isWorkTime

checks whether the specified date is working or not

boolean isWorkTime(object | Date config);

config

object | Date

either the configuration object of a time span or a specific date

boolean

true, if the specified date is working time. Otherwise, false

Example

//checks whether the specified date is a working day in global settings
gantt.isWorkTime({ date: new Date(2023,3,5) });
// or
gantt.isWorkTime(new Date(2023,3,5));
 
//checks whether the specified date is working day for a specific task
gantt.isWorkTime({date: new Date(2023,3,5), task: task});

Details

If the work_time option is disabled, the method always returns true.

The method will use the global work time calendar if no task is specified.
Besides, the method can be called directly from a calendar object.

Let's assume that you set the following working time for the chart:

Working days: Monday - Friday
Working hours: 6:00 - 15:00

Then, if you check Monday April,3 2023 as in, you will get:

gantt.isWorkTime({date: new Date(2023,3,3,17,00), unit: "hour"}); 
//->false, cause 17:00-18:00 is not working time
 
gantt.isWorkTime({date: new Date(2023,3,3,17,00), unit:  "day"}); 
//-> true, cause Monday is a working day

Configuration object properties

The configuration object can contain the following properties:

date - (Date) a date to check
unit - (string) optional, a time unit: "minute", "hour", "day", "week", "month", "year"
task - (object) optional, the object of the task the duration of which should be calculated

if (gantt.isWorkTime({date: date, task: task})){
    alert("worktime of task" + task.text);
}
