SANDY SPRINGS

Pi Day

March 14, 2015, also can also be written as 03.1415 — which numbers gurus may recognize as the value of pi. Whether you’re a math expert or not, Battle and Brew in Sandy Springs wants to bring out your inner geek with a celebration of pi’s edible homonym. The chefs there will celebrate Pi Day with a variety of pies, from chicken pot to fruit. The event also marks the reopening of the restaurant, bar and all-round gamer haven, which moved from its former location in Marietta. The new space offers patrons a choice between console and PC games and the chance to take part in regular tournaments and events.

5 p.m. March 14. No cover charge. Battle and Brew, 5920 Roswell Road, Sandy Springs. 678-560-1500, battleandbrew.com.

St. Patrick’s Day Festival

St. Patrick’s Day falls on a Tuesday this year, which for many means a work night with a lot less imbibing of green beer. But, fear not, Smyrna has you covered by starting the party early. Atkins Park Smyrna and Zucca Pizzeria will hold an all-day event the Saturday before the Irish holiday. The fun starts at noon with live music, cornhole and plenty of alcoholic refreshments. At 5:30 p.m., Smyrna Mayor Max Bacon will dye the city’s fountain green to get the evening into full swing. If you’re up for more fun, the celebration will continue on the actual St. Patrick’s Day with food and live music.

March 14. Noon-10 p.m. $10 online; $15 at the entrance gate. Smyrna Market Village, 2840 Atlanta Road, Smyrna. 770-435-1887, atkinspark.com.
