I love my dad wish happy fathers day to your father. Father's day complements similar celebrations honoring family members, such as Mother's Day, Siblings Day and Grandparents' Day. This year spending time outside home may not be the best thing to do because of the COVID-19 pandemic but there are a number of things you can do indoors with your dad. So start the planning now! Father's Day is celebrated in many parts of the world at different times of the year, mostly in March, May and June.
