Why people convert Dublin to Dubai time

Finding shared working hours: both Dublin and Dubai are inside the 9-to-5 working day between 9:00 AM and 2:00 PM IST time (12:00 PM–5:00 PM GST). That is roughly 5 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Dublin is 11:00 PM in Dubai makes it easy to avoid calling at 3 AM.
