// Import required packages

import java.util.Date;

// Compare two dates
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date date1 = sdf.parse("2023-07-01");
Date date2 = sdf.parse("2023-07-31");

if(date1.before(date2)) {
    // date1 is before date2

Date has before and after methods and can be compared to each other as follows:

if(todayDate.after(historyDate) && todayDate.before(futureDate)) {
    // In between
}
For an inclusive comparison:

if(!historyDate.after(todayDate) && !futureDate.before(todayDate)) {
    /* historyDate <= todayDate <= futureDate */ 
}
You could also give Joda-Time a go, but note that:

Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java.time (JSR-310).

Back-ports are available for Java 6 and 7 as well as Android.

for ( Map.Entry<DayOfWeek , LocalTime> entry : dayToTimeMap.entrySet () ) {
    DayOfWeek key = entry.getKey ();
    LocalTime value = entry.getValue ();
    int comparison = key.compareTo ( today );
    if ( comparison < 0 ) { // if earlier day…
        earlier.add ( key );
    } else if ( comparison == 0 ) { //If same day…
        if ( value.isBefore ( now ) ) {
            earlier.add ( key );
        } else {  // Else same time as now or later than now…
            later.add ( key );
        }
    } else if ( comparison > 0 ) {
        later.add ( key );
    } else {
        throw new RuntimeException ( "Unexpectedly reached IF-ELSE for comparison: " + comparison );
    }
}
