The list of methods to do LocalDateTime Calculate are organized into topic(s).

Method

LocalDateTimeadd(final LocalDateTime original, final int years, final int months, final int days, final int hours, final int minutes)
add 
return original.plusYears(years).plusMonths(months).plusDays(days).plusHours(hours).plusMinutes(minutes);
LocalDateTimeaddHeureMinute(final LocalDateTime time, final int heures, final int minutes)
add Heure Minute 
return time.plus(heures * 60 + minutes, ChronoUnit.MINUTES);
booleanareDatesOneMonthApart(LocalDateTime start, LocalDateTime end)
are Dates One Month Apart 
final int startDay = start.getDayOfMonth();
final int endDay = end.getDayOfMonth();
if (startDay == endDay && (start.getMonth() != start.getMonth())) {
    return true;
} else {
    final boolean startAtMonthEnd = (startDay == start.getMonth().length(start.toLocalDate().isLeapYear()));
    final boolean endAtMonthEnd = (endDay == end.getMonth().length(end.toLocalDate().isLeapYear()));
    if (startAtMonthEnd) {
...
LocalDateTimeatMidnight(LocalDateTime value)
at Midnight 
return value != null ? value.truncatedTo(ChronoUnit.DAYS) : null;
LocalDateTimebalanceStartAndEndDateTime(LocalDateTime startDateTime, LocalDateTime endDateTime)
Takes two LocalDateTime and balances by ensuring that the latter DateTime is gaurenteed to be later than the former DateTime 
LocalDateTime newEndDateTime = endDateTime;
while (startDateTime.compareTo(newEndDateTime) >= 1) {
    newEndDateTime = newEndDateTime.plusDays(1);
return newEndDateTime;
booleanbefore(LocalDateTime time1, LocalDateTime time2)
before 
return time1.isBefore(time2);
LocalDatecalcNextDayOfWeekFromLDT(LocalDateTime ldt, DayOfWeek dow)
Like it says 
LocalDate d = ldt.toLocalDate();
return calcNextDayOfWeek(d, dow);
LocalDateTimeceilDate(LocalDateTime dateTime)
Performs a "ceiling" operation on a LocalDateTime, and returns a new LocalDateTime with time set to 23:59. 
if (dateTime == null) {
    return null;
return dateTime.toLocalDate().atTime(23, 59);
booleancheckIfTimeExist(LocalDateTime date)
check If Time Exist 
LocalDateTime currentTime = LocalDateTime.now();
return currentTime.getHour() != date.getHour() || currentTime.getMinute() != date.getMinute();
LocalDateTimeclampDateTimeWithMaxAllowedHour(LocalDateTime dateTime, int maxAllowedHour)
Clamp the dateTime so that the latest hour can only be maxAllowedHour. 
if (dateTime.getHour() >= maxAllowedHour) {
    return dateTime.withHour(maxAllowedHour).withMinute(0);
return dateTime;
