Call United Kingdom from Portugal

When calling internationally, it's important to consider time zone differences to ensure you're calling at a convenient time.

Portugal operates on Western European Time (UTC+0, or UTC+1 during daylight saving from late March to late October), making it ideal to call during their business hours of 9 AM-6 PM, which translates to early morning if you're in the Americas or evening if you're in Asia or Australia. Keep in mind that Portugal follows EU daylight saving rules, so always verify the current time difference during the transition periods in March and October to avoid calling too early or late. When calling the United Kingdom, which operates on GMT (UTC+0) in winter and BST (UTC+1) in summer, aim for late morning to early afternoon your time if you're calling from the Americas, or early evening if calling from Asia to catch UK business hours (9 AM-5 PM). Remember that the UK switches to Daylight Saving Time on different dates than many countries, typically the last Sunday in March and October, so verify the current time difference before important calls.
