The time has come to begin planning for 2022.
The first place to look at is the holidays. The issue here is that many of these holidays dates are based on the lunar calendar, not the solar one that we use. This caused them to move in our calendar. A few years ago, this happened to one of my clients when they ordered cards for Chinese New Year. They thought it was the same as the previous year, so they got their cards too late.
So I suggest you click here. Here there is an impressive list of holidays in Australia. If you need clarification on a holiday, click on it to get a description.
If you have many customers from other countries, you can select that country to see if they have any special holidays!
I am sure you will get some good ideas here.
