Yes, today is the 1st day of Muharram.

Muharram is January in the Islamic calendar.

The number of months in the sight of Allah is twelve (in a year) – so ordained by Him the day He created the heavens and the earth; of them four are sacred; that is the straight usage. So wrong not yourselves therein and fight the pagans all together as they fight you all together. But know that Allah is with those who restrain themselves.” (Quran 9:36)

“The Prophet (PBUH) came to Madina and saw the Jews fasting on the day of Ashoora. He said, ‘What is this?’ They said, ‘This is a righteous day, it is the day when Allah saved the Children of Israel from their enemies, so Moosa fasted on this day.’ He said, ‘We have more right to Moosa than you,’ so He fasted ont hat day and commanded (the Muslims) to fast on that day.” (Bukhari)
