Dates in English and Spanish

In English we use ordinal numbers to express the date (first, second, third, etc.) while in Spanish we use cardinal numbers (uno, dos, tres, etc.).
For example,
Today is the 2nd of June / Hoy es el 2 de junio

To talk about the date we use the preposition 'on'. However, for months and years we use 'in'.

You came on the 12th of May / Viniste el 12 de mayo
You came in May / Viniste en mayo
You came in 1995 / Viniste en 1995

In English, months and days of the week are written with upper case while they are written with lower case in Spanish.

March / marzo Monday / lunes

In English, dates are written in the following order: month / day / year

June, 20th 1997 / 20 de junio de 1997 March, 3rd 2001 / 3 de marzo de 2001

In both English and Spanish, dates can be written with numbers and not letter. It is important to note that that the date format in the US is month/day/year whereas in UK (and Spanish) is day/month/year.

20 de junio de 1999: US= 6/20/2009 UK= 20/6/2009
