A romantic holiday other than Valentine's Day, I think is Christmas. Also New Years' Day is very romantic because you make so many new dreams together as a couple.
Any holiday will be as romantic as you make it. Sweetest day is another hallmark holiday. New Years can be a very romantic holiday. Christmas is quite romantic also I think.
some romantic holidays can be your birthday, valentines day and christmas. Another romantic holiday can be new years eve and mothers or father day as well.
