This is a simple base gem for calculating number of days stayed in a country (for nomads).

Resident status (for tax purposes), revolves around being in a country for more than 180 calendar days.

The way this script looks at it, as it monitors the last checkin.

This is ALPHA quality software

gem install dont-overstay

require 'dont-overstay'

d = Daytracker.new
# This accepts timestamps, otherwise it will by default return the last years
# before (check before a date or current date)
# after (check after a date or exactly 1 year ago)
puts d.query

gem build dont-overstay.gemspec
gem install dont-overstay-0.0.1.gem
