To calculate the number of weeks since your last seen period on December 27th, 2018, you can use a simple formula. First, determine the current date. Then, subtract the date of your last seen period from it. Finally, divide the result by 7 to get the number of weeks. For example, if today is February 15th, 2022, and your last seen period was on December 27th, 2018:

Current Date: February 15th, 2022

Last Seen Period: December 27th, 2018

Calculation:

February 15th, 2022 - December 27th, 2018 = approximately 1 year and almost two months (around 414 days).

Approximately 414 days /7 = around59 weeks.

Therefore, if today is February 15th,2022 and your last seen period was on December27th ,2018 ,you are approximately59weeks along since your last seen period.
