Lunarium: Plans for the Future
1. Jonas Method calculations will be still more precise and they will work well no matter when the person was born (right now, the calculator doesn't work for thos born close to New Moon).
2. It will be very easy to add any new location to the list of the cities at Lunarium, you will be able to do that yourself.
3. You will be able to get lunar calendar for any month in the wide range of years, not just for 2006 - 2008. I think the range 1900 - 2020 will be available.
