Thanks to Karen Turner from Turner Efficiency for this awesome tip:
Add that country’s holidays to your calendar.
Being culturally cognizant can help you successfully close a business deal, remember to wish someone well, and/or travel at low seasons for better fares.
You can even add non-statutory holidays (such as International Women’s Day) or sports calendars.
