[Date Calculator] How many days left until ○○ ? / Free travel tools

Date Calucrator Web API

How many days until 〇〇? This is a free day calculation web app that allows you to calculate the number of days.

"When will the tickets go on sale for the plane I want to take?"

“What is the start date for booking mileage award tickets?”

"How many days until the big day?"

..and so on.

There are surprisingly many situations where you want to know the number of days until an important day. For example, in the case of travel, the reservation start date for airline tickets and mileage award travel is determined to be how many days before the departure date, etc., but you end up wondering, "When exactly is XX days ago?" and when the sales and reservations start. There are times when you miss out on a flight ticket and can't get a great deal.

We have created a "day calculation" web app that allows you to easily calculate the number of days until such an important day. There are four methods for calculating the number of days: "Number of days remaining until the specified date", "How many days before the specified date", "How many days after the specified date", and "How many days from the specified date to the specified date?". The number of days that can be calculated is 20 years before and after today, for a total of 40 years.

For your reference, we have also provided the flight ticket release dates and mileage award travel reservation dates for airlines such as ANA and JAL below, so be sure to use them when planning your next trip!
