⚠ WARNING! Daylight saving time (DST) applies to some regions of the world. Because of that, in the case of longer time ranges, the result obtained with this calculator may slightly differ from the actual one, as this calculator does not support Daylight saving time computations. Usually the difference between summer (DST) and winter time is no more than one hour (this is the case, for example, in the European Union). We will add the support for DTS to this calculator, if users ask for it - so let us know if you need it please.
Computing number of days between two dates is not a piece of cake. The main difficulty arises from the fact that different months have different numbers of days. In the Gregorian calendar (i.e. calendar used nowadays), months have 30 or 31 days. The exception is the February, which has 28 or 29 days every 4 years (leap year). Phew... it's not hard to get lost in this mess.
In order to avoid the difficulties, sometimes people use some simlpifications. For example, in the world of finances, there is bank year, which has always 360 or 365 days (depending on definition). Also, some banks assume that 30 days is equivalent of full month.
