| 100 days | 100 days | A popular day-count milestone, especially online. |
| Six months | ~182 days | Half a year in — the relationship feels settled. |
| One year | 365 days | Your first full anniversary, the big early one. |
| 18 months | ~547 days | A quieter midpoint many couples still note. |
