What is the Due Date Calculator?
Managing project timelines, legal deadlines, or academic assignments often involves complex date math, especially when you need to exclude weekends or holidays. The Due Date Calculator automates this process. You can input a starting date, add a specific number of days, weeks, or months, and instantly find the exact future deadline. You can also toggle the 'Business Days Only' switch to automatically skip Saturdays and Sundays. Powered by local browser APIs, all calculations happen instantaneously without your proprietary schedules ever being uploaded.
