Since there are 7 days in a week, the day will repeat again after 7 days.  Thus, if today is Monday, it will be Monday again a week later.  $$22\div 7=3$$ week R $$1$$.  The day after $$22$$ days is the same as the day after $$1$$ day.  $$1$$ day after Monday is Tuesday.  Therefore, it will be \textbf{Tuesday} $$22$$ days later.
