Narrative:

We took over a running aircraft and flew it on 3 flts. We made the incorrect assumption that the FMS database was current. I was unaware at the time that it was possible to check the FMS database date any other way than on powering up the aircraft. The next day I powered up the aircraft and discovered the database was out of date and had been out of date the previous day. I called maintenance and deferred the FMS; but I had already flown the previous day unaware of the breach in the FMS database date.
