Perimon Download

The cycle calendar PERIMON exists in two versions; an online version (4.1) and the older DOS version. The DOS version was available for free since its release 2001, and it still is. However it comes with some limitations compared to the current online version: The calculation routines are not as extensive, it only runs on PCs with the Windows™ platform and the handling is much less comfortable than PERIMON 4.1. Also it doesn't include a conception mode.

If you like to, you can download the old PERIMON DOS by clicking the link below. The last update of PERIMON DOS to version 3.6.10 is safety relevant and leads to an improvement in contraception safety. Please upgrade your old version (version info).

...Or you directly head for the new PERIMON 4.1 that operates online, runs always on the most up-to-date safety standard and includes a real calendar (register here to start the free trial period).
