A Lot of Threes In the Same Day

The number 3 is found in several places in your numerology chart. It doesn't necessarily explain why the instances of the number 3 happened or why you keep remembering it. But it's a tool available for practicing numerology.

Your day of birth is a 3. That's likely to make you more sensitive to noticing the number when it's in your environment.

Your second life period cycle is the number 3. The cycle starts at the beginning of next year.

Two of your four challenge numbers are the number 3.

Your fourth pinnacle cycle is the number 3. The cycle starts in nineteen years.

Because your birth day is the number 3, you're likely to be more sensitive to that number than numbers with no significance for you. Sensitivity, in this case, meaning numbers you're familiar with and, thus, more likely to spot them when they're present in your environment.

That's all I'm seeing in your chart that might have a bearing on why you spotted 3 in so many ways and continue to remember it.

Although this isn't strictly numerology, I'll mention it anyway. Continuing to remember the number in the incident or circumstances may also have to do with wondering if it contains a special meaning. Wondering would set up a mystery. The mind is compelled to solve mysteries, which would be likely to keep the incident in front of mind.
