## Version history (last 5 releases)

### 2.1.1 — 2026-07-21

v2.1.1 — Bug fix

Fixed an issue with the Week Grid display.

### 2.1.0 — 2026-07-15

v2.1.0 — A more accurate measure of your remaining time.

Final day estimates are now based on the average remaining life expectancy for your current age (Japan's 2024 Abridged Life Tables, Ministry of Health, Labour and Welfare), rather than a fixed average lifespan at birth. Because it accounts for the years you have already lived, the estimate becomes more accurate — especially later in life.

· Male/female presets now use remaining life expectancy at your current age
· Editing your birth date now offers to recalculate your final day
· Your existing final day will never change on its own

A slightly truer number to sit with.
