This also means that Yehovah in Heaven goes by the Hebrew calendar, which He established, and runs the universe and enacts His promises on His time clock. The new year recognized by Yehovah is the month of Aviv (Nissan), either in March or April, depending on the ripeness of the barley crop. Each month is 29.53+ days (the Moon phases) long. If there is cloud cover on what would be the 29th day, such that the renewed Moon (lower crescent) cannot be seen, a 30th day is observed by default.
