Reference 2024-03-01 → Target 2024-02-28
D+2The target was two calendar days before the reference date.
Questions & answers
Is the starting day included?
No. The reference day is day zero, so tomorrow is D-1. Some anniversary counters count the first day as day one; that convention differs from this countdown.
Does it count hours or working days?
No. It compares calendar dates only. Weekends and public holidays count as ordinary days, and the time of day does not affect the result.

Questions & answers
What happens if both dates are the same?
Elapsed counting returns zero days. Inclusive counting returns one day because the single calendar date is included.
Is this a business-day calculator?
No. Every calendar day counts, including weekends and public holidays. Weeks mean groups of seven days, not named calendar weeks.
