Personal calendar: calculate every month

One year, twelve months

The personal calendar begins with the Personal Year and adds the number of each calendar month. Numerus reduces every total to 1–9. The resulting sequence can be checked and compared; its values do not measure the quality of months or predict events.

Explore your year

Enter your birth day and month, then the year you want to explore. Select a month in the calendar to see its total and every reduction step. All months have the same size; the accent only marks your selection.

Try the example with July 16 and the year 2026, or enter your own birth day and month. Birth year is not used in this calculation.

Personal Month 7 is the result of the total above, reduced to 1–9. This calendar explains the calculation; it does not assign a theme or forecast to the month.

Understand the monthly formula and why some values repeat

How was the Personal Year calculated?

1. Month
   7 = 7
2. Day
   1 + 6 = 7
3. Year
   2 + 0 + 2 + 6 = 10
4. Year
   1 + 0 = 1
5. Component sum
   7 + 7 + 1 = 15
6. Personal year
   1 + 5 = 6

Why do some values repeat?

There are nine possible results and twelve months. Under this rule, months nine positions apart have the same result: January and October, February and November, March and December. The repetition comes from reducing a sum, rather than a promise that the same events will happen again.

What changes when you choose another year?

First, the Personal Year is recalculated from the birth day, birth month and selected year. Then all twelve totals are recalculated. Moving from December to January therefore begins with the new Personal Year value; the sequence does not automatically continue by one more step.

What can you check next?

Choose two months with the same value and compare their starting totals. Then change the year and see whether the matching pairs remain. The calendar helps you follow this rule; it does not attach interpretations to the nine monthly results.
