Declarative pipeline

pipeline {

    stages {
        stage('Build') { steps { echo 'Scheduled build' } }
    }
}

The Jenkins fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).

If you set both day-of-month and day-of-week, Jenkins runs when either matches.
Use H instead of a fixed minute to spread load. H 2 * * * means "once during the 2 AM hour", at a stable per-job minute.
Jenkins uses the controller's time zone. Put TZ=Asia/Kolkata on its own first line of the trigger to override it.

The month field is 1-12 (January is 1), and the day-of-month field starts at 1, not 0.
