Celebrate health and medicine during National Chemistry Week, Oct. 15-21

News Releases


WASHINGTON, Oct. 5, 2023 — The American Chemical Society (ACS) invites everyone to join it in celebration of chemistry’s biggest “holiday,” National Chemistry Week (NCW), from Sunday, Oct. 15, to Saturday, Oct. 21. This is an opportunity to spotlight chemistry with a focus on this year’s theme, “The Healing Power of Chemistry.”

NCW builds awareness of the positive impacts of chemistry at the local, national and global levels. The observance began as National Chemistry Day on Nov. 6, 1987, but soon evolved into a weeklong event, which takes place annually during the third week of October.
