 hour, keep minute 15.11; minutes become 15.Date.prototype.setMinutes() 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. Watch mutation, overflow into hours, and DST when adjusting local minutes. See also the MDN setMinutes() reference.
