For the larger, one-day events, (basically happening monthly) I like the idea of having a similar event flier design with slightly different features based on the neighborhood, time of year, etc.
Free Printable 2015 Calendar offered from Lemon Thistle. Design, inspired - love these for an at a glance or a great dinner planner for the month.
.:* L - Love these Pantone Wall Calendars!! [found by Design Vagabond: "This calendar by Jonathan Davies captures the essence of each month through a gradient of color. A beautiful item to display even after the year is over."]
