Linking to a specific start time in a video hosted on YouTube and embedding a YouTube video at a specific start time are simple techniques that have been around for awhile. Linking to a specific start time has been possible since at least March 2009, while embedding at a specific start time has been available since at least March 2010. Despite the age of these techniques, I’ve never had occasion to use them until this week(!), so I wasn’t familiar with them.
To link to a specific start time in a video hosted on YouTube, simply add a fragment identifier to the URL in the format
x is the integer minute to start at and
y is the integer seconds.
For example, to start at the 16th second of the video located at https://www.youtube.com/watch?v=eKbFb6TPVEA, add
#t=16s to the URL:
To embed a YouTube video at a specific start time, add a
start query string parameter to the URL of the embedded video. The value of the
start parameter should be the start time in seconds.
For example, to embed the following video with a start time 10 minutes and 37 seconds in, add
&start=637 (10 * 60 + 37) to the
