DateDiff

DateDiff does one thing, and one thing well: calculate the absolute differences, in days, between two dates of the exact format YYYY-MM-DD.

Usage

There are three ways to use datediff: a library, via the command line or as a server (either self-configured, or as a docker container).

Library

import (
    "github.com/Jeadie/DateDiff/diff"
)

days, err := diff.AbsoluteDateDifference("2020-02-20", "2002-02-20")
if err == nil {
	fmt.Printf("%d days\n", days)
}

Command Line

After installing (see install binary):

 datediff cmp 2020-02-20 2002-02-20

Server

For running from binary, after installing (see install binary):

datediff server -p=8001

(WIP): Or the server can be run as a Docker container:

docker run ...

Installation

Binaries are available for all releases, here, built across OSs and architectures.

curl -OL https://github.com/Jeadie/DateDiff/releases/download/v0.0.2/datediff-v0.0.2-darwin-amd64.tar.gz
tar -xzf  datediff-v0.0.2-darwin-amd64.tar.gz

# Binary can then be used as above, e.g. 
./datediff cmp 2020-02-20 2002-02-20
