When i try to update the os on my iPad from iOS 13.x to iOS 15.02 the screen message reads:
“Calculating remaining time. Update requested!”
This message never changes even after 12 night hours and despite good 4G WLAN connection with my iPhone. Therefore i can't upgrade my iPad to iOS 15.x.
What to do?
iPad Pro 12.9-inch Wi-Fi, Cellular

Here is the root of your problem; your iPad cannot be updated over a 4G Cellular hotspot connection. Update over cellular requires 5G.
Otherwise, your iPad can only be updated over a standard WiFi connection - or be updated by a PC or Mac using iTunes or Finder - over a USB connection. If performing the update using a PC/Mac, the computer must have an active internet connection with which to both download and verify the update package.
For your iPad to install an available update, its battery must be charged to at least 50% capacity - and/or be connected to its Power Adapter.

Your iPad is too far behind in iPadOS upgrades/updates.
If you have access to a full computer, like a Mac or Windows PC, try either using the Finder on a Mac that has the newest macOS Catalina installed OR with an older Mac with an older Mac OS, download and install the latest iTunes version ( or latest iTunes for Windows PC ), make sure the Mac or Windows PC is connected to the Internet, connect your iPad by the USB charge cable to the computer and let the iTunes application upgrade/update that iPad model, using the iTunes Software Update feature, to its current, maximum OS of iPadOS 15.0.2.
Make sure your iPad is, at least, charged to 50% or greater to attempt this.
Also, make sure to do a backup of your iPad's data, prior to upgrading/updating.
Backup to Apple iCloud and/or a full Mac or Windows PC using the same iTunes app OR, if a newer Mac running macOS Catalina, or later, making a backup using the macOS Finder app.
If NO access to a Mac or Windows computer, you will have to seek help from a good friend or family member, with a full Mac or Windows PC, to help you out
OR
Search online to locate and call contact your nearest, “local” Apple Store location to try/attempt to make an appointment to get your Apple iPad upgraded/updated to its latest iPadOS 14.6.
Apple Store employees will be glad to help/assist you.
Best of Luck to You!
iOS update
