Olena vs Silje
Olena and Siljecompared on official birth-registration statistics and Namewise's recorded data. This page states what each name's record shows — it never picks a winner or scores one name against the other.
Head to head
Ranks are only compared within one published list and one year. Two ranks from different years, from a boys' and a girls' list, or from different registrars are not comparable, so they are not placed side by side.
Norway · Girls

Olena and Silje over time
Olena and Silje appear together in 1 published list, across 25 years of shared records. Silje held the stronger position in more years in 1 of them, Olena in 0.
The order between them changed and held in one of those lists — a change in that published list, never a claim that one name displaced the other.
Olena reached its own highest recorded position earlier in 1 of those lists, and Silje in none. Each position is a place inside its own list, so this compares when they peaked and never how high.
Counted list by list. Two names in the same published list are measured on the same scale in the same year, so those comparisons are real — but positions from different lists are not, so nothing here is combined into an overall standing.
