"Watch therefore, for you know neither the day nor the hour!"
The Biblical calendar is a lunar calendar adjusted with the sun and the seasons. Because of a Scripture in Colossians, some deduct that we are not to attach importance to certain calendar dates (Colossians 2:16), but we need to remember that the people that Paul chided for calendar observances where pagans. Paul himself observed Sabbaths, Passovers, Jewish festival, and the Yom Kippur fast which all were calendar base dates. God has asked that we ‘sanctify’ the New Moon (Exodus 12:2), meaning to set it apart. Setting apart the New Moon gets us all in sync celebrating festivals all at the same time. The Hebrew word used for Levitical Festival in Leviticus is ‘Mo’ed’: ‘appointed times’, appointment’. At these times we have a ‘date’ with the Creator; would we want to miss it?
Because of our undue independent nature, even something as simple as coordinating ourselves together with God has been a major issue over the centuries. A cloudy night could mess up the whole thing up. Also, with Jews living more and more outside of Israel, it became more and more difficult to synchronize everybody. To top it all, in the fourth century C.E., the Roman government desiring to stop the believers from observing Passover officially forbade the Sanhedrin in Jerusalem from convening and determining the New Moon. This had the desired effect of leaving everyone to their own devices creating division and chaos until today. As a result, the method of determining the moon by sighting fell in disuse and Jewish leadership started to do it through astronomical calculation. This is how the Hillel ll calendar was born. Until Yeshua returns and re-organizes the whole thing, it needs to suffice.
Days are important. There was a particular day when the door of the ark was shut, a determined day for the Children of Israel to put blood on their doorpost and for them to leave Egypt. In these cases, a calendar fluke would have had disastrous consequences. The Master followed the calendar dates of Passover scrupulously in His death and resurrection. The Sabbath also is a set day with particulars if not, how do intend to fulfill Yeshua’s injunction, “Pray that your flight may not be in winter or on a Sabbath” (Matthew 24:20)?
Even now a day is coming, a day which is the culmination of all of our calendar dates, a day which has been foreseen and predicted by all patriarchs and prophet. We are told that the only people who do not know that day are the ones living in the night of ignorance, but that those who live in the light of knowledge should know (1 Thessalonians 5:1-6). That day is a very special day. As the arrival of the day for the children of Israel to leave Egypt was punctuated by signs and plagues, so will the Day be of Yeshua’s return to avenge His people and judge the whole world. These signs will not be esoteric or mystical, they will be real and tangible, so that everyone will be able to recognize them. May we be ever faithful to study and obey the Word which gives us the light to know that Day!
