getTimes now constructs civDate = DateTime.utc(date.year, date.month, date.day, 12, 0, 0) at entry and passes it to both getSpa and getAngles. Previously a local DateTime in a positive-UTC-offset zone (e.g. UTC+12) would reach getSpa.toUtc() as the previous UTC calendar day, shifting all prayer times by ~24 h. Regression tests added for UTC/local DateTime consistency across UTC, EDT, and Auckland host timezones (27 tests, all pass).

## [Unreleased]
|
|
|
|
### Fixed
|
|
|
|
- Prayer times are now host-timezone-independent. `getTimes` normalizes the
|
|
caller's `date` to a stable UTC-noon reference (`DateTime.utc(y, m, d, 12)`)
|
|
before passing it to `getSpa` and all astronomical calculations. Previously,
|
|
a local `DateTime(2024, 3, 15)` in a UTC+12 zone would reach `getSpa` as
|
|
UTC March 14, shifting all times by one civil day.

## [1.0.0] - 2026-05-25
|
|
|
|
### Added
|
|
|
|
- Initial public release.
|
|
- `getTimes` — calculates Fajr, Dhuhr, Asr, Maghrib, Isha, midnight, and Qiyam times for any date and location.
|
|
- MCW seasonal model for Fajr and Isha twilight angles.
|
|
- Dynamic Prayer Calculation (DPC) algorithm with ML-calibrated depression angles.
|
|
- `PrayerConfig` — configurable madhab (Hanafi/standard Asr), calculation method, and UTC offset.
|
|
- Pure Dart implementation. Zero runtime dependencies beyond `nrel_spa`.
|
|
- Depends on `nrel_spa ^1.0.0` for NREL Solar Position Algorithm.
|
|
- Dart SDK `^3.7.0` compatibility.
|
|
- 24 unit tests covering all 7 prayer outputs across known locations and dates.
