```go-html-template
{{ $d := "2022-01-01" | time.AsTime }}

{{ $d.AddDate 0 0 1 | time.Format "2006-01-02" }} → 2022-01-02
{{ $d.AddDate 0 1 1 | time.Format "2006-01-02" }} → 2022-02-02
{{ $d.AddDate 1 1 1 | time.Format "2006-01-02" }} → 2023-02-02

{{ $d.AddDate -1 -1 -1 | time.Format "2006-01-02" }} → 2020-11-30
```

> [!NOTE]
> When adding months or years, Hugo normalizes the final `time.Time` value if the resulting day does not exist. For example, adding one month to 31 January produces 2 March or 3 March, depending on the year.
