From July 1, annual periodicity only available on GeaCron Premium

The annual periodicity of historical maps will only be available on GeaCron Premium

We want to thank you for the interest you have shown on our website over the last six years.

Due to performance reasons, starting July 1, 2017, the complete annual sequence of maps, from 3000 BC to the current date, will be displayed only in GeaCron Premium. The free website will display just a limited number of maps for the same time range.

We hope GeaCron Premium will be a great help for you to focus your studies of Universal History in a very simple way and with a broad and rigorous vision.

And we will appreciate your support, which will allow us to continue our efforts to offer you the best version of this interesting tool.
