21:12 Meaning: What the mirror hour means?

What does 21:12 really mean?

What is the mirror hour of 21:12?

If you are wondering what 21:12 means (maybe something happened at that time) I am excited that you are here. It is known as a mirror hour and that is because it is reversed. e.g. 21:12 is reversed and this is significant, which I will talk about below.

If you see 21:12 on social media, clock or you look at this time for some mad reason. It is saying you have decided to step in this timeline and noticed this probably on the clock.

The "Mirror Hour" reading is 21:12. If you don't know the traditional mirror hours include times with numbers in both the same positions but reversed (for instance, 21:21, or 12:21), as well as mirror numbers on the left and right sides of the clock without corresponding numbers on the other side. Let me explain a little more,  21:12 does not quite fit into the mirror hour definition. More aptly described would be a patterned time, or simply noticeable, but we would still want to be mindful of it.

  • What does 21:12 for love: If you're single, read 21:12 as love is coming, it is like a reunion (due to the 2 x2 in this mirror hour). If you are not single then focus on doing the work on yourself. If you're already with someone, my signs might point to an unworn relationship, one that needs patience as much as it might provoke doubt.
  • What does 21:12 signs for a twin flame: You're on a twin flame journey, and it's easy to see that when you're seeing 21:12 over and over again, separation isn't the final word. The reading says, "delay" a bit like the tarot hanged man in that things are in delay, In the twin flame context, this could really be that you will come back together because of the 22 meaning union.
  • What does 21:12 a.m: this can mean things are shifting over the next 48 hours and most people know that things will get better but seeing this in the morning is good omen. It means change.
  • What does 21:12 pm: Some people think that time (9:12pm on a 24-hour clock) but in my spiritual practice this can mean something unexpected (but good) will happen.
  • What does manifestation mean? In manifesting work, we often look for sudden wishes being granted, if you see 21:12 this to me, can indicates you must stay in your process. Remember, Daniel waited 21 days, knowing his 70 answered call was already on its way to him.
  • What does 21:So what does 12 mean as an angel number? Some spiritual people (me as one) believe angels use number sequences to help you learn from your life experiences, as opposed to telling you what the future holds. What the number 21:12 means is that your path of progress is well under way, but your journey is not complete, and more good things are comning. Also expect a phone call.

What is the biblical meaning of 21:12?

I spent years looking into the bible, especially the book of Encoch at numbers, specifically Biblical numerology is a long-standing angel number focus and I do think if you see 21:12 the veil is being pulled back.  What does 21 actually mean. We are now approaching the time where you are seeing a time that is significant.

Turning to the bible, the revelation 21:12 describes how the New Jerusalem has 12 gates and " the name of the twelve tribes of Israel and what was written on this." I find it significant that 12 is mentioned in context, but it doesn't prove numerology -- I believe 21:12 is worth looking up and reading anyway.

What does the number 21 really mean?

21 in scripture pops up allot. It is also associated with the promise of deliverance, or breakthrough, 21 is clearly associated with a long period of "waiting and watching." Daniel (in Daniel 10:12-13) spent 21 days of prayer after which an angel informed Daniel that his prayer was heard right away and that 21 days had passed because spiritual forces held up the answer until Michael "strong man" the Archangel Michael then got involved. This all connects to a delayed response, which indicates that, although the answer is on its way, there are obstacles that need to be bypassed or cleared away.

Mathematically, that's worth noting as well while I am on the subject that 21 is three times seven. Three in scripture is the number associated with divine completeness, multiplied by 7 this is, the most consistent symbol for rest and wholeness, implies this isn't by accident, that it means something deeper. To me this is real completion earned and attained through perseverance and steadfastness.

What does the '11' mean?

I am literally breaking this down for you, so the number 11 is another number that is frequently (and falsely) associated with positivity. It's a bit less well-known than 111, however, it is considered a symbol of chaos, since it is one less than the number 12, often described as representing harmony and total control (remember the 12 tribes, the 12 apostles, the 12 gates of the New Jerusalem, etc).

I find two especially clear examples. In the second most important story in the Bible, which is Genesis 32:22 -- Jacob's "family" only had 11 sons (still waiting for Benjamin to come). The story of the Tower of Babel in Genesis 11, for its part, is the classic example of an ambitious human effort going awry, not in a state of chaos but on the edge of this.

What does 22 Mean?

22 also for me is a bit more about making sure you complete stuff in life. The point which I want to make is that numerologically the 11 seems unfinished, and in the biblical sense the 22 is something that seems completed. The reason I mention this is that 21:12 is going to be both. Completion of something and something kind of left unfinished.

What does it mean that the digits of the hour 21 and minutes 12, add up to 6?

I think this is actually one of the more interesting of all the things I have said. So far I want to focus on the fact that one, two, two, two equals six. And six is a number that carries a very weight in the spirit world, just short of the seven, the number that is complete, the number of God when He creates, as he created for six days and resting on the seventh. So I will say, it is common to take a view of 6 as the work that was yet to be done, still a work in progress on the human side as compared to the completion on the divine side.

What's the real meaning of 21:12?

So if you keep seeing the number 6 as well as 21:12 on the clock, it means you're striving toward something. Expect delays, but also expect completion.
