How to convert time from India Standard Time (IST) to Japan Standard Time (JST)

Converting between India Standard Time (IST) and Japan Standard Time (JST) could be challenging. As companies become more global, we find ourselves in a mess of calendar invites. Time changes from IST cities like New Delhi, Mumbai, Kolkata, Bangalore, Chennai are 4 hour(s) apart to JST cities like Tokyo, Osaka, Nagoya, Sapporo, 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 IST and JST into step-by-step instructions.

Step 1: Understanding India Standard Time and Japan Standard Time

India Standard Time is UTC5, which means that the local time in the India Standard Time zone is 5 hours apart from UTC. Japan Standard Time is UTC9, which means that the local time in the Japan Standard Time zone is 9 hours apart from UTC.

Step 2: Calculate the Time Difference

To convert time from India Standard Time to Japan Standard Time, we first need to find the time difference between both time zones. Since India Standard Time is UTC5 and Japan Standard Time is UTC9, the time difference is: 4 hour(s)

  • 4 hours = India Standard Time's difference from UTC 9 + (Japan Standard Time's difference from UTC 5
  • Japan Standard Time has 4 hour(s) difference India Standard Time.

Understanding India Standard Time and Japan Standard Time

Scheduling a meeting between India Standard Time and Japan Standard Time

When scheduling a meeting between employees in the India Standard Time and Japan 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, Japan Standard Time is 4 ahead of India Standard 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 India Standard Time but 4 hours different to Japan Standard Time. Be upfront with Japan Standard Time employees to find the right time.
  • Consideration of Local Holidays: Be mindful of local India Standard Time and Japan 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 India Standard Time and Japan Standard Time zones to avoid scheduling conflicts.
  • Communicate Time Zone Differences: Clearly communicate the meeting time in both India Standard Time and Japan 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.
