@jmrozanec Thank you very much for your response! I am indeed using v7.0.4
My pom.xml includes:

    <dependency>
        <groupId>com.cronutils</groupId>
        <artifactId>cron-utils</artifactId>
        <version>7.0.4</version>
    </dependency>

The code you can use to replicate the problem is as follows (sorry, I see I copied the schedule expression incorrectly in my previous message...):

    String schedule = "0 0 * ? * SAT-SUN *";
    CronParser parser = new CronParser(cronDefinition);
    Cron quartzCron = parser.parse(schedule);

    CronDescriptor descriptor = CronDescriptor.instance();
    String description = descriptor.describe(quartzCron);
    System.out.println(description);

    ZonedDateTime time = ZonedDateTime.now();
    ExecutionTime executionTime = ExecutionTime.forCron(quartzCron);

    // Time from last execution to now
    Duration timeFromLastExecution = executionTime.timeFromLastExecution(time).get();
    System.out.println(timeFromLastExecution.toMinutes());
