Ever Wondered Exactly How Long That 200-Video YouTube Playlist Is? I Built a Solution

        We’ve all been there. You find an incredible educational series, a coding bootcamp, or a massive music collection on YouTube. You see it has 87 videos and you think, "Can I finish this over the weekend?" YouTube tells you the number of videos, but it stubbornly refuses to give you the total duration.

        As a developer (and someone who gets obsessed with productivity), this missing feature drove me crazy. So, I decided to stop complaining and start building. That’s how the YouTube Playlist Length Calculator was born.


Why I Created It

        I’m a big fan of "learning in public" and managing my time effectively. When I’m planning my week, I need to know if a tutorial series is a 5-hour commitment or a 20-hour marathon. I wanted a tool that was fast, clean, and didn't require me to log in or deal with intrusive ads. Honestly, I just needed something that works as hard as I do.

What It Does (And Why You’ll Like It)

        The tool is designed to be dead simple. You paste the link into https://www.playlistlengthcalc.com, and it gives you the breakdown:

  • Total Duration: Exactly how many hours, minutes, and seconds are in the playlist.

  • Playback Speed Adjustment: This is my favorite part. If you’re a 1.5x or 2.0x speed watcher like me, the calculator tells you exactly how much time you’ll save.

  • Average Video Length: Great for gauging if these are "bite-sized" clips or deep dives.

Behind the Scenes

        Building this was a fun challenge in working with the YouTube Data API and ensuring the UI felt snappy. I wanted something that stayed out of your way and just gave you the data you needed. It’s been a passion project of mine, and seeing people actually use it to plan their study sessions or workout playlists has been incredibly rewarding.

If you’re a chronic playlist hoarder like I am, give it a spin at playlistlengthcalc.com and let me know what you think! It's completely free and built for the community.

Why Hangzhou is the City I Can’t Stop Falling in Love With

Living in Hangzhou isn't just about being in a "tech hub"; it’s about finding a rhythm that balances the future with a very deep, poetic past. If you’ve never been to this corner of Zhejiang, let me walk you through the three "M’s" that make this place home for me: Mouthwatering Food, Majestic Views, and the Magnetic People. The Flavors (Meishi) Forget the heavy oils of some other regions. Hangzhou’s cuisine is all about "freshness." My absolute favorite is Longjing Shrimp . It uses the famous local tea leaves to give the shrimp a subtle, grassy aroma that just screams "springtime." Then there’s the legendary Dongpo Pork —braised until it literally melts the moment it hits your tongue. It’s the kind of comfort food that makes a long day of coding feel totally worth it. The Scenery (Meijing) You can’t talk about Hangzhou without mentioning West Lake . But here’s a local tip: don’t just go to the main tourist spots. My favorite time is early mo...
