Here are our weekend picks to keep on your radar:

Starting Friday, Dec. 4 through Thursday, Dec. 31, our fishy friends over at the Adventure Aquarium (1 Riverside Dr., Camden) hosts a month-long Christmas Celebration including seasonal scuba diving, holiday photo ops and more.

For seasonal design at its finest: On Saturday, Dec. 5 the Chestnut Hill Community Association brings back its yearly holiday tradition with a morning of decorated house tours featuring the area's historic homes, cottages and more. Things get started at 10 a.m.

Get some early holiday cheer during a Christmas Festival at Peddler's Village (Route 202 & Route 263) on Saturday, Dec. 5 and Sunday, Dec. 6 that features a weekend full of seasonal treats, a visit by Santa Claus and a parade. Things get started both days at 10 a.m.

If you haven't started your holiday shopping yet now's the time. Boutiques located in Northern Liberties will offer great sales on their specialty products on Saturday, Dec. 5 through Sunday, Dec. 6.

Picks from the Inquirer's Michael Harrington

OK, Rockefeller Center has a tree and skating, but let's see New York top this! The Blue Cross RiverRink Winterfest Tree Lighting will turn on the 40,000-bulb Christmas tree with plenty of extras. On tap are the 2015 U.S. Adult Figure Skating dance champions Shay Sterlace and Yovanny Durango, the Philadelphia Symmetry synchronized skating team, Drexel Hill's 12-year-old opera sensation (and America's Got Talent alum) Arielle Baril, the String Theory High School Chamber Strings, the Keystone State Boychoir and Pennsylvania Girlchoir, the In The Mix A Capella Group, gospel and soul singer Eric Gambre'll, 76ers power forward Robert Covington, the second-best mascot in Philly (after the Phanatic, of course) Rinky the Penguin, and someone who looks a lot like Marilyn Monroe singing "Santa Baby" to someone who looks a lot like Kris Kringle. And not to mention: a fully-functioning PNC Bank branch made of actual gingerbread. Our pal Molly Eichel went last year — she says "It's super fun." It's at the RiverRink (101 S. Columbus Blvd.) from 6 p.m. to 9 p.m. on Friday, Dec. 4.

Virtuoso lutenist Hopkinson Smith plays Elizabethan works by John Dowland, Anthony Holborne, Robert Johnson, and William Byrd at the American Philosophical Society (427 Chestnut St.) at 8 p.m. on Friday, Dec. 4.

Yannick Nézet-Séguin conducts the Philadelphia Orchestra in Stravinsky's great ballet “The Firebird,” Henri Vieuxtemps' Violin Concerto No. 4 with the luminous Hilary Hahn as soloist, and Bizet's Suite No. 1 from "Carmen." The program goes on at the Kimmel Center's Verizon Hall (Broad and Spruce Streets) at 2 p.m. Friday, Dec. 4 and 8 p.m. Saturday, Dec. 5. 

The eight days of Hanukkah begin at sunset on Sunday, and we all know what that means. Yes, the lighting of the menorah. Yes, the Maccabees tossing out the oppressing army. Yes, the story of the drops of oil that miraculously gave light for over a week. But also: Latkepalooza! The 13th edition of the potato pancake event has latkes prepared in gourmet versions by nine of Philadelphia's top chefs (including traditional and gluten-free), plus music, crafts, and balloon animals. It's at the Gershman Y (401 S. Broad St.) at 2 p.m. on Sunday, Dec. 6.
