BusinessHours and scheduled dates

Question

I am trying to create a payment schedule off of a input field DATE. If the date falls on a Weekend or on a Holiday then I want to move the payment date to the next open business day.

I was using the BusinessHours class to help me solve this but the business hours for the company takes into consideration the business hours. ha I know. I do not want to include the business hours, just the days. I also don't want to have to change the core business hours just to make this logic work.

For example: a user schedules a payment date of Monday at 5am. The business hours don't start until 7am. The logic will keep searching for the next available business day.

Is there a better class that only takes into consideration the business DAYS or should I work around the hours by pulling the DateTime, stripping the time (even though when I do this it still leaves a 00:00:00 time), and then pushing to the nextStartDate()?

Thoughts?

Here is some code I started:

public Datetime scheduler(String varFrequency, Datetime schedDateTime){
        BusinessHours bh = [SELECT Id FROM BusinessHours WHERE IsDefault = true];

        if (BusinessHours.isWithin(bh.Id, schedDateTime)){ //this will come up as FALSE if the time isn't between 7am - 6pm M-F
            schedDateTime = schedDateTime.addDays(1);
        } 
        else {
            schedDateTime = BusinessHours.nextStartDate(bh.Id, schedDateTime);
        }
}

Answer 1

You should change the method as below.

If schedDateTime is within business hour then no need to do alteration, otherwise, it will return the nearest next datetime.

Here nextStartDate will take two parameters BusinessHourId and input Datetime, as opposed to only BusinessHourId which you have used.

public Datetime scheduler(String varFrequency, Datetime schedDateTime)
{

    BusinessHours bh = [SELECT Id FROM BusinessHours WHERE IsDefault = true];

    if (!BusinessHours.isWithin(bh.Id, schedDateTime))
    { 
        return BusinessHours.nextStartDate(bh.Id,schedDateTime);
    }
    return schedDateTime;
}

public Date returnSchedulerDate(String varFrequency, Datetime schedDateTime)
{
    DateTime dt = scheduler(varFrequency,schedDateTime);
    return Date.newinstance(dT.year(), dT.month(), dT.day());
}
