Monthly trigger will start a build once a month at a specified time.

Time

The time when a build should be fired. Note that this property uses 24 hour format.

Repeat

Specifies which day of the month will fire a build. This field can be one of the following values:

• On day number: A build will be triggered on a specific day number. If this value is selected then the Day Number property must also be set.
• On the first: A build will be triggered on the first week of each month on a specific day. If this value is selected then the Day property must also be set.
• On the second:  A build will be triggered on the second week of each month on a specific day. If this value is selected then the Day property must also be set.
• On the third:  A build will be triggered on the third week of each month on a specific day. If this value is selected then the Day property must also be set.
• On the fourth:  A build will be triggered on the fourth week of each month on a specific day. If this value is selected then the Day property must also be set.
• On the last:  A build will be triggered on the last week of each month on a specific day. If this value is selected then the Day property must also be set.

Day Number

This property can only be set if Repeat is set to On day Number. This property sets the day of the month that a build should be triggered.

Note that if a month does not include a day number then a build will be executed on the last day of the month instead. For example, if your trigger fires a build on the 31st of every month, any months that have 30 days will instead trigger a build on the 30th.

Day

This property specifies the day that a build should be triggered. Note that this property is only available when Repeat is not set to On day number.

In the above example, a build will be executed on the first Sunday of every month.
