GMT to AST Converter

Use our converter below to change times between Greenwich Mean Time (GMT) to Arabian Standard Time (AST). If you mixed up your time zones and would like to convert AST to GMT instead, you can find that converter here: Arabian Standard Time to Greenwich Mean Time Converter. And if you don't like either of our tools, then go back to see all of our time zone converters.

Greenwich Mean Time

Greenwich Mean Time (GMT) is the time zone used as the basis for calculating time differences worldwide. It is the same as Coordinated Universal Time (UTC) and has no associated cities, as it serves as a reference point for all other time zones.

Cities:

Arabian Standard Time

Arabian Standard Time (AST) is the time zone used in some countries in the Middle East, including Saudi Arabia, where cities like Riyadh and Jeddah are located. It is 3 hours ahead of UTC and does not observe daylight saving time.

Cities:

  • Riyadh
  • Jeddah
  • Mecca
  • Medina

How to convert time from Greenwich Mean Time (GMT) to Arabian Standard Time (AST)

Converting between Greenwich Mean Time (GMT) and Arabian Standard Time (AST) could be challenging. As companies become more global, we find ourselves in a mess of calendar invites. Time changes from GMT cities like are 3 hour(s) apart to AST cities like Riyadh, Jeddah, Mecca, Medina, 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 GMT and AST into step-by-step instructions.

Step 1: Understanding Greenwich Mean Time and Arabian Standard Time

Greenwich Mean Time is UTC0, which means that the local time in the Greenwich Mean Time zone is 0 hours apart from UTC. Arabian Standard Time is UTC3, which means that the local time in the Arabian Standard Time zone is 3 hours apart from UTC.

Step 2: Calculate the Time Difference

To convert time from Greenwich Mean Time to Arabian Standard Time, we first need to find the time difference between both time zones. Since Greenwich Mean Time is UTC0 and Arabian Standard Time is UTC3, the time difference is: 3 hour(s)

  • 3 hours = Greenwich Mean Time's difference from UTC 3 + (Arabian Standard Time's difference from UTC 0
  • Arabian Standard Time has 3 hour(s) difference Greenwich Mean Time.

Understanding Greenwich Mean Time and Arabian Standard Time

Greenwich Mean Time is UTC0, which means that the local time in the Greenwich Mean Time zone is 0 hours apart from UTC. Arabian Standard Time is UTC3, which means that the local time in the Arabian Standard Time zone is 3 hours apart from UTC.

Step 4: Practice Converting Times

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

Scheduling a meeting between Greenwich Mean Time and Arabian Standard Time

When scheduling a meeting between employees in the Greenwich Mean Time and Arabian Standard 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, Arabian Standard Time is 3 ahead of Greenwich Mean 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 Greenwich Mean Time but 3 hours different to Arabian Standard Time. Be upfront with Arabian Standard Time employees to find the right time.
  • Consideration of Local Holidays: Be mindful of local Greenwich Mean Time and Arabian Standard Time holidays, festivals, or observances in both time zones. These events might affect employee availability or working hours. Check local calendars for both the Greenwich Mean Time and Arabian Standard Time zones to avoid scheduling conflicts.
  • Communicate Time Zone Differences: Clearly communicate the meeting time in both Greenwich Mean Time and Arabian Standard 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.
