Right now, if you drop off a bag of old costumes or coats somewhere downtown, you're part of the Chamber's Clothing and Costume Donation Drive, which opened its collection window today and runs through October 4. It's a small, practical detail, the kind of thing that only shows up on a town calendar you actually check. But it also marks the start of a six-week stretch that Mill Valley residents have been trained, by years of habit, to read in the wrong order.

For as long as most people here can remember, the Mill Valley Fall Arts Festival has been the town's unofficial closing bell. Two days under the redwoods at Old Mill Park, art booths, live music, the sense that summer is packing up. This year's festival, the 69th, ran September 19 and 20, drawing 135 juried artists into the park the way it has since a handful of painters first hung their work in downtown store windows back in 1957. If you went, you already know the season felt finished when you walked out.

Except it isn't. Concerts in the Plaza, the free outdoor concert series that has historically run before or alongside the Fall Arts Festival, lands this year on September 26, a full week after the festival closed. That's not a minor scheduling quirk. It's a genuine reversal of the order residents have relied on to know when the outdoor calendar wraps up.

The Concert That Used to Come First

Look back at how the series has run in past years and the pattern is consistent: a two-day event in the first two weeks of September, sometimes September 7 and 8, other years September 9 and 10, always positioned ahead of or overlapping with the Fall Arts Festival rather than after it. That timing made sense. Concerts in the Plaza read as the last hurrah of summer, the warm-up act before the bigger, more formal art weekend closed things out.

This year the Mill Valley Arts Commission moved it. Concerts in the Plaza now runs a single day, September 26, from 11:00 a.m. to 7:30 p.m. at the Downtown Plaza on Throckmorton Avenue. The lineup opens with Give Me a Dollar, a musical project led by Tommy Freiburger and Karsen Scott, and continues through the afternoon with acts spanning Americana, folk, blues, rock, and power pop. Bring a chair, grab food from a downtown restaurant, and settle in.

The shift from two days to one, and from early September to late September, means the event now functions less like summer's last gasp and more like fall's opening number. If you used the Fall Arts Festival as your internal signal that the free outdoor season was over, you'd have walked right past this one.

Six Weeks, Five Events, One Pattern

Here's what the stretch from today through mid-October actually looks like when you lay it out:

Read across that table and the pattern is that nothing here is a repeat of what just happened at Old Mill Park. Each event pulls a different slice of the town out of the house: the civic-minded crowd shows up for the mayor's Sunday conversation about current issues facing the town, families and dog owners turn out for the animal blessing, and the shopping crowd gets pulled toward Miller Avenue for the Lumber Yard's next artisan fair, which the organizers are explicitly framing as the start of Halloween season and early holiday shopping rather than a summer leftover.

Why October 4 Isn't a Random Date

The Blessing of the Animals falling on October 4 isn't a scheduling coincidence. It's the feast day of St. Francis of Assisi, the patron saint most commonly associated with animals, and churches that hold pet blessings almost always anchor them to that date. Mt. Tam Church's version runs from noon to 12:45 p.m., a short window, so if you're bringing a dog, cat, or anything else that travels well on a leash or in a carrier, plan to arrive close to the start.

What's worth noticing is that this same church hosts both the mayor's meet and greet on September 27 and the animal blessing a week later. Two very different kinds of gatherings, one civic and one seasonal, sharing the same address within seven days of each other. It's a small sign of how much of Mill Valley's fall social calendar runs through a handful of repeat venues rather than spreading thin across the town.

The Dog Contest Got Harder to Enter

Further out, the Mill Valley Lumber Yard is preparing its fourth annual Howl-O-Ween Dog Costume Contest. The Lumber Yard hasn't posted an exact date yet, but the last three years give a reliable window: the third annual contest ran October 26, 2025, and the event before that landed in the same late-October stretch. Expect this year's contest to fall in the last week of the month again.

One detail is worth flagging for anyone who wants to actually enter a dog. In past years, the contest capped registration at the first 100 dogs to show up. This year's early listing caps it at 70. That's not a huge number on its own, but it's a meaningful drop, and it suggests the event has outgrown its original format enough that organizers are tightening the gate rather than trying to accommodate everyone who wants in. If Howl-O-Ween is on your list this year, don't plan to stroll up at showtime.

What This Means If You Live Here

The practical takeaway isn't complicated, but it does require unlearning a habit. The Fall Arts Festival used to be the moment you could mentally file the outdoor season as finished. This year, five more dated, named events follow it inside of three weeks, and at least two of them, Concerts in the Plaza and the Makers Market, are explicitly framed by their own organizers as fall programming rather than summer carryover.

If you're the kind of resident who plans weekends around what's actually on the plaza and not what you remember being on it last year, the move is simple: put September 26, September 27, October 4, and October 10 on the calendar now, and watch the Lumber Yard's site for the Howl-O-Ween date once it posts. The town isn't winding down. It rearranged the order and kept going.

A Note from Tam Home Team

We put pieces like this together because we live and work in this town, and the calendar tells you as much about a place as any listing does. If you're already searching for how Mill Valley works, from its event order to its neighborhoods to what a home here actually costs to live in day to day, that curiosity tends to lead somewhere. When it does, Tam Home Team is here for a conversation, whenever you're ready for one.
