Science has more holidays than most people realize — and each one is a chance to recognize a teacher, a lab team, a nurse, or a new graduate with something they'll actually keep. Here's a month-by-month calendar of the science holidays worth marking, with a gift guide for each. Bookmark it and you'll never be caught without an idea.

February

Periodic Table Day — February 7

Celebrate the elements with trivia and engraved gifts. See our Periodic Table Day gift guide.

April

Lab Week (Medical Laboratory Professionals Week) — mid-April

Recognize the lab techs who keep diagnostics running. See our Lab Week gift guide.

May

Nurses Week — May 6–12

Honor nurses with practical, durable gifts. See our Nurses Week gift guide.

Graduation season — May–June

Mark the milestone for new scientists and engineers. See our STEM graduation gifts guide.

October

National Chemistry Week — third full week

An ACS celebration of chemistry in everyday life. See our National Chemistry Week gift guide.

Pharmacy Week — third week

Mole Day — October 23 (6:02 a.m.–6:02 p.m.)

The chemistry world's favorite pun holiday. See our Mole Day gift guide.

The gift that works for every science holiday

Across all of these, the same principle holds: give something useful and well made rather than a novelty. Our most-gifted pieces are the Flask Vessel (an insulated Erlenmeyer flask water bottle) and the Beaker Drink Tumbler — both easy to personalize with engraving for the occasion.

Shopping for a team, class, or department?

Custom and bulk orders with engraving start at 25 units — ideal for recognizing a whole lab, floor, or science department. Or browse everything in the chemistry gifts & drinkware collection, and see our best science gifts guide for more.
