Planning Made Easy: Duration, Deadlines, and Star Dates

Saturday, January 24, 2026 Kitly Team

"How many days until..."

Dates are complicated. Calculating them shouldn't be. The Date Calculator provides three essential modes for project managers and developers:

1. Duration

Find the exact number of days between two dates. Perfect for calculating age, subscription lengths, or how long it's been since a specific event.

2. Add/Subtract

Need to know the date exactly 90 days from today? Or what the date was 3 weeks ago? Simply enter a start date and an amount, and let Kitly do the math.

3. Working Days (Business Mode)

This is our most popular feature for professionals. It calculates the duration between dates while automatically excluding Saturdays and Sundays. It's essential for accurate sprint planning and deadline estimation.

Bonus: The Temporal Scanner

Scroll to the bottom for a surprise! We've included a high-precision Star Trek Stardate converter (LCARS style) that calculates the current Stardate based on TNG and Kelvin timelines.
