Why people convert Vienna to CET time

Scheduling a call from Vienna to CET: a 10:00 AM start in Vienna lands at 9:00 AM in CET, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Vienna and CET are inside the 9-to-5 working day between 10:00 AM and 5:00 PM CEST time (9:00 AM–4:00 PM CET). That is roughly 7 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Vienna is 7:00 PM in CET makes it easy to avoid calling at 3 AM.
