- Avoid Early Morning and Late Night: You should avoid calling late at night and early in the morning, as this might not be a convenient time for your recipient.
- Avoid calling at lunchtime: In Ireland, people do not prefer to receive calls during the break hours, i.e., around 12:00 PM to 2:00 PM.
