No. There is the Gregorian calendar (used by Americans, Europeans, and Japanese), a Hebrew calendar, and a Muslim calendar at least. Here's a link to a Chinese calendar and an Indian calendar.

Unless you are willing to pay what a calendar collector would charge, I would make it myself or use a calendar from a year that has the same date to day of the week relationship, like 2009 or 2015 (it was a non-leap year that started on a Thursday).
It's hard to beleive, but exactly the same water as now.
During the year, due to the earth's orbit, different constellations appear during different seasons. You can use the constellations to determine the time of year.
At the same moment as what, and where on the earth? If you're asking if it can be 6 o'clock everywhere on the Earth at the same time... it could, if we all decided to use, say, Coordinated Universal Time (aka GMT). But currently, the existence of time zones mean that different locations always have different times.

Judaism uses lunar and solar together. They add an occasional leap-month to reconcile it to the solar calendar. Islam uses the lunar calendar exclusively. Druids use the Lunar calendar; and Christians use the Lunar calendar to calculate Easter every year. Some Satanists and Pagans use the Lunar Calendar. In fact the Lunar calendar is used by everyone to some degree.
No, calendar months are not the same across the world. While the Gregorian calendar is widely used, some regions may follow different calendar systems or have variations in how months are named or days are numbered. For example, some cultures have lunar calendars where months are based on the cycles of the moon.
Members of the Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" Church) use the year or calendar that is common in their culture. This means that the vast majority (those in 'Western' countries and highly developed nations) use the Gregorian Calendar. Those in countries using a Lunar calander (some Asian and Middle-Eastern countries) use the calendar their nation or culture uses, but are familiar with the Gregorian calendar. So, for the Mormons, it's the same year as it is for everyone else, 2010.
The alignment of the sunrise with a specific point at the same time each year is due to the Earth's axial tilt and its elliptical orbit around the sun. These factors create consistent patterns in the position of the sun relative to Earth, leading to annual events such as equinoxes and solstices, which determine the position of the sunrise.
You can find a reliable calendar on the google website. It has an app you can use for your phone. You can also go to the same page website and download a calendar for your computer.
The Philippines uses the Gregorian calendar, which is the most widely used calendar system in the world. This calendar was introduced in the Philippines during the Spanish colonial period and has been in use ever since.

The ISO calendar is primarily a fiscal calendar and does not change the names of the days of the week, although it does number them differently, starting with 1 on Monday and ending with 7 on Sunday, however Monday on the ISO calendar is also the same Monday on the Gregorian calendar (day 2) and the same Monday that is on the Jewish calendar. Shabbot (or Saturday) does not change. It is still on the same day. But all that is really not relevant, as the keeping of Shabbot is based on the command in the Torah which is based on the Hebrew calendar. So it would not matter what calendar was in use by any country, even if it did mess with the definition of the week, the Hebrew calendar remains the same.
the amans use a christian calendar.
