As a person
Born on the 23rd: athletic and strong, boosted by the 22nd next door.
A 23/5 life path is a 5: open, quick and always moving.
As a day
The 23rd, or a 23/5 day, is a 5 day: travel and change. The 22nd's build energy spills onto it.
As a year
A 23/5 year is a 5 year: change, travel and new routines.
Friends and enemies
As a 5. Friend: 3, the best. 9 is drawn to 5 and follows it. 7 works with space.
As a 5. Enemies: 4 and 6. With 11 the pair is volatile.
Friend numbers
Compounds
2+3 = 5, so 23 reads as a 5. Every 5 line applies to it.
The 22 next door adds build and strength to the 5.
