Deadline Calculator

Stop staring at your calendar and manually counting days around weekends and holidays... The "finger-counting" era is over—this tool was born to automate the entire process. By simply entering your workload, it instantly calculates accurate "Start Dates" and "Due Dates" excluding non-working days. "If the final delivery is January 20th, when is the absolute latest we can start?" "If we start today and spend 10 workdays on design, when will it be published?" We turn these tedious scheduling headaches into a one-second process, right in your browser. The standout feature is its ultimate flexibility. In addition to calculating forward from a start date (Standard Mode), it features a "Reverse Mode" to find the necessary start date from your deadline. Plan your projects with the method that best fits your specific needs. An incredibly intuitive experience. Each step is as simple as inputting your man-hour days. Everything happens right in your browser—no complex math required. Weekends and public holidays are automatically excluded by default. Need to account for custom breaks like summer vacations or office holidays? You can easily add them in the settings. Switch layouts to match your workspace. Based on the comprehensive "Horizontal Layout," you can swap to the space-saving "Vertical Layout" with a single click. Whether you want to work side-by-side or focus on the full view, the choice is yours. Sharing your schedule is just a click away. Copy your calculated table and paste it directly into Excel or Google Sheets. The formatting remains intact, making it perfect for quick client proposals and drafting Gantt charts. Manage up to 8 custom phases, tailored to your specific workflow. "Strategy," "UI Design," "Frontend," "QA"... Your custom workflow, your own template. With an adaptive dark mode that automatically adjusts text contrast based on your current background. You get optimal visibility no matter where you work. To every Web Director, Designer, Engineer, and Project Manager: Leave the math to us and stay focused on your core creative work.
