## Operators on the Date Class

### Description

Operators for the `"Date"` class.

There is an `Ops` method and specific methods for `+` and `-` for the `Date` class.

### Usage

    date + x
    x + date
    date - x
    date1 lop date2

### Arguments

`date` | date objects
`date1, date2` | date objects or character vectors. (Character vectors are converted by `as.Date`.)
`x` | a numeric vector (in days) or an object of class `"difftime"`, rounded to the nearest whole day.
`lop` | One of `==`, `!=`, `<`, `<=`, `>` or `>=`.

### Details

`x` does not need to be integer if specified as a numeric vector, but see the comments about fractional days in the help for `Dates`.

### Examples

    z + 10
    z < c("2009-06-01", "2010-01-01", "2015-01-01")
