Molad Times - For the Jewish Years 5780 & 5781 (2020-2021)

When blessing the new month in the synagogue on the Shabbat before Rosh Chodesh, it is customary to announce the time that the molad (birth of the new moon) occurs in Jerusalem, so that it can be kept in mind while saying the blessing.

Traditionally, the time is announced in hours, minutes and chalakim — e.g., "The molad will occur Sunday evening, eight minutes and seven chalakim after seven o'clock." A chelek is one 1080th part of an hour, or 3.33 seconds. In this table, we have noted the time of the molad in hours and minutes (e.g., 7:08 PM), and we've also noted the number of chalakim, for use in the traditional announcement.

All times listed here are Jerusalem times, and are so announced in the synagogue regardless of location.

For more about the molad, see What is the molad? at the bottom of this page.

What Is the Molad?

The Jewish calendar is lunar-based, with each month representing one lunar cycle — the time it takes for the moon to complete one orbit around the earth.

The molad is the time of the moon's "birth." There is a point in the moon's orbit in which it is positioned directly between the earth and the sun, making it invisible to anyone standing on earth's surface. The molad occurs when the moon has moved far enough from this position that a thin crescent of its illuminated surface becomes visible, marking the start of a new Jewish month.

The time it takes for the moon to complete one orbit around the earth — as calculated by sages and confirmed by astronomical observation — is 29 days, 12 hours and 793 chalakim (there are 1,080 chalakim or "parts" in an hour, hence a chelek is 3.33... seconds). This represents the average time from molad to molad. The actual moment at which the moon becomes visible will vary slightly from the average molad, depending on the relative positions of the earth, moon and sun to each other at any given month, where on earth the observer is standing, the length of twilight at given seasons of the year, and other astronomical variables.

For this reason the Jewish calendar is “tweaked” so that Rosh Chodesh — the first of the month — is as close as possible to the time in which the moon would actually be seen in Jerusalem if we were still relying on actual observation of the moon to establish the start of a new month (as was done until the 5th century C.E.). Also, because a month has to be made up of whole days, the Jewish month alternates between 29 and 30 days. This is why Rosh Chodesh will often occur a day or more after the average molad.

How about a chart that shows not the Civil year calculations of Molad count of Helek but one of the full moon at twilight Passover when both the sun in the west and the full moon in the east being on opposite horizons .
How about a Chalakim count chart depicting that count of 1-18 just as you did the Molads of the New Moon. Reply

The map of Jordan looks like The Angel of the Lord's body. The map of Westbank looks like Hashem's Head extended out with another Head behind the Head sorta like a time lapse sequence of One moving forward in motion, and His Facial Features being the settlements of Judea in the Westbank. Even the city names corresponds to physical features even in Jordan. For instance both heads look the same having a similar outline landmark boundary lines and have meaning from the names of places to body parts. Like the Dead Sea looks like He is spewing water out of His mouth in that Head, but the Mouth of the other Head looks like His tongue is Jerusalem and the Dead Sea the spinal cord in the neck. The mouth in Jordan has a Blue Market and a school. You should check it out. Below is a link as follows:

It's neat and interesting how the molad on 10/17/20 happens at 3:23a.m and a chelek is 3.33 seconds. Reply

David Neil Blanchard Greenville July 7, 2020

So what is with the (Chelek) Chalakim only counting up to 17 and then no count the next month, then the count starts over on October 17th 2020? Reply

Bumy Goldson Beitar Illit July 7, 2020

in response to David Neil Blanchard:

There's 18 chalakim in a minute, so after 17 comes 0, and one more minute is added to the minutes.

It's similar to our clocks. Our clocks have 60 seconds in a minute but the clock will never say "60". 59 is the last displayed second, and after that it goes to "0", and another minute gets added to the minutes.

There's an interesting way to notice how the chalakim add up to a minute. Before October 17, 2020, all the minutes are even (since an even number of minutes (44) are being added each month to an even number) but starting from October 17th, all the minutes are odd. That's because the chalakim added up to 18 and equaled a whole minute, so that offsets all the even numbers into odd numbers. And now every month an even number of minutes (44) are added to the odd numbers, so they stay odd. Do you know what I mean? Reply

A chelek is 3 and one third seconds so there are 18 chalakim in a minute. It increases in the chelek column by one chelek every month. Every 18 months it comes to an even minute, no chalakim Reply

There is something huge about this but I can't quite figure it out yet. I wonder how many Molad minutes all these Chalakim's add up to and did it start when Israel bannered the Star Of David (26) 70ish years ago?

I just looked up where you're from and strangely enough the city you live in looks like the mouth of His face(Settlements of Judea as facial features, the head being outlined by the landmark boundary lines of the Westbank) That face, looking aerial view on a map, seems like it is set against itself toward the land of Israel , the Holy Royal Kingdom of Hashem.

Oh wait counting the first chelek at the start of this chart will get you to 14 when the even time passes over to odd times adding 44 mintues to each chalakim. That day is October 17th 2020! Reply

David NYC June 16, 2020

There is a free app called Kalendis. Not that easy to use but has the molad. But you have to know the day of the molad for it to show up. ( Sunday at 1 am counts as Saturday) You can also get moon phases for any day in history. i.e. when was the full moon at the time of the Exodus from Egypt Reply

A helek is 3.33 seconds or 1/18 minute. So that's why the Chelek counts to 17 then the next new moon the chelek is zero, then the following Molad (10/17/20) the Chelek count restarts. Intriguingly fascinating!!! Reply

OK, here's a more spelled out code (and no bugs I hope!)

This is in Python. You can easily adapt this to any other language. (In python, the "%" sign means modulate, like 17 % 4. In Excel or Visual Basic, it would be MOD(17, 4).)

To make sure it comes out right in the comment field, I'm going to separate each line with an empty line so if you see two lines one right after another then they're supposed to be on the same line.

I'm going to write out the code first and then I'll explain it.

#START CODE:

Year = 5780

Month = 1

Total_Months = int((Year + 10) * (12+7.0/19) - 136) + Month - 1

Day = int(1 + (23 + (11 + 6.0/18)/60)/24 + Total_Months * (1+((12+(44 + 1.0/18)/60)/24))) % 7

Hour = int(23 + (11+6.0/18)/60 + Total_Months *(12+(44+1.0/18)/60)) % 24

Minute = int(11 + 6.0/18 + Total_Months * (44 + 1.0/18)) % 60

Chelek = int(6 + Total_Months) % 18

print(Day, Hour, Minute, Chelek)

I am giving a talk on calculating the Hebrew calendar and using the Molads from this Chabad site. I am calculating for 5780 and after all calculations I completely agree with the Molad for Tishri shown here for 5781 That is on Thursday September 17, 2020. I don't detect any reason for postponement so Rosh Hashanah would be on Friday September 18, 2020 but I just received the 2020 calendar showing Rosh Hashana on Saturday September 19, 2020. Why? The postponement rule states that if Molad is on Friday, postpone but Molad is Thursday? I am very curious as to why? I notice the comment below by H.Lethbridge below and he is right, you should also show dates for Rosh Hashanah and why any postponement. Reply

Yehuda Shurpin for Chabad.org August 4, 2019

in response to Albert Jacobs:

While you are correct about the Molad and its implications for an ordinary month, there is an additional rule being overlooked. which is that the first day of Rosh Hashanah cannot be on Sunday, Wednesday or Friday. in the words of Maimonidies (Laws of sanctification of the moon 7:3):When the conjunction takes place at noon or after noon, and [Rosh Chodesh Tishrei would be] postponed to the following day - if that following day is either Sunday, Wednesday, or Friday, Rosh Chodesh is postponed again, and is established on the third day after the conjunction.

What is implied? If the conjunction takes place on the Sabbath after noon (in numbers, 7 - 186), in such a year Rosh Chodesh should be established on Monday. Similarly, if the conjunction takes place on Tuesday at noon or after noon, Rosh Chodesh should be established on Thursday.

For more on this rule see Kiddush HaChodesh - Chapter Seven Reply

I think it would be helpful to add the date(s) of Rosh Hodesh. Someone may not be familiar with the distinction between Rosh Hodesh and the molad and may use the molad date as Rosh Hodesh. And in any case it would be useful to include it. Reply

I want to thank you again for this chart. I print it out every four years or so and keep it in my Gabbai box. I would have to scramble for the molad each month without this. Just to let you know that you are appreciated. I think of you and bless you each month. Thank you and may Gd bless you to keep up your good work in the future. Reply

It's very good to be able to find this information, but something is missing.
It's all very well knowing the molad, but the chart doesn't tell you if there are one or two days of Rosh Chodesh, so how can you know which day(s) to say in the following prayer. Reply

Anonymous August 6, 2017

Actually, from what I picked up from another website, the molad & kiddish levana times aren't exactly Israel Standard Time either, but Jerusalem Local Mean Time, which is 20 minutes and 56.496 seconds later than IST, so subtract that value from the molad to get the IST equivalent. Reply

Michoel NJ July 25, 2017

Thanks for this. Now I understand 2 important points: The time announced is not local, nor affected by Daylight Savings; it's the moment of the molad, translated to IST (UTC+2). The other point was the molad is after the new moon, enough time to be seen. Reply

Do the Molads posted take into account Israel's Daylight Savings Time's or are all posted times always in Israel Standard Time (or whatever their term for it is) ? Reply

Giorgies E. Kepipesiom July 21, 2017

Not 29-1/2 The time it takes for the moon to orbit the earth is only 27-1/3 days, not 29-1/2. The reason the interval between one molad and the next is 29-1/2 days, is that while the moon has been moving, the suns position has also advanced, and so it takes a bit longer for the moon to catch up to the sun. The next molad will be when the moon catches up to the sun, not when the moon returns to where it was at the last molad. Reply

Re: M Friedman The above here is only intended as a brief overview on the Molad, the Jewish calendar in general is more complex (with entire works written about it). Here is another article on our site which gets into a bit more details. Reply

Emil M Friedman Hillside, NJ December 23, 2015

It has to be more complicated than described above. The molad is based on astronomy but we adjust the calendar to so that Yom Kippur can never fall on Friday or Sunday and so that Hoshanah Rabbah can never fall on Shabbat. Reply

There will be a partial solar eclipse on Friday, March 20, 2015. The eclipse times for Jerusalem are as follows:

Partial Eclipse begins Mar 20 at 11:17 AM
Maximum Eclipse Mar 20 at 11:58 AM
Partial Eclipse ends Mar 20 at 12:39 PM

The molad time published here for that date is 12:43 (3 chalakim) PM.

It's interesting that the molad time published here is only 4 minutes after the eclipse ends. I would think that the moon would still be way too close to the sun at that time to be seen. Is there no relation between the molad time published here and the actual time that the moon should first be visible? Reply
