When creating a transaction in the Generator you may want to set the transaction date several months or years in the past.
Here's the trick to do this quickly. Assume you want to select the date September 5th, 2012:
From the Add transaction screen, click the Transaction Date field to open the calendar.
The calendar box appears and defaults to the current date:
Click on the title at the top with the selected month and year (April 2021 in this example).
This will switch the date picker to the month picker:
Click the title again (2021 in this example) and the picker switches again to the year picker:
You can then navigate back through several years at once. Clicking on a year will then show the month picker, and clicking a year will allow you to select the date.
