Dear @زينب سلمان الأمين,
Thank you for reaching out to the Microsoft 365 Q&A forum.
I completely understand how frustrating it is when you can't see your entire project timeline in your Gantt chart at once. It sounds like you're using a template that's pre-set to display a limited number of weeks, which is a common limitation with pre-built Gantt chart templates.
The core issue is that these templates typically have a fixed number of week columns, so when your project spans more weeks, the extra weeks simply don't appear.
To protect your workflow details and ensure you get the most accurate guidance for your specific setup, I've sent you a private message with tailored step-by-step instructions and some specific formula suggestions.
Please take a look at your private message inbox at your convenience. I've included some details there that should help you display all your weeks without having to rebuild your chart from scratch.
Thank you for your patience while we work through this together. I'm looking forward to hearing your results!
