Unhyeongung’s May constellation observation program is scheduled for Friday, May 29, 2026, under the official title “Counting Stars at Unhyeongung.” The evening program runs from 18:30 to 21:00 around Unhyeongung and is part of Seoul’s May “Seoul Culture Night” programming, with urban stargazing, moonlit cultural commentary, and a picnic-mat tea time listed as key activities. 1
For readers searching for Unhyeongung Stargazing in May, the most important point is that this is a small, advance-registration night program rather than a walk-in festival. Seoul’s detailed night-program guide lists the 2026 “Counting Stars at Unhyeongung” dates as April 17, May 29, and November 13, each held once, with the May session now the next source-backed date after the April session. 2
Unhyeongung May Stargazing: Date, Time, and Place

The May event is set for Friday, May 29, 2026, from 18:30 to 21:00. The announced venue is the Unhyeongung area, and the broader 2026 operation plan identifies the specific spaces as the Unhyeongung front yard, Irodang, and Norakdang. 1 2
That venue detail matters because the program is not simply a telescope session in one fixed spot. The April 2026 program page described the session structure as a moonlit walk through Unhyeongung, a picnic-mat tea time, and a constellation class. 3 The May notice uses slightly different wording, listing city-center stargazing, moonlit cultural interpretation, and picnic-mat tea time, but the overall visitor experience is clearly built around both the palace setting and the night-sky component. 1
Because the program is held in the evening, readers should plan around the full 18:30 to 21:00 time block. The source material does not provide a detailed minute-by-minute May itinerary, so it is safest to treat the published time as the required participation window rather than assuming late arrival will be possible.
Booking, Capacity, and Fee Details
The 2026 Unhyeongung night-program guide states that “Counting Stars at Unhyeongung” operates by advance registration for teams of two, with 30 participants per session and a participation fee of 15,000 won per person. 2 In practical terms, that means each session is built for 15 two-person teams, matching the small-group format used in past May programming.
For the May 29 session, Seoul’s May program notice tells readers to check advance guidance on the Unhyeongung website for application details. 1 The official Unhyeongung post for the April 17, 2026 session identified that event as an advance-registration program and included a Naver Reservation link; it also listed the Unhyeongung Management Office phone number as 02-766-9090. 4 The source material does not provide a separate May 29 reservation URL, so readers should rely on the Unhyeongung website’s program notices and the listed management office contact if they need confirmation.
The April 17 session is already in the past relative to April 30, 2026, but it helps clarify how the 2026 series is structured. The next date supported by the supplied official schedule is May 29, followed by November 13. 2 Anyone planning around the May date should avoid using last year’s May details as current booking information, even though the 2025 May session shows the same general pattern of a Friday evening program at Unhyeongung with tea time and night-sky observation. 5
What to Expect on the Night
The source-backed program elements point to a quiet, structured cultural evening rather than a large open public event. Visitors can expect a mix of palace-at-night interpretation, tea time in the Unhyeongung setting, and a constellation-focused activity. 1 3
The stargazing component is weather-sensitive. The April 2026 program page stated that star observation could be reduced or replaced by an indoor experience depending on weather conditions. 3 That notice is attached to the April session, but because it describes the same 2026 “Counting Stars at Unhyeongung” program format, it is a relevant planning caution for the May session as well. Readers should not assume telescope or sky-viewing activity will proceed unchanged if the weather is poor.
The program also has precedent as a recurring Unhyeongung night event. A 2024 News1 report carried by Financial News noted that Seoul prepared 31 major events across Namsangol Hanok Village and Unhyeongung that year, including “Counting Stars at Unhyeongung” on Friday evenings in April, May, and November using star-observation equipment at Norakdang. 6 That earlier report is not the booking source for 2026, but it reinforces that the program has been organized as a seasonal evening experience at Unhyeongung.
