Chronological Logic and Date Arithmetic
Calculating dates involves advanced Gregorian calendar algorithms:
- Leap Year Compensation: The system automatically detects whether a year has 365 or 366 days when calculating intervals crossing February 29th.
- Month Length Normalization: Adding '1 Month' adds a period corresponding to the specific month in sequence (e.g., adding 1 month to Jan 31st results in Feb 28th/29th).
- System Time Sync: All 'Today' calculations are synced with real-time system clocks to ensure your starting point is always current.
- Metadata Extraction: The tool doesn't just provide a date; it identifies the weekday, month number, and year for complete context.
Example Logic Check:
"What is 100 business days from Feb 25, 2026?"
The system skips 40 weekends to land on Wednesday, July 15, 2026.

Calendar Days
Every single day on the Gregorian calendar, including weekends and holidays. Used for legal statutes, warranties, and scientific tracking.
Business (Working) Days
