Pobre "he" Someone has left you out.

Hola Gerald R

The sentence "Esta vez me he acordado de nuestro aniversario" is not translated as "This time I have remembered our anniversary" because of the differences in how Spanish and English handle the present perfect tense.

In Spanish, the present perfect (me he acordado) is often used in contexts where English would use the simple past tense (I remembered). This is especially true when talking about events in a completed time frame that still feels relevant to the speaker's current perspective.

The phrase "This time" provides a specific time frame (a completed action), so English prefers the simple past tense to match that context.
