Date Arithmetic & Calendar Calculations
Working Days vs. Calendar Days
Business deadlines, project sprints, and payroll periods typically rely on business days, which exclude non-working weekends (Saturdays and Sundays).
Leap Years & Gregorian Calendar
Our algorithm accounts for 365/366-day leap years (e.g. 2024, 2028) and variable month lengths (28, 29, 30, or 31 days) for accurate day counts.
Timezone Independence
Calculations run natively on your device in pure calendar day integers to avoid daylight saving and timezone drift anomalies.
