How to convert time from Brasília Time (BRT) to British Time (BT)

Converting between Brasília Time (BRT) and British Time (BT) could be challenging. As companies become more global, we find ourselves in a mess of calendar invites. Time changes from BRT cities like São Paulo, Rio de Janeiro, Belo Horizonte, Brasília are 5 hour(s) apart to BT cities like London, Birmingham, Manchester, Glasgow, holiday schedules, and the basic communication becomes a juggling act. To make it easier to understand, we'll break down the process of converting time between BRT and BT into step-by-step instructions.

Understanding Brasília Time and British Time

Brasília Time is UTC-3, which means that the local time in the Brasília Time zone is -3 hours apart from UTC. British Time is UTC1, which means that the local time in the British Time zone is 1 hours apart from UTC.

Calculate the Time Difference

To convert time from Brasília Time to British Time, we first need to find the time difference between both time zones. Since Brasília Time is UTC-3 and British Time is UTC1, the time difference is: 5 hour(s)

  • 5 hours = Brasília Time's difference from UTC 1 + (British Time's difference from UTC -3
  • British Time has 5 hour(s) difference Brasília Time.

Step 3: Add the Time Difference to the Brasília Time Time

To convert a specific time from Brasília Time to British Time, we simply add the time difference (5 hours) to the Brasília Time time. Make sure to also adjust the day if the converted time goes past midnight. Or if you are using 24-hour time or Military Time, ensure you’re using the correct attributes.

Step 4: Practice Converting Times

Now that you know the process, try converting different times from Brasília Time to British Time for practice before going to the answer page. Remember to always add the British Time time difference to the Brasília Time time.

Scheduling a meeting between Brasília Time and British Time

When scheduling a meeting between employees in the Brasília Time and British Time zones, there are several factors to consider to ensure that the meeting is convenient and productive for all participants. Here's a detailed breakdown of what you should consider before scheduling across time zones:

  • Convert Time Difference: As we've discussed earlier, British Time is 5 ahead of Brasília Time. It's crucial to take this time difference into account when scheduling a meeting to avoid scheduling conflicts or creating meetings at odd or inappropriate hours. In my experience, accidentally scheduling a meeting a 4am is awkward.
  • Overlapping Working Hours: To find a suitable time for the meeting, you’ll need to identify the overlapping working hours between the two time zones. For example, if employees in both zones work from 9:00 AM to 5:00 PM local time, the overlapping hours could be between 9:00 AM and 11:00 AM Brasília Time but 5 hours different to British Time. Be upfront with British Time employees to find the right time.
  • Consideration of Local Holidays: Be mindful of local Brasília Time and British Time holidays, festivals, or observances in both time zones. These events might affect employee availability or working hours. Check local calendars for both the Brasília Time and British Time zones to avoid scheduling conflicts.
  • Communicate Time Zone Differences: Clearly communicate the meeting time in both Brasília Time and British Time to avoid confusion. Using a tool like an online meeting planner or time zone converter can help simplify the process and ensure accuracy.

Converting time zones across other countries

The process of converting time between two time zones is similar regardless of the countries involved. You'll need to determine the time difference between the two zones and add it to the time in the first zone. Keep in mind that some countries may observe daylight saving time or have different time zones within the country. It's important to double-check the time difference before scheduling any meetings or events.
