Spanish speakers and English speakers think of their been tenses in much the same way: the present tense of English functions much like the present tense of Spanish and the same can be said of other tenses.
it is possible in both languages to discuss the future while using a present tense but you can do so more flexibly in English
in English you can use either the simple present or the present progressive to refer to the Future for example you could say either the bus arrives at 2 or the bus is arriving at 2 in Spanish however you must use a simple present
