How to add hours in time format

Hello Vinoth,

In angular, you can do like following:

let timeStr = "10:17";
let time = new Date();
time.setHours(Number(timeStr.substr(0, 2)) + 6);
time.setMinutes(Number(timeStr.substr(3)));
let updatedTimeStr = `${time.getHours().toString().padStart(2, '0')}:${time.getMinutes().toString().padStart(2, '0')}`;
console.log(updatedTimeStr) //16:17

Thanks

 JavaScript using the Date object and its setHours() method.

// Create a new Date object
var myDate = new Date();

// Add 2 hours to the current time
myDate.setHours(myDate.getHours() + 2);

// Convert the Date object to a string in time format
var timeString = myDate.toLocaleTimeString();

// Output the time string
console.log(timeString);

Hello Kumar,

To add 6 hours to a given time in the format of "hh:mm", you can use the following steps:

1. Convert the time string to a DateTime object in C#.

string time = "10:17";
DateTime datetime = DateTime.ParseExact(time, "HH:mm", CultureInfo.InvariantCulture);

2. Add 6 hours to the DateTime object using the AddHours() method.

datetime = datetime.AddHours(6);

3. Convert the DateTime object back to a string in the original format. 

string newTime = datetime.ToString("HH:mm");

The final code would look like this:

string time = "10:17";
DateTime datetime = DateTime.ParseExact(time, "HH:mm", CultureInfo.InvariantCulture);
datetime = datetime.AddHours(6);
string newTime = datetime.ToString("HH:mm");
Console.WriteLine(newTime);

This will output the new time with 6 hours added in the format of "hh:mm". In this case, the output will be "16:17".

Hello Vinot

Please check the below code to add hours in time.

DateTime dateTime = DateTime.ParseExact("10:17", "HH:mm",CultureInfo.InvariantCulture);
dateTime = dateTime.AddHours(6);
