Hebrew dates for a given Parasha over a period of 10 years
Is there a way I can find the Hebrew dates for, say, Parashat Yitro, for a period of about 10 years - 1918 thru 1928? I’m trying to deduce a Gregorian birthdate for a family member in order to search for archived birth records.
What we have is a partial date in Shvat, and positive knowledge that it was the week of Parashat Yitro.
It would also be convenient (but not essential) to have equivalent Gregorian dates.
Short of the hard way, Is there any way of doing this now?
TIA
Josh
Answer
I didn't realize you were looking for an API. If you've got some software engineering expertise, you can do this even more easily in JavaScript using the @hebcal/core package.
const {Sedra} = require('@hebcal/core');
for (let year = 5677; year <= 5689; year++) {
const sedra = new Sedra(year);
const hdate = sedra.find('Yitro');
console.log(hdate.toString() + ' - ' + hdate.greg().toLocaleDateString());
}18 Sh'vat 5677 - 2/10/1917
20 Sh'vat 5678 - 2/2/1918
24 Sh'vat 5679 - 1/25/1919
18 Sh'vat 5680 - 2/7/1920
20 Sh'vat 5681 - 1/29/1921
20 Sh'vat 5682 - 2/18/1922
24 Sh'vat 5683 - 2/10/1923
20 Sh'vat 5684 - 1/26/1924
20 Sh'vat 5685 - 2/14/1925
22 Sh'vat 5686 - 2/6/1926
19 Sh'vat 5687 - 1/22/1927
20 Sh'vat 5688 - 2/11/1928
22 Sh'vat 5689 - 2/2/1929
You could also do this with our REST APIs using one URLs per year like this:
https://www.hebcal.com/hebcal?cfg=json&v=1&maj=off&s=on&year=1918&leyning=off
Or a multi-year query like this:
https://www.hebcal.com/hebcal?cfg=json&v=1&maj=off&s=on&start=1918-01-01&end=1928-12-31&leyning=off
And then you'd have to filter for Parashat Yitro, then convert from Gregorian dates to Hebrew calendar dates.
Thanks, but I already know how to do that.
What I’m looking for is, say, a REST script that will let me explore a range of years for a single Parasha.
The work I have to do with the results from that script is check the entire range of dates for plausibility. IOW, plausibility means that one of the birthdate represented by the Parasha *and* the six days that follow it can be plausibly explained as the person’s birthdate, for example 5 Shvat might have been 3 Shvat, 13 Shvat, 15 Shvat or 25 Shvat if it was copied incorrectly.
Having to do all of that one by one is a bit laborious.
Hopefully, this makes sense.
Hi Josh, thanks for using Hebcal and thanks for your question.
You can visit the Parashat Yitro page on Hebcal and next to the recent dates you'll find a search box that says "Look up the date of Parashat Yitro in a past or future year"
If you enter those 10 years (1918 through 1928) you should be able to get the dates (both Gregorian and Hebrew) pretty quickly.
