The Genshin Impact Version 5.1 Special Program was scheduled for September 27, 2024, at 8:00 a.m. UTC−4 (12:00 UTC). That broadcast is now historical, so a countdown to its start has expired. The official Genshin Impact YouTube channel published the program video on September 27, 2024.
The livestream and the game update happened on different dates. Version 5.1 maintenance was scheduled to begin on October 9, 2024, at 6:00 a.m. UTC+8, with an estimated five-hour duration. The schedule below separates the presentation from the playable update so you do not mistake one for the other.
When was the Genshin Impact 5.1 livestream?
HoYoverse announced the Version 5.1 Special Program for Friday, September 27, 2024, at 8:00 a.m. UTC−4. In Coordinated Universal Time, that is 12:00 UTC. The schedule appeared in the official HoYoLAB announcement posted on September 26, 2024.
Because the event took place in 2024, it is not an upcoming broadcast. Any page still showing a live countdown to that start time is displaying an expired timer rather than a current Genshin event.
Schedule at a glance
| Event | Official date and time | What that means now |
|---|---|---|
| Version 5.1 Special Program | September 27, 2024, 8:00 a.m. UTC−4 (12:00 UTC) | Past event; countdown expired |
| Official YouTube publication | September 27, 2024 | Replay is available from the verified Genshin Impact channel |
| Version 5.1 maintenance start | October 9, 2024, 6:00 a.m. UTC+8 | Separate update event, estimated at five hours |
The first two rows describe the presentation itself. The last row comes from HoYoverse’s separate Version 5.1 update notice; it is not the livestream start time.
What time did the 5.1 Special Program start in UTC?
The announced start was 12:00 UTC. The original notice used the UTC−4 offset, so readers should keep the offset attached to the local time rather than treating “8:00 a.m.” as a universal time. A location using another offset could see a different clock time or even a different calendar date.
How to convert the announced time
- Start with the published local offset: 8:00 a.m. at UTC−4.
- Add four hours to reach UTC: 12:00 UTC.
- Convert 12:00 UTC to your own location using the offset in effect on September 27, 2024.
For example, a viewer in a location observing UTC itself would use noon. A viewer west of UTC could see the event in the morning, while a viewer far east of UTC could see it after midnight on September 28. The date change is a normal time-zone conversion, not a second airing.
Where could viewers watch the Genshin 5.1 livestream?
The announcement named the official Genshin Impact channels on Twitch and YouTube. It reported that the YouTube post would follow the Twitch premiere by one hour. That one-hour difference is information from the announcement; the official video description does not independently document the platform delay.
The verified YouTube upload is available as Genshin Impact Version 5.1 Special Program. Its publication date is September 27, 2024, matching the announced program date. Since no Twitch URL is supplied with the schedule, use the official announcement and verified channel pages rather than guessing at an old stream address.
How to verify that a replay is official
- Check that the uploader is the verified Genshin Impact YouTube channel.
- Confirm that the video title identifies it as the Version 5.1 Special Program.
- Check the publication date, which is September 27, 2024.
- Use the original announcement for the planned time and platform order, rather than relying only on a repost’s timestamp.
Is the 5.1 livestream countdown still running?
No. As of October 8, 2026 UTC, the September 27, 2024 start time has passed by more than two years. A correct countdown for this exact event should show an expired or completed state, not days, hours, or minutes remaining.
The practical replacement for a live timer is the official replay. If you are building or checking a fan countdown page, preserve the original event date and offset, mark the event as completed after the target time, and provide the archived video. Resetting the timer to a later date would describe a different program and would mislead readers.
Why an old countdown may show the wrong result
- Device clock: A computer or phone with an incorrect date can calculate a misleading remaining time.
- Time-zone handling: Treating UTC−4 as UTC, or converting it twice, shifts the target by four hours.
- Platform assumptions: A timer aimed at the Twitch premiere should not be labeled as the YouTube availability time when the announcement reported a one-hour difference.
- Stale scripts: A page that never switches from “upcoming” to “ended” can continue displaying a negative or nonsensical value.
When did Genshin Impact Version 5.1 come out?
The playable update had a separate maintenance schedule. HoYoverse’s official update details said maintenance would begin on October 9, 2024, at 6:00 a.m. UTC+8, and estimated that maintenance would take five hours. In UTC, that start corresponds to 22:00 on October 8, 2024.
This distinction matters when reading old guides or calendar entries:
| Question | Correct event | Published schedule |
|---|---|---|
| When was the preview broadcast? | Version 5.1 Special Program | September 27, 2024, 8:00 a.m. UTC−4 (12:00 UTC) |
| When did update maintenance begin? | Version 5.1 game update maintenance | October 9, 2024, 6:00 a.m. UTC+8; estimated five hours |
The livestream was a presentation about the update. Maintenance was the service window used to deploy it. Neither date should be substituted for the other in a countdown, calendar reminder, or article headline.
What did the official program description promise?
The verified Genshin Impact channel described the broadcast this way: “This special program will feature juicy details about new game content and developments in Version 5.1.” That sentence is the official description of the program’s purpose and is reproduced on the official video page.
The schedule sources do not provide a verified attendance figure, viewership total, or other named statistic for the broadcast. They also do not establish a separate product, purchase, or physical item needed to watch it. For a date-and-time question, the reliable information is the announced schedule, the official archive, and the later maintenance notice.
What is the complete Version 5.1 timeline?
- September 26, 2024: HoYoLAB posted the Special Program announcement with the planned date, time, and official Twitch and YouTube destinations.
- September 27, 2024: The Special Program was scheduled for 8:00 a.m. UTC−4, equal to 12:00 UTC. The official YouTube channel published the program video that day.
- October 8, 2024 at 22:00 UTC: The announced October 9 maintenance start in UTC+8 falls on the previous UTC calendar date.
- October 9, 2024: Version 5.1 maintenance was scheduled to begin at 6:00 a.m. UTC+8, with an estimated five-hour duration.
This sequence explains why a search result can show September 27 for the broadcast and October 9 for the update without either date being an error.
How should readers use this information now?
If you want to watch the presentation
Open the official YouTube replay and compare its September 27 publication date with the announcement. This is the appropriate source for reviewing what was said after the live broadcast has ended.
If you are checking an old event calendar
Record the program as a completed event at 12:00 UTC on September 27, 2024. Do not move the date forward simply because a countdown widget still appears on an archived page.
If you are researching the update release
Use the maintenance notice, not the livestream announcement. Its stated start is October 9, 2024, at 6:00 a.m. UTC+8, with a five-hour estimate; maintenance timing is a separate operational schedule from the preview broadcast.
Frequently asked questions
Why does my calendar show September 26 instead of September 27?
The published time is tied to UTC−4. Converting 12:00 UTC into a location west of UTC can move the local date to the previous evening, while locations east of UTC may see September 27 or September 28 depending on their offset. Always save the UTC value alongside the local time when comparing calendars.
Did Twitch and YouTube begin at exactly the same time?
The HoYoLAB announcement said the YouTube post would follow Twitch by one hour. That is the schedule information supplied by the announcement; the YouTube video’s description confirms its September 27 publication but does not separately verify the one-hour platform gap.
What should a countdown page display for this event today?
It should identify the event as completed or expired and show the September 27, 2024 target time. A link to the official replay is more useful than a negative countdown or a new target date that was never announced.
Where can I verify the Version 5.1 maintenance start?
Check HoYoverse’s “The Rainbow Destined to Burn” Version 5.1 Update Details. It lists a 6:00 a.m. UTC+8 maintenance start on October 9, 2024 and an estimated five-hour duration.
Does the schedule page list the characters or rewards revealed during the program?
The cited schedule material does not establish a complete character, reward, or banner list. The official description only says that the program would feature details about new content and Version 5.1 developments, so specific reveal claims should be checked against the archived video or a separate official announcement.
