Dear Isai,
The English language's tenses are 17. Down below I'll be showing you the tenses and their usage.
Simple Present / Present Progressive (or Continuous) / Simple Past / Past Progressive / Present Perfect / Present Perfect Progressive / Past Perfect / Past Perfect Progressive / Simple Future I (Will) / Simple Future I (Going to) / Future I Progressive / Simple Future II / Future II Progressive / Conditional I Simple / Conditional I Progressive / Conditional II Simple / Conditional II Progressive.
Basically, to figure out in what tense you should conjugate the verb, you need to look for any time indications (e.g. today, tomorrow)
