In 2023, Mercury will be in apparent retrograde motion during the following ranges of dates:
December 28, 2022, to January 18, 2023
April 21 to May 14
August 23 to September 14
December 13 to January 1, 2024
An older video but still does the trick on teaching a clear communication spell created to help you through those difficult retrogrades!
Again, an older video - since it has 2022 dates but all the information can still be applied except note the dates listed above for 2023.
