30 Day Calculator

Calculate what date will be 30 days from any starting point. This calculator helps you plan projects, track deadlines, and manage time-sensitive tasks with ease.

How It Works

The calculator uses date arithmetic to compute future or past dates:

$\text{End Date} = \text{Start Date} + \text{Days}$

The calculation takes into account:

• Month transitions
• Year transitions
• Leap years
• Different month lengths

Date Calculations

Standard Month Transitions

• 30-day months: April, June, September, November
• 31-day months: January, March, May, July, August, October, December
• February: 28 days (29 in leap years)

Special Cases

• Year End: December 31 + 30 days = January 30
• Leap Year: February 29 exists in leap years
• Month End: Adjusts for varying month lengths
