Remarks

Please make sure that you are using the right calendar object, since adding time is related with your calendar of choice. You can have more info on Calendar definitions by checking the $Calendar object.This method adds the given duration in business hours. If just need to add duration and find next business date time, please use Calendar.GetDateTime method instead.

Example

Using duration format

// Adds 1 month, 1 day, 2 hour
var newDate = $Calendar.StandardCalendar.AddTimeSpan($Calendar.Today, 'P1M1DT2H');

Example

Using time span format

// Adds 1 day, 2 hours, 30 minutes and 45 seconds to the current time.
var newDate = $Calendar.StandardCalendar.AddTimeSpan($Calendar.Today, '1.02:30:45');

Example

For 09:00-18:00 business hours, adding 2 hours to 17:00 results next day 10:00 not 09:00

var nextDate = $Calendar.AddTimeSpan(DateTimeOffset.parse('2023-02-08T17:00'), 'PT2H');
// nextDate will be set to '2020-02-09T10:00'

Example

//Adds exactly 1 day, 2 hours, 30 minutes and 45 seconds to the current time.
var newDate = $Calendar.StandardCalendar.AddTimeSpan($Calendar.Today, '1.02:30:45');
var newDate = $Calendar.StandardCalendar.AddTimeSpan($Calendar.Today, 'P1DT2H');
