Temporal.Duration.prototype.hours

The hours accessor property of Temporal.Duration instances returns an integer representing the number of hours in the duration.

Unless the duration is balanced, you cannot assume the range of this value, but you can know its sign by checking the duration's sign property. If it is balanced to a unit above hours, the hours absolute value will be between 0 and 23, inclusive.

The set accessor of hours is undefined. You cannot change this property directly. Use the with() method to create a new Temporal.Duration object with the desired new value.

Examples

Using hours

const d1 = Temporal.Duration.from({ hours: 1, minutes: 30 });
const d2 = Temporal.Duration.from({ hours: -1, minutes: -30 });
const d3 = Temporal.Duration.from({ days: 1 });
const d4 = Temporal.Duration.from({ hours: 24 });

console.log(d1.hours); // 1
console.log(d2.hours); // -1
console.log(d3.hours); // 0
console.log(d4.hours); // 24

// Balance d4
const d4Balanced = d4.round({ largestUnit: "days" });
console.log(d4Balanced.hours); // 0
console.log(d4Balanced.days); // 1
