The standard mental model for a date is based on three concepts - year, month and day. These map onto the YEAR, MONTH_OF_YEAR and DAY_OF_MONTH fields. Note that there is no reference to eras. The full model for a date requires four concepts - era, year, month and day. These map onto the ERA, YEAR_OF_ERA, MONTH_OF_YEAR and DAY_OF_MONTH fields.We have a java date object which is in a different timezone then the timezone of machine. We want to date, month and year of the date without changing the timezone. Also the function is unaware of the date's timezone. All it is getting is java date object with date in correct timezone and java Date does not provide Date.getTimeZone(). Also despite the name a Calendar object is more than a calendar date, it also carries with it a time of day, a time zone and more, so I do not consider it a good fit for the job at hand. The code using Calendar will give a different result if the default locale is Thai, which will surprise most.
The syntax is Date(year, month, day, hour, minute, second, millisecond). Note that the months are zero-indexed, beginning with January at 0 and ending with December at 11. Get a date and time from a timestamp const unixEpoch = new Date(0); This represents the time at Thursday, January 1st, 1970 (UTC), or the Unix Epoch time.
2 Answers. Edit: To get the months difference, you can use Calender class. Otherwise, use JodaTime library (linked at bottom of answer). Calendar startCalendar = new GregorianCalendar (); startCalendar.setTime (startDate); Calendar endCalendar = new GregorianCalendar (); endCalendar.setTime (endDate); int diffYear = endCalendar.get (CalendarLocalDate represents a date-only value without time-of-day and without time zone. Note that unlike the legacy classes, here the months have sane numbering 1-12 for January-December. Note that unlike the legacy classes, here the months have sane numbering 1-12 for January-December.
