Zemanim issue ?
Closed this issue · 1 comments
hi wrote the following code:
import {HebrewCalendar, months, HDate, Location, Event, ParshaEvent, Zmanim} from '@hebcal/core';
const loc = Location.lookup('Jerusalem');
const wed = new Date(2023,9,20);
const zeman = new Zmanim( wed, loc.getLatitude(), loc.getLongitude());
console.log("sunrise:" + zeman.sunrise())
console.log("sunset:" + zeman.sunset())
the output i'm getting is :
sunrise:Fri Oct 20 2023 06:45:38 GMT+0300 (Israel Daylight Time)
sunset:Fri Oct 20 2023 18:01:50 GMT+0300 (Israel Daylight Time)
it's writing "Fri" as for Friday instead of Wednesday
also, it's outputting GMT+0300 instead of +2
also it's outputting "Oct" instead of September
what am i doing wrong ?
if i send in the Date (2023 , 8 , 20) then it will get the right resualts (meaning you are still using based on 0-11 months
but still the GMT is wrong
As you noted, new Date(2023,9,20) indeed is Friday October 20. For Wednesday September 20, you will need to use new Date(2023,8,20). This is not related to the Hebcal library, but rather standard JavaScript Date object
year
Integer value representing the year. Values from 0 to 99 map to the years 1900 to 1999. All other values are the actual year. See the example.
monthIndex
Integer value representing the month, beginning with 0 for January to 11 for December.
day Optional
Integer value representing the day of the month. Defaults to 1.
Separately, GMT +3 is the correct offset for Israel between the dates Fri, Mar 24, 2023 – Sun, Oct 29, 2023
