Typical customs include spending quality time with parents, giving thoughtful gifts, planning special outings, or expressing gratitude through letters or homemade cards. Activities may range from dining out together to creating personal gifts like scrapbooks or videos that highlight cherished memories. The day emphasizes the importance of parental roles in guiding and supporting children throughout their lives.
