It's true, St. Patrick's Day is Friday (don't miss our list of the city's best Irish bars here), but there are still all the other days of the week to fill. Here are some ideas:

TUESDAY, MARCH 14

PI DAY CELEBRATION: Today is Pi Day, a celebration of the never-ending number that begins with 3.14. That means free admission to the Exploratorium, with a full day's schedule of Pi-themed events including lectures, a procession, and (of course) pie. The Exploratorium, Pier 15, 10 a.m.-5 p.m., free.

PI PUZZLE PARTY: Dig the Pi, but prefer something a little more challenging? At Ask a Scientist's Pi Day Puzzle Party, you'll have the chance to participate in a math and logic puzzle competition solo or on a team of up to 6 people. Bring your own scratch paper and an empty stomach, as the trucks of SoMa StrEat Food will be there to slake your hunger. SoMa StrEat Food Park, 428 11th Street, 7-9:30 p.m., free but RSVPs are requested here.

WEDNESDAY, MARCH 15

VINTAGE WINE LABEL CHAT: UC Davis wine historian James Lapsley explains how CA's wine industry came to be such a force by way of 20 vintage labels from each era in its history. Included are a glass of wine and a chance to explore an exhibition of post-Prohibition era labels. California Historical Society, 678 Mission Street, 6 p.m., tickets are $10 and are available here.

NERF GUN SPY GAME: Make like a cinema badass (albeit a badass with a Nerf gun) as you chase opponents through Union Square like the full-grown adult human being you are. Bring an unmodified Nerf gun and a bandana, which will be used to signal your untimely demise. Union Square (exact location shown upon RSVP), 7 p.m., free with RSVP here.

THURSDAY, MARCH 16

FREE LIVEHUMAN SHOW: SF-based musical act LiveHuman has been described as "a real-time meeting of technolog and analog," and has been issuing records since 1997. Twenty years later, they've got yet another album, one they're supporting with this free show at Amoeba tonight. Amoeba Music, 1855 Haight Street, 6 p.m., free.

AUTHOR APPEARANCE: From Abu Dhabi by way of Chicago, professor Deepak Unnikrishnan's first novel, Temporary People, won the Restless Books Prize for New Immigrant Writing. He's reading in conversation with local writer Shanthi Sekaran, discussing "the disturbing ways in which 'progress' on a global scale is bound up with dehumanization." City Lights, 261 Columbus Avenue, 7 p.m., free.

FRIDAY, MARCH 17

IRISH MUSIC ALL DAY: In celebration of St. Patrick's Day, the Irish Cultural Center is hosting live music all day long, with a traditional Irish lunch served from 11 a.m. to 3 p.m. and dinner service starting at 4 p.m. And, oh yes, there is a full bar. United Irish Cultural Center of San Francisco, 2700 45th Avenue, 11 a.m. to at least 8 p.m., music is free but the food and drinks you'll pay for.

NOIR MUSIC EVENT: Too cool to wear green? How about black? In this week's installment of the Presidio Sessions, you get to hear composer and musician Lisa Mezzacappa's avantNOIR, a "suite of compositions inspired by noir genre fiction." Mezzacappa herself will be on the bass, joined by a quartet of musicians making her work come alive. Presidio Officers' Club, 50 Moraga Avenue, 6-7:30 p.m., free with registration.

SATURDAY, MARCH 18

CODE-BASED ART SHOW: Described as "a first-of-its-kind Bay Area event," 'Luminary: Art, Tech, Music' features the work of creators and musicians using emerging technologies like drones, VR, and projection mapping. The Midway, 900 Marin Street, 7 p.m.-2 a.m., tickets are $25 - $85 and are available here.

ARBOR DAY CELEBRATION: Observe Arbor Day with San Francisco Public Works' Eco Fair, which promises face painting, goats to pet, activities, and education on the environment. You had me at "goat." Warm Water Cove Park, 24th and Michigan Streets, 9 a.m.-12 p.m., free.

SUNDAY, MARCH 19

AVOCADO CON: "15 of the best local street food vendors are gathering for the Bay Area’s first avocado food festival," we're told via press release (which did NOT arrive with any examples to taste, to my dismay). There will be avo shakes, deep fried creations, guacs galore, and even avo desserts that I am a little bit skeptical of about but could be convinced. SPARK Social SF, 601 Mission Bay Boulevard North, 11 a.m.-5 p.m., admission is $5 and is available here.

FREE CERAMICS STUDIO TIME: Ever picked up some handcrafted $300 bud vase and thought "I'll bet I can do that"? Well, here's your chance to put your mud where your mouth is, with an all-ages day of free ceramics hand building at Sharon Art Studio in Golden Gate Park. Kids under 10 need a parent with them, but grownups like us need not reciprocate by bringing a child. The Glass Studio at Sharon Art Studio, 300 Bowling Green Drive (Golden Gate Park), 11 a.m.-3 p.m., free.

MONDAY, MARCH 20

SPRING EQUINOX CEREMONY: Observe today's spring equinox at San Francisco's storied Zen Center, where "words of the season are offered" in a (outdoors in their courtyard, weather permitting) ceremony immediately following morning zazen, at the time of morning service. San Francisco Zen Center, 300 Page Street, 6:30 a.m., free.

DIEGO RIVERA TOUR: The first mural Diego Rivera ever painted in the US, “Allegory of California," is typically not available for the public to view (talk about your allegory of SF, huh?). Occasionally, SF City Guides gets access to this work, located in the stairwell of SF's City Club (née the Pacific Stock Exchange Lunch Club) a building that's "considered the best interior in the Art Deco style in San Francisco, and among the best in California." This is one of those times, as 25 lucky registrants will get behind the velvet rope and in front of the Rivera. Exact meeting location with reservation (make it here), 3 p.m., free.
