Tình huống sử dụng phổ biến

Deadlines

add 14 days, 6 weeks, or 3 months to find a target date.

Trip planning

count how many calendar days sit between two dates.

Backtracking

subtract a preparation window from a target date.

Gợi ý sử dụng

When a target month has no matching day, the result is clamped to the last day of that month.
Inclusive mode is for workflows that count the ending day as a full day.
Dates are handled as YYYY-MM-DD calendar dates to avoid timezone shifts.

Giới hạn & khả năng tương thích

This version does not exclude weekends or holidays, so it is not a business-day calculator.
It does not handle time-of-day or timezone conversion; use the timestamp converter for exact instants.
Contracts, payments, and legal deadlines can define their own counting rules.

Quyền riêng tư & bảo mật

Dates are calculated locally in your browser and are not uploaded.
