ArcaOS 5.0 Support & Maintenance subscriptions are metered 1:1 to ArcaOS licenses (one ArcaOS 5.0 license is covered by one ArcaOS 5.0 Support & Maintenance subscription).

Visit the Arca Noae website (see link below) and log in. Select the link for Account, and then for Orders and Subscriptions. Look for your original ArcaOS order. That will show your original order date, from which you may be able to calculate your expiration date.
