Useful advice
Do not use counterfeit mobile phones.
Time units used in modern world are very diverse. The matter is complicated by the fact that in some cases they come from different cultures, differing from each other in the number system.
The division of the year into 12 months is associated with the duodecimal system that existed in Ancient Mesopotamia, in the same place - based on the lunar cycle - the length of the months was established, which was later clarified in Ancient Rome. The timing of the seven-day week has not been established. All these units of time counting have to be correlated with each other: 65 or 365 days, 12 months. It is also affectionate to know the number of weeks. And it will be determined by what year it is about, because this question is not as simple as it seems. Indeed, even in the modern "globalized" world, not all peoples live according to the same calendar.
Gregorian calendar
The most common in the modern world is the Gregorian calendar, introduced in the Catholic world at the end of the 16th century and later adopted by other countries, including Russia, although relatively late.
According to the Gregorian calendar, the length of the year is 365 days. Every fourth year is one day longer, such years are called leap years.
To calculate the number of weeks in a year, you need to divide 365 or 366 by 7. Both numbers are not even divisible by 7. The result is the number 52 and the remainder of 1 or 2. Thus, there are 52 full weeks in a year and one more day, "captured" from an incomplete week, and in a leap year there will be 2 such days, but this specification does not affect the number of weeks.
However, this calculation is based on the "ideal" option, when the year starts on Monday, the beginning of the year coincides with the beginning of the week. If the year starts on any other day, there will be 51 full weeks and 2 incomplete weeks in the year.
The seven-day week is currently used in many countries, so it is advisable to consider other calendars.
Islamic calendar
In some Muslim countries, the Islamic lunar calendar is officially used, and Muslims living in other states use it to determine the dates of their religious holidays. The structure of this calendar differs from the Gregorian one.
The length of the year according to the Islamic calendar is somewhat shorter than according to the Gigorian - 354 days. If you divide this number by 7, you get 50 and 4 in the remainder. Thus, according to the Islamic calendar, there are 50 full weeks and one incomplete or 49 full and 2 incomplete weeks in a year.
Jewish calendar
The most difficult situation is with the Jewish lunisolar calendar, officially adopted in Israel along with the Gregorian one. According to this system, a 19-year cycle is distinguished, consisting of 12 simple years and 7 leap years, and the difference between them is not one day, but 30. Any year - both simple and leap years - can be "correct" (simple year - 354, leap - 384), "sufficient" (355 and 385) or "insufficient" (353 and 383).
Accordingly, in simple year according to the Hebrew calendar, there will be 50 full weeks and 1 incomplete, and in a leap year - 54 full weeks and 1 incomplete. The number of days remaining depends on the type of year.

This function, when enabled, in theory, should significantly improve the quality of the transmitted speech, but, unfortunately, it must be supported by the operator. cellular... During its operation, the phone's power consumption in the talk mode slightly increases (about 5%). As far as is known, none of the Russian cellular operators does not support this function. The principle is based on a different speech compression algorithm (ACELP) and occupies a wider bandwidth.

# 4720 # disable Half Rate Codec (HFR)
HR CODEC (Half Rate)
Significantly degrades the speech quality, but saves the battery by about 30%. Again, must be supported by the cellular operator.
