                ##### Hololive Production Livestream Activity Statistics

                *(better user experience in desktop)*

                Lifetime statistics of HoloPro talents' YouTube channels.

                Based on YouTube livestreams up to **January 12, 2025**, queried using [Holodex API](https://docs.holodex.net/). This doesn't update live; I update this manually twice a month, but I wait a few weeks longer for new generations to have streams in each day.

                Data only includes **videos where Holodex has a record of its duration**, since some unarchived streams have its durations unrecorded. This is apparent when looking at the Archive Health of non-JP members who often do unarchived streams (it shows less than actual).

                Data may also contain "noise" as neither Holodex nor YouTube's API has a way to distinguish between livestreams and premieres. I had to put some arbitrary condition to filter most non-livestreams, which is that the duration should be more than 360 seconds. This is why the main Hololive channel is updated separately.
