Holidays

the The mMexican celebration of the independence is close, and . And we are going to supposed to scream, "viva Mexico!" I think it's like Long Live Mexico!, The celebration started  starts on sSeptember 15 at midnight, with the traditional scream of each local president in each city of Mexico, includes  including the president of all the republic, where he who screams, about "long live Miguel Hidalgo, Long Live Our Heroes," and also screams mostly the names of the people who participated in the movement of 1810. And the celebration finished finishes (or ends) on s September 16 with an army desfile parade, well I don't know but when all the army marches in each town, showing their uniforms.
I believe this year, the celebration will be long, with the beginning on sSeptember 13,14,15,16, (you should only list the beginning date), and in some states like cChiapas, they are going to celebrate the annexation of Chiapas to Mexico.
This state was part of the kingdom of Guatelama during the Spanish colony, but later it become a territory in dispute with the new nation of Mexico and Guatemala. , fFinally they decided to become part of Mexico.

A few general corrections:  places, proper names, months, and days of the week should always be capitalized in English, as should the first letter in a sentence.  You used some past tense where future tense is required.  The other thing I see here is that you have what we call run-on sentences.  These are sentences with too many subjects and objects in one sentence without enough punctuation.

Yo recomiendo que uses la palabra "shout" (tanto como verbo como sustantivo) y no "scream". Un "scream" es algo descontrolado, como cuando te enfrentas a algo escalofriante. Un "shout", en este contexto, es algo más controlado y digno, y la palabra "shout" traduce perfectamente el histórico "grito".

Debo añadir que a veces la frase completa "Grito de la Independencia" se traduce como "The Cry of Independence", lo cual suena muy bien en inglés. (En inglés "cry" no siempre significa "llorar"; también puede significar "grito/gritar") Pero en tu párrafo, como no intentas traducir la frase completa (El Grito de la Independencia), hay que utilizar la palabra "shout".
