Checking upcoming public holidays in Hong Kong, India etc, canceling meetings where key participants are in a location that is on holiday.
On Wednesday, Chinese National Day, which is a public holiday in Hing Ko.g as well as the Mainland.
Wednesday in two weeks, Mahatma Gandhi's Birthday, which is a public holiday in India.
I try to concentrate my meetings to Wednesdays, so those are the two relevant holidays until Christmas.
