Question: How does one determine when the month / lunation will be 29 or 30 days?
Answer: Through measurement and calculation in the days leading up to the 29th, the time of conjunction is revealed so one can determine if the month has 29 or 30 days. No month ever has more than 30 days.

Example: Conjunction occurs on January 11, 2013 at 19:44 UTC. For Cairo, Egypt (UTC +2), Conjunction occurred on January 11 at 21:44 (9:44 PM) local time. This would mean that New Moon Day began on January 12 at 5:27 AM (Astronomical Dawn).
For your convenience, WLC has published all future Conjunction times through 2023 in the article, “Future Lunar-Solar Conjunction Dates (2013-2023).”
Now you know the time of Conjunction for your location, but when is the cut-off point? Scripture is clear that a day begins at Dawn, and in keeping with this Biblical premise, WLC employs Astronomical Dawn (hereafter referred to as "Dawn") for the end of one date and beginning of the next day. With that being said, this point in time also serves as the fulcrum for when New Moon Day begins. If Conjunction happens before Dawn, then New Moon Day begins at Dawn. If Conjunction happens after Dawn, then New Moon Day begins at the following Dawn. This methodology truly allows Yahuwah and the celestial system that He set in place to be the arbiters of time and it allows Him to create the date line.
Note: Based on the number of days already passed in the month, you can know if it will be a 29 or 30 day month.

At the heart of WLC is the true God and his Son, the true Christ — for we believe eternal life is not just our goal, but our everything.
While WLC continues to uphold the observance of the Seventh-Day Sabbath, which is at the heart of Yahuwah's moral
law, the 10 Commandments, we no longer believe that the annual feast days are binding upon believers today.
Still, though, we humbly encourage all to set time aside to commemorate the yearly feasts with solemnity and
joy, and to learn from Yahuwah's instructions concerning their observance under the Old Covenant. Doing so will
surely be a blessing to you and your home, as you study the wonderful types and shadows that point to the
exaltation of Messiah Yahushua as the King of Kings, the Lord of Lords, the conquering lion of the tribe of
Judah, and the Lamb of Yahuwah that takes away the sins of the world.
