Setting the Job Scheduling Time to the Last Day of Each Month

Scenario

When configuring job scheduling, you can set the scheduling time to the last day of each month using either of the two methods provided in the following table.

**Table 1** Setting the scheduling time to the last day of each month
Method	Advantage	Procedure
Set the scheduling frequency to every day and use a condition expression to determine whether a day is the last day of each month.	This method applies to multiple scenarios. You can compile condition expressions to flexibly schedule jobs, for example, on the last day or 7th of each month.	Method 1
Set the scheduling frequency to every month and select the last day of each month.	You can set a specific job scheduling time instead of compiling any statements.	Method 2

Method 1

In DataArts Studio, create a job that is scheduled every day and add an empty Dummy node (which does not process data) to the job. You can set a condition expression on the connection line between the Dummy node and its subsequent node to check whether the current day is the last day of the current month. If it is the last day, the subsequent nodes are executed. Otherwise, the subsequent nodes are skipped.

In the left navigation pane of the DataArts Factory console, choose Data Development > Develop Job.
Set Scheduling Frequency to Every day.
Figure 1 Setting Scheduling Frequency to Every day
Right-click the connection line between the Dummy node and its subsequent node and select Set Condition to configure a condition expression that is used to determine whether to execute the subsequent node.
Figure 2 Configuring a condition expression
Configure the expression as follows:
```
#{DateUtil.getDay(DateUtil.addDays(Job.planTime,1)) == 1 ? "true" : "false"}
```
The expression is used to obtain the current time and check whether the next day is 1st of a month. If yes, the current day is the last day of the current month, and the subsequent node will be executed; if no, the subsequent node will be skipped.

Figure 3 Condition expression

For example, if you want a job to be executed on the last day of each month, perform the above operations.

For example, if you want a job to be executed on the seventh day of each month, perform the following operations:

Configure the following expression to check whether the current day is 7th:
```
#{DateUtil.getDay(Job.planTime) == 7 ? "true" : "false"}
```

Method 2

In the left navigation pane of DataArts Factory, choose Development > Develop Job.
Click Scheduling Setup on the right of the job canvas.
Set Scheduling Type to Run periodically, Scheduling Frequency to Every month, and Select Time to the last day of each month.

After the scheduling time is configured, the job will be automatically executed on the last day of each month.
