Subtracts specified date period from this date and returns the new Date.

Subtracts number of days from this date and returns the resulting Date.

Subtracts number of months from this date and returns the resulting date.

Note: Day of month value of the resulting date will be truncated to the valid range of the target date if necessary.

This means for example, that date(2013, 3, 30).minusMonths(1) will return 2013-02-28, since February 2013 has only 28 days.

The indirect successor or predecessor at the given offset, where:

• x.neighbour(0) == x,
• x.neighbour(i+1) == x.neighbour(i).successor, and
• x.neighbour(i-1) == x.neighbour(i).predecessor.

Compute the offset from the given value, where:

• x.offset(x) == 0, and
• x.successor.offset(x) == 1 if x!=x.successor.

Returns the period between this and the given date.

If this date is before the given date then return negative period.

Returns the period between this and the given date.
