Verify whether the number of minutes aligns with a full hour mark (60, 120, 180, 240 minutes, etc)

Query

Determine if a given number of minutes equates to an exact hour or multiple hours.

Scenario

I am currently working on a script where I need to ascertain whether a certain number of seconds corresponds to an hour or x hours; returning true if it does, otherwise false.

Although I do not have any code samples to offer at the moment, this is something I am attempting to solve.

I am aiming to create a function that simply validates if the input minute count aligns with exactly one hour or multiple-hour intervals. This could be 1 hour, 2 hours, 3 hours, and so forth.

The objective is not to calculate the actual number of hours but merely determine if the minutes provided match up precisely to the equivalent of an hour.

Anticipated Workflow Examples

The minute number will be defined as a constant/variable input (e.g., 59, 60, 120, 300, 673)

If Minute Number falls within 0-59, return false

If Minute Number is exactly 60, return true (since this would constitute 1 Hour)

If Minute Number ranges from 61-119, return false

If Minute Number equals 120, return true (indicating exact 2 Hours)

If Minute Number lies between 121-179, return false

If Minute Number indicates 180, return true (representing exact 3 Hours)

...and so on, endlessly - validating true for any exact instances of minute equaling an hour, and false otherwise.

Potential Approach Considered

I speculate that verifying if the minute number is divisible by 60 may be a viable starting point, however, I am unsure.

I hope someone can assist me with solving this issue. Thank you in advance.

Did you know the modulo (%) operator is what you need?

function IsMultipleOfFive(num) {
  return num % 5 == 0
}

console.log(IsMultipleOfFive(14))
console.log(IsMultipleOfFive(15))
console.log(IsMultipleOfFive(20))
console.log(IsMultipleOfFive(25))

This code snippet will output:

false
true
true
true
