Yom Hazikaron (Hebrew: יום הזיכרון לחללי מערכות ישראל ולנפגעי פעולות האיבה‎, lit. Israeli Fallen Soldiers and Victims of Terrorism Remembrance Day) is Israel's official Memorial Day. In 2011, Israel honored the memory of soldiers killed in the line of duty and the civilian casualties too.

Yom Hazikaron is the day on which Israel honors its fallen servicemen and women. National memorial services are held in the presence of Israel's top leadership and military personnel. The day opens with a siren the preceding evening at 20:00 (8:00 pm), given that in the Hebrew calendar system, the day begins at sunset. The siren is heard all over the country and lasts for one minute, during which Israelis stop everything (including driving, which stops highways) and stand in silence, commemorating the fallen and showing respect. Many religious Jews say prayers for the souls of the fallen soldiers at this time. The official ceremony to mark the opening of the day takes place at the Western Wall, and the flag of Israel is lowered to half staff.

Administrative Professionals' Day (also known as Secretaries Day or Admin Day ) is an unofficial secular holiday observed in several countries to recognize the work of secretaries, administrative assistants, receptionists, and other administrative support professionals. In North America, it is celebrated on the Wednesday of the last full week of April (April 25 in 2012). In much of Europe it is celebrated on the third Thursday in April^[1] (April 19 in 2012).

The idea began with Mary Barrett, president of the National Secretaries Association, now called IAAP (International Association of Administrative Professionals), and C. King Woodbridge, president of Dictaphone Corporation. They served on a council addressing a national shortage of skilled office workers. Together with Harry Klemfuss, public relations account executive at Young & Rubicam, they originated the idea for a National Secretaries Week.

Children's Day is celebrated on various days in many places around the world, in particular to honor children. Major global variants include a Universal Children's Day on November 20, by United Nations recommendation.^[1] Children's Day is often celebrated on other days as well.

The World Conference for the Well-being of Children in Geneva, Switzerland proclaimed June 1 to be International Children's Day in 1925. It is usually marked with speeches on children's rights and wellbeing, children TV programs, parties, various actions involving or dedicated to children, families going out, etc.^[2][3] Official discourse in Turkey argues that Children's Day had its origin in Turkey. The Grand National Assembly of Turkey was established on 1920, April 23, and to commemorate the event, April 23 was proclaimed a national holiday in 1921. The founder of The Republic of Turkey,Atatürk, has given this day to the children.
