You can use this utility class -

public class DateUtils
{
    public static final long SECOND_IN_MILLIS = 1000;
    public static final long MINUTE_IN_MILLIS = SECOND_IN_MILLIS * 60;
    public static final long HOUR_IN_MILLIS = MINUTE_IN_MILLIS * 60;
    public static final long DAY_IN_MILLIS = HOUR_IN_MILLIS * 24;
    public static final long WEEK_IN_MILLIS = DAY_IN_MILLIS * 7;
}

If you are working on Android framework then just import it (also named DateUtils) under package android.text.format

int day = 5;
long dayInMilliseconds = day * org.apache.commons.lang.time.DateUtils.MILLIS_PER_DAY
