METHODS TIME METHODS

AddDate

Returns the time corresponding to adding the given number of years, months, and days to the given time.Time value.

Syntax

TIME.AddDate YEARS MONTHS DAYS

Returns

time.Time
{{ $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

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.

See this explanation from the Go team.

{{ $d := "2023-01-31" | time.AsTime }}
{{ $d.AddDate 0 1 0 | time.Format "2006-01-02" }} → 2023-03-03

{{ $d := "2024-01-31" | time.AsTime }}
{{ $d.AddDate 0 1 0 | time.Format "2006-01-02" }} → 2024-03-02

{{ $d := "2024-02-29" | time.AsTime }}
{{ $d.AddDate 1 0 0 | time.Format "2006-01-02" }} → 2025-03-01
