[**pray-calc v2.1.1**](../README.md) *** [pray-calc](../README.md) / MethodDefinition # Interface: MethodDefinition Defined in: [types.ts:104](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L104) Internal record for a single traditional method definition. ## Properties ### fajrAngle > **fajrAngle**: `number` \| `null` Defined in: [types.ts:115](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L115) Fajr depression angle in degrees. Null means the method uses a seasonal calculation (MSC) rather than a fixed angle. *** ### id > **id**: `string` Defined in: [types.ts:106](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L106) Short identifier used as the Methods map key. *** ### ishaAngle > **ishaAngle**: `number` \| `null` Defined in: [types.ts:120](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L120) Isha depression angle in degrees. Null means the method uses a fixed-minute offset or seasonal calculation instead. *** ### ishaMinutes? > `optional` **ishaMinutes?**: `number` Defined in: [types.ts:125](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L125) Fixed minutes after sunset for Isha. Overrides ishaAngle when set. UAQ uses 90 year-round; Qatar uses 90 as well. *** ### name > **name**: `string` Defined in: [types.ts:108](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L108) Human-readable name. *** ### region > **region**: `string` Defined in: [types.ts:110](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L110) Geographic region of primary use. *** ### useMSC? > `optional` **useMSC?**: `boolean` Defined in: [types.ts:130](https://github.com/acamarata/pray-calc/blob/af34aef986c37d8de9cf8db0744a41e3b0c99c40/src/types.ts#L130) When true, the method uses the MSC seasonal algorithm for both Fajr and Isha.
