(WWTI) — National organizations are urging individuals to “roll up a sleeve” for World Donor Day.

World Donor Day, observed on June 14, recognizes the importance of a safe and stable blood supply and the donors who generously give to save lives.

Organizations such as the American Red Cross help promote this day by encouraging individuals to donate blood or platelets throughout the month of June.

According to the Red Cross, blood donations typically decline in late spring and early summer, especially during holiday weeks.

However, the Red Cross said that blood and platelet donors are critically important in providing lifesaving care to patients in need. Below is a breakdown of the different types of donations:
