Would you like to sleep until late on the holiday?
Why is there no alarm app that can handle holiday in Windows Store?
So, I made it!

This app is similar to alarm part of standard Windows Alarm & Clock except that:
(Feature)

• You can change the alarm on / off according to holiday.
• You can use holidays not only in Japan but around the world because holidays data is imported in a standard format (iCalendar: *. Ics) such as Google Calendar.
• Holidays data can be imported from the cloud but also manually define your own holidays.
• You can set not only holidays, but also forced weekdays (Sundays treated as weekdays).
• You can specify not only the day of the week but also the number of weeks in the month.
• You can specify not only day / week number but also month / day.
• You can import and export settings.
  (Limitation)
• You can only specify the default sound for the alarm in the desktop version.
• You can only specify ringtone for the alarm in the mobile version. If you want to play your own sound, please set it as ringtone beforehand.
• Vibration is not supported.
• You cannot specify snooze interval. Please choose from predefined interval when alarming. The default is 9 minutes.
