No, daylight saving time does not affect this conversion. KST remains constant throughout the year, while GMT does not change with daylight saving time. Therefore, when converting from KST to GMT, you consistently subtract 9 hours.

Can I convert multiple times from KST to GMT at once?

What should I consider when scheduling meetings across KST and GMT?

When planning meetings between participants in KST and GMT, be mindful of the 9-hour difference.

This ensures that all parties can attend without conflicts.
