Jews do not refer to God as Allah and so do not have a day to worship Allah. Allah is a Muslim term for God.
Although in modern times it is very ecumenical to say that the Jews and Muslims worship the same God, many orthodox Jews and Muslims would disagree and so it is not proper to confuse the two religions and their doctrines, revelations, or types of worship.
The main day of worship on the western Gregorian calendar for Jews is Saturday. For the Muslims it is Friday.
Answer
Many Jews from Arab countries do in fact use the name Allah when referring to God. Religious Jews pray 3 times a day, every day. Shabbat starts Friday at sundown and ends Saturday night. Prayers are done 4 times on Saturday.
Jews may engage in private prayer at any time or place.
For public prayer (meaning prayer services in groups of at least 10 people, often in a synagogue):
Virtually all self-identified Jews participate in some form of public worship on Yom Kippur and/or Rosh Hashana.
Somewhat fewer do so at the services on the other holidays, including Passover, Shavuot, and Sukkot.
Somewhat fewer than that do so at the services on the weekly Sabbath, and some only on Friday nights.
Somewhat fewer than that worship either in public services or in private for the daily evening, morning, and afternoon prayers.
Religious Jews pray 3 times a day, every day. Shabbat (the Jewish Sabbath) starts Friday at sundown and ends Saturday at sundown. Prayers are done 4 times on Saturday.
Synagogue services are held three times a day, every day of the year.Weekday morning prayer lasts about 45 to 60 minutes.
Afternoon services and the evening service are often consecutive, beginning around 15-30 minutes before sunset.
Sabbath (Saturday) morning service will commonly begin at 7:30 a.m. or later. This prayer is for about 2-3 hours.
