What this calculator does
This calculator finds the exact midpoint date between two dates — useful for pregnancy milestones, long-distance countdowns, project timelines, or splitting a trip in half.
Worked example
Between January 1, 2026 and March 1, 2026, the halfway date isFriday, January 30, 2026.
Common mistakes
- Confusing the midpoint with the average calendar date. The halfway point is based on the number of elapsed days, not simply averaging month and day numbers.
- Forgetting leap years. A leap day within the range shifts the exact midpoint by a day compared to a naive month/day average.
