The callendar is irrelevant. The key is the year shown in the intro: 201X. It sets the beginning, while the seeds that sticked to Asriel in village and later turned into flowers are determining the duration and the end of discussed period of time with an accuracy of few months, maybe a couple. The exact year isn't that importantant as same as lenght of that period, but it can be estimated at less than one year. For more details, check my profile. Thing isn't perfect, but I think it might do the trick.
