How is year progress calculated?

Year progress measures the exact fraction of milliseconds that have elapsed since midnight on January 1st relative to the total number of milliseconds in the current calendar year (365 days in common years, 366 days in leap years). The percentage updates in real time down to four decimal places.

What is an ISO 8601 week number?

ISO 8601 defines a standard calendar week numbering system where Week 1 is the first week containing at least 4 days of the new year (or the week containing the first Thursday of January). Weeks always begin on Monday and end on Sunday.

What is the difference between calendar quarters and financial quarters?

Calendar quarters divide the year into four 3-month blocks: Q1 (Jan–Mar), Q2 (Apr–Jun), Q3 (Jul–Sep), and Q4 (Oct–Dec). Some organizations use fiscal or financial quarters with different start months, but standard ISO calendar quarters follow the standard Gregorian calendar.

Does the New Year countdown automatically adjust for my timezone?

Yes. The countdown timer calculates the exact remaining days, hours, minutes, and seconds until midnight on January 1st in your device's local timezone, so your countdown aligns perfectly with local midnight celebrations.

历法季度将一年划分为四个3个月区间：Q1（1-3月）、Q2（4-6月）、Q3（7-9月）和Q4（10-12月）。部分企业采用不同起始月份的财年季度，但标准季度严格遵循公历。
