I'm currently using Mozila Sunbird portable but I cant find a way to open it in Android..
Is there a portable cross platform calendar that can run in Windows and Android from a usb drive?

if you want access a calendar from windows and from Android, you can use google calendar and all is fine.
You can open it in a browser on every windows machine and also in android with many apps in playstore for that.
As Android is completely different operating system with own resources, even made for different processors, you can not install windows software on it.

Thanks for your input Otto.
But Google calendar is far from what I'm looking for.
I need a portable calender that's installed on a usb and online syncing is not an option.
There are a bunch of cross platform calenders out there but non have a portable version, that i can find.. .
you can not have windows software installed on android. Neither there is something like portable software for android. All need to be installed there and will not run from an usb stick. USB sticks can be handled by some android devices as storage, but far not by all. You need OTG capabilty on your andorid device to be able to access usb stick as storage media, but you will not be able to run any programs from there. Android might be able to 'move' some programs to the external SD card, but this is not so that all parts of the installation will now be on the external SD. Part of the program will still reside on the internal memory of the android device, thus transferring just the part on the external card to let say usb stick will not make it executable anyway and even not on other android device.
Simple: you can not install windows software on android. And you can not have 'portable' software for android.
You can go and start playing with some very experimental things like virtual windows on android, well try, but this is far from being useful for any practical purposes, it is just a kind of simulation some windows functions.
Opposite way, you can have android running in some virtual machine on windows. This is equally just a prove of concept. I have such thing here on my PC under VirtualBox running, but again, only basic functions of android are supported there, no practical use found so far for it.
What you need is database in the cloud, where two different software can equally well read it.
You could set up some owncloud server on some NAS or some other server and use clients for the respective operating system for it.
This what the 'cross platform' client software will offer you. Those are different clients using same database.

I understand that android can't run windows software and that it cant run portable apps.
Let me try and explain myself again..
What I'm looking for is a portable calendar that saves its entries in a separate file.
Then an android calendar app that can access that "separate file" from my usb and display all my entries.
Hope I'm a bit more clear this time...
Does anything like that exist and is it possible?
Thunderbird or Sunbird has an option to save as a CSV which then could open on Android with any app able to open a CSV or Excel like page not sure how the output would look but might bepossible

yes, one can export calendars also in .ics and also .html and import it to android, however as android uses for calendar purposes its own internal calendar service, all calendars for android are not self contained apps, but just front ends which can access this calendar service.
Which means it can *import* (not just open) calendar data to this database and one of its predefined sections. Mostly this is the google calendar, on some devices you will find also a kind of a local calendar, but not on all. Nobody bothers to design complete stand alone calendar for android, as this will have then no functionality apart from simply displaying data which can be achieved with excel sheet too.
What that means: one can import calendar data to google calendar, this is part of the android operating system. That is about all. Any calendar app can be used then, also the standard build in one.

does your android device support reading from external usb device at all?
Many do not, so you have to be sure first and have the OTG adaptor to set the android to host mode first.

Yes, my device supports OTG and I have an adapter.
I'm aware of the import/export features but that's not what I was looking for.
Thanks for all the suggestions. It doesn't look like what I need exists...
if someone will try to develop something like that, google will find a way stop that functioning with the next update...

I don't think Android can run apps that aren't installed, so it can't run something from USB.
Thunderbird + Lightning should be used over Sunbird these days. It's come a long way since then.
Sometimes, the impossible can become possible, if you're awesome!
