Operation Green Light Veterans 2026: Buildings Go Green Nov. 4-11

Operation Green Light for Veterans runs Nov. 4-11, 2026, Wednesday to Wednesday, according to the National Association of Counties (NACo). The group’s program page describes the campaign as “lighting our buildings green from November 4-11, 2026,” and the window covers eight calendar days counting both ends. NACo had no 2026 list of participating counties on that page as of Nov. 8, so no county is named as taking part below.

Days left in the Operation Green Light window

The clock needs JavaScript. The first option counts to midnight on your own device; the Eastern Time options count from a fixed instant. On Nov. 11, 2026, clocks are on standard time, so Eastern Time is five hours behind Coordinated Universal Time (UTC).

Operation Green Light 2026 dates by weekday

Date	Day	What happens	Days from today
Nov. 4	Wednesday	NACo’s window for lighting buildings green begins	Live
Nov. 11	Wednesday	Last day of NACo’s window	Live
Nov. 18	Wednesday	Loudoun County, Virginia, says its buildings are lit through this date	Live

The Nov. 18 row comes from Loudoun County’s notice of Nov. 2, 2026, which says buildings “will be illuminated in green light November 4 -18, 2026.” That is a week longer than the national window. NACo’s dates are Nov. 4-11, and nothing here says whether Loudoun’s end date is a local choice or a typo.

What green stands for in the campaign

NACo’s page says “Green is commonly seen as a symbol of hope, renewal and well-being.” The page does not link the color to a particular holiday in those words. For the day itself, see our Veterans Day 2026 guide and the Veterans Day parades by city.

How counties and residents take part

Counties report their participation to NACo through a “Share your participation” form, which takes photos of lit buildings, proclamations, social posts and event information. For residents, the only idea with a source is last year’s: in an Oct. 21, 2025 bulletin, Kent County, Michigan, wrote that “From November 4 - 11, residents and local businesses are encouraged to swap out their outdoor lights for green bulbs.” No 2026 resident guidance was verified.

Which counties are taking part in 2026?

Not confirmed. When the program page was captured on Nov. 8, NACo’s county map had not loaded and the page said “No activities have been shared yet.” New Castle County’s release cites more than 450 participants, but that figure refers to 2023 and 2024, so it is not a 2026 count. Check a county’s own website or social pages before planning a visit. A veteran who wants proof of status for local discounts can read our veteran ID card guide.

How Operation Green Light worked in 2025

Last year’s pattern, not this year’s: NACo’s “Highlights from 2025 Operation Green Light for Veterans,” dated Nov. 4, 2025, said “County buildings and landmarks light up in green November 4-11.” The 2026 window repeats those dates.
